好书app中用到的常用第三方库的总结

在好书app中有很多常用的第三方库，自己总结一下在以后的项目中也可以应用

好书app中用到的常用第三方库的总结

shareSDK主要是一个分享功能，可以分享到微信,qq等，主要是要去看他的官网，注册app即可

HZPhotoBrower主要是图片放大的时候用到的在点击图片的时候可以放大图片，可以选择放大图片时只有一张，或者轮播，有好几张随后设置当前是在第几张

还要设置代理，和代理实现的方法

//实现图片点击时的放大
    func photoBrowser(sender:UITapGestureRecognizer){
        let photoBrowser = HZPhotoBrowser()
        //放大图片的个数
        photoBrowser.imageCount = 1
        //当前浏览的是第几张图
        photoBrowser.currentImageIndex = 0
        //代理
        photoBrowser.delegate = self
        photoBrowser.show()
    }
    //实现photoBroswer的回调
    func photoBrowser(browser: HZPhotoBrowser!, highQualityImageURLForIndex index: Int) -> NSURL! {
        //最终放大的图片
        let coverFile = self.bookObject!["cover"] as? AVFile
        return NSURL(string: coverFile!.url)
    }
    func photoBrowser(browser: HZPhotoBrowser!, placeholderImageForIndex index: Int) -> UIImage! {
        //缓冲图 在加载过程当中
        return self.bookTitleView?.cover?.image
    }

leftSwipeCell主要是在tableView中，当上一个左滑的时候，下一个就要把左滑的显示去掉将自定义的tableViewCel继承自SWTableViewCell

import UIKit

class pushBookTableViewCell:SWTableViewCell{
//自定义cell
    var BookName:UILabel?
    var Editor:UILabel?
    var more:UILabel?
    //当前展开的是哪一个cell
    var swipCellindexPath:NSIndexPath?
    //封面
    var cover:UIImageView?
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }
//初始化的方法
    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        //移除所有的cell
        for view in self.contentView.subviews{
            view.removeFromSuperview()
            self.BookName = UILabel(frame: CGRectMake(70,8,242,25))
            self.Editor = UILabel(frame: CGRectMake(78,33,242,25))
            self.more = UILabel(frame: CGRectMake(78,66,242,25))
            self.BookName?.font = UIFont(name: MY_FONT, size: 15)
            self.Editor?.font = UIFont(name: MY_FONT, size: 15)
            self.more?.font = UIFont(name: MY_FONT, size: 15)
            self.contentView.addSubview(BookName!)
            self.contentView.addSubview(Editor!)
            self.contentView.addSubview(more!)
            self.cover = UIImageView(frame: CGRectMake(8, 9, 56, 70))
            self.contentView.addSubview(cover!)
                   }
    }
  
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

}

//记录上次左滑的按钮 
    var swipeCellIndexPath:NSIndexPath?

继承他的协议

SWTableViewCellDelegate

//删除和编辑的按钮只能在一个cell钟出现
    func swipeableTableViewCell(cell: SWTableViewCell!, scrollingToState state: SWCellState) {
    let indexPath = self.tableView?.indexPathForCell(cell)
        //当前有展开的按钮
        if state == .CellStateRight{
            if self.swipeCellIndexPath != nil && self.swipeCellIndexPath?.row != indexPath?.row{
                //遮盖住
                let swipeCell = self.tableView?.cellForRowAtIndexPath(self.swipeCellIndexPath!) as! pushBookTableViewCell
                swipeCell.hideUtilityButtonsAnimated(true)
            }
                //将当前的左滑的cell记录下来
                self.swipeCellIndexPath = indexPath
            //没有左滑的cell
        }else if state == .CellStateCenter{
            self.swipeCellIndexPath = nil
        }
        }
    //当点击右滑的两个按钮的时候
    
    func swipeableTableViewCell(cell: SWTableViewCell!, didTriggerRightUtilityButtonWithIndex index: Int) {
        //将点击的cell隐藏起来
     cell.hideUtilityButtonsAnimated(true)
        let indexPath = self.tableView?.indexPathForCell(cell)
        
//是编辑的这个按钮
    let object = self.dataArray[(indexPath?.row)!] as? AVObject
        if index == 0{
            let vc = pushNewBookController()
            vc.fixType = "fix"
            GeneralFactory.addTitleWithTile(vc, title1: "关闭", title2: "发布")
            
            vc.bookObject = object
            self.presentViewController(vc, animated: true, completion: nil)
            
        }else {
            //删除的操作
            ProgressHUD.show("")
            //删除讨论区和点赞区的所有有关这本书的信息
            let discussQuery = AVQuery(className: "discuss")
            discussQuery.whereKey("BookObject", equalTo: object)
            discussQuery.findObjectsInBackgroundWithBlock({ (results, error) -> Void in
                    for Book in results {
                        let BookObject = Book as? AVObject
                        BookObject?.deleteInBackground()
                    }
                })
                
                let loveQuery = AVQuery(className: "Love")
                loveQuery.whereKey("BookObject", equalTo: object)
                loveQuery.findObjectsInBackgroundWithBlock({ (results, error) -> Void in
                    for Book in results {
                        let BookObject = Book as? AVObject
                        BookObject?.deleteInBackground()
                    }
                })
                
                object?.deleteInBackgroundWithBlock({ (success, error) -> Void in
                    if success {
                        ProgressHUD.showSuccess("删除成功")
                        self.dataArray.removeObjectAtIndex((indexPath?.row)!)
                        self.tableView?.reloadData()
                        
                        
                    }else{
                        
                    }
                })
                
                
            }
    }

inputView主要是在讨论区中，他可以自带的键盘和文本框，并且有评论这个按钮可以将文本加入到tableView中

继承他的协议InputViewDelegate 从xib进行加载在加入inputView的时候最好下面覆盖一层灰色的背景layView

self.input = NSBundle.mainBundle().loadNibNamed("InputView", owner: self, options: nil).last as? InputView

func connect(){
        //发表评论的时候 从xib加载发表评论的文件框，因此加载方法和纯代码创建的时候不同
        if self.input == nil{
            //从xib 加载的 只有一个对象
            self.input = NSBundle.mainBundle().loadNibNamed("InputView", owner: self, options: nil).last as? InputView
            self.input?.frame = CGRectMake(0,SCREEN_HEIGHT - 44,SCREEN_WIDTH,44)
            //所有的动作都在delegate中
            self.input?.delegate = self
            self.view.addSubview(self.input!)
            //当发表联系时，因马上出现键盘
            self.input?.inputTextView?.becomeFirstResponder()
        }
        if self.layView == nil{
            self.layView = UIView(frame: self.view.frame)
            self.layView?.backgroundColor = UIColor.grayColor()
            self.layView?.alpha = 0
            let tap = UITapGestureRecognizer(target: self, action: "tapInputView")
             self.layView?.addGestureRecognizer(tap)
            //将某个界面插入到另外一个界面下
           self.view.insertSubview(self.layView!, belowSubview: self.input!)
        }
        self.layView?.hidden = false
    }

为layView添加点击事件当一点击时键盘消失

func tapInputView() {
        //当点击这个layView的时候 键盘就消失
        self.input?.inputTextView?.resignFirstResponder()
    }

当加入inputView的时候都会触发键盘的出现和消失所以这个第三方库已经为我们添加了这方面的通知

//实现inputView的delegate
    //当文本高度发生变化时，整个键盘向上移动
    func textViewHeightDidChange(height: CGFloat) {
        //输入框的高度加10 并且输入框向上已 改变bottom 
       self.input?.height = height + 10
       self.input?.bottom = SCREEN_HEIGHT - CGFloat(self.keyBoardHeight)
    }
     //在inputView中，点击评论的时候 触发的动作
    func publishButtonDidClick(button: UIButton!) {
        //加上进度的提示
        ProgressHUD.show("")
        //传到leanCloud的后台
        let object = AVObject(className: "discuss")
        object.setObject(self.input?.inputTextView?.text, forKey: "text")
        object.setObject(AVUser.currentUser(), forKey: "user")
        object.setObject(self.bookObject, forKey: "BookObject")
        object.saveInBackgroundWithBlock { (success, error) -> Void in
            if success{
                ProgressHUD.showSuccess("评论成功")
            }else{
                ProgressHUD.showError("评论失败")
            }
        }
    }
    func keyboardWillHide(inputView: InputView!, keyboardHeight: CGFloat, animationDuration duration: NSTimeInterval, animationCurve: UIViewAnimationCurve) {
        //当键盘消失时，设置键盘底部的高度为屏幕高度再加上Input的高度
UIView.animateWithDuration(duration, delay: 0, options: .BeginFromCurrentState, animations: { () -> Void in
    self.input?.bottom = SCREEN_HEIGHT + (self.input?.height)!
    self.layView?.alpha = 0.0
    }, completion: {(finish) -> Void in
    //当键盘消失时，将layView再次隐藏起来
        self.layView?.hidden = true
})
    }
    func keyboardWillShow(inputView: InputView!, keyboardHeight: CGFloat, animationDuration duration: NSTimeInterval, animationCurve: UIViewAnimationCurve) {
        //当键盘出现的时候 设置Input的键盘底部的高度离屏幕最上方的距离即设置bottom属性
        //用一个动画来进行设置
        self.keyBoardHeight = Double(keyboardHeight)
        UIView.animateWithDuration(duration, delay: 0, options: .BeginFromCurrentState, animations: { () -> Void in
            self.input?.bottom = SCREEN_HEIGHT - keyboardHeight
            //背景界面的透明度
            self.layView?.alpha = 0.2
            }) { (finish) -> Void in
                
        }
    }

SDWebImage主要是imageView的扩展，他支持可以从url进行缓存，多线程的加载，不会阻塞主线程不需要继承相关的协议

//图片加载 还有默认的图片
        self.bookTitleView?.cover?.sd_setImageWithURL(NSURL(string: (coverFile?.url)!), placeholderImage: UIImage(named: "Cover"))

MJRefresh主要是tableView的上拉加载和下拉刷新的时候可以使用

注册初始化

//上拉加载 下拉刷新
        self.tableView?.mj_header = MJRefreshNormalHeader(refreshingTarget: self, refreshingAction: "headerReFresh")
        self.tableView?.mj_footer = MJRefreshBackFooter(refreshingTarget: self, refreshingAction: "footerReFresh")

func headerReFresh() {
        //查询条件
        let quary = AVQuery(className: "discuss")
        //倒序排序
        quary.orderByAscending("createdAt")
        //表头加载的时候只需20个即可 不需要跳过已有的
        quary.limit = 20
        quary.skip = 0
        quary.whereKey("user", equalTo: AVUser.currentUser())
        quary.whereKey("BookObject", equalTo: self.bookObject)
        //将指针传回
       quary.includeKey("user")
       quary.includeKey("BookObject")
       quary.findObjectsInBackgroundWithBlock { (results, error) -> Void in
        self.tableView?.mj_header.endRefreshing()
        self.dataArray.removeAllObjects()
        self.dataArray.addObject(results)
        self.tableView?.reloadData()
        }
    }
    func footerReFresh() {
        //查询条件
        let quary = AVQuery(className: "discuss")
        //倒序排序
        quary.orderByAscending("createdAt")
        //表尾加载的时候也需要20个 但需要跳过已经加载的
        quary.limit = 20
        quary.skip = self.dataArray.count
        quary.whereKey("user", equalTo: AVUser.currentUser())
        quary.whereKey("BookObject", equalTo: self.bookObject)
        //将指针传回
        quary.includeKey("user")
        quary.includeKey("BookObject")
        quary.findObjectsInBackgroundWithBlock { (results, error) -> Void in
            self.tableView?.mj_footer.endRefreshing()
            //self.dataArray.removeAllObjects()
            self.dataArray.addObject(results)
            self.tableView?.reloadData()
        
    }

progressHUD类似于警告框的作用，感觉以后自己也不用那么麻烦协警告框了

ProgressHUD.show("", interaction:false)
            ProgressHUD.dismiss()
            self.dismissViewControllerAnimated(true, completion: nil)
        }else {
            if error.code == 210{
                ProgressHUD.showError("用户名或密码错误")
            }else if error.code == 211{
                ProgressHUD.showError("不存在该用户")
            }else if error.code == 216{
                ProgressHUD.showError("未验证邮箱")
            }else if error.code == 1{
                ProgressHUD.showError("操作频繁")
            }else {
                ProgressHUD.showError("登陆失败")

XKeyBoard主要是用在一些当问文字处理的时候要出现键盘随后键盘的遮挡问题

其实也是一个通知的机制首先注册通知

//注册键盘出现和消失
        XKeyBoard.registerKeyBoardHide(self)
        XKeyBoard.registerKeyBoardShow(self)

随后实现通知当键盘出现的时候和键盘消失的时候

//键盘遮挡
    func keyboardWillHideNotification(notifacition:NSNotification) {
        
    self.textView?.contentInset = UIEdgeInsetsMake(0, 0,0, 0)
    }
    func keyboardWillShowNotification(notifacition:NSNotification) {
           //返回键盘的大小
        let rect = XKeyBoard.returnKeyBoardWindow(notifacition)
        self.textView?.contentInset = UIEdgeInsetsMake(0, 0, rect.size.height, 0)
    }

}

func keyboardWillHideNotification(notifacition:NSNotification) {
        UIView.animateWithDuration(0.3) { () -> Void in
            self.topLayout.constant = 0
            //加载新的约束
            self.view.layoutIfNeeded()
            
        }
    }
    func keyboardWillShowNotification(notifacition:NSNotification) {
        //做一个动画
        UIView.animateWithDuration(0.3) { () -> Void in
            self.topLayout.constant = -200
            //加载新的约束
            self.view.layoutIfNeeded()
        }
        
    }

IGLDropDownMenu主要是下滑的时候的一个动画的效果实现协议IGLDropDownMenuDelegate

定义两个menu

var dropDownMenu1:IGLDropDownMenu?
    var dropDownMenu2:IGLDropDownMenu?

</pre><pre code_snippet_id="1589511" snippet_file_name="blog_20160226_18_9938298" name="code" class="plain">  self.initDropArray()
        self.createDropMenu(self.literatureArray1, array2: self.literatureArray2)

将数组初始化为这个menu的元素

func createDropMenu(array1:Array<NSDictionary>,array2:Array<NSDictionary>){
        let dropDownItem1 = NSMutableArray()
        for var i = 0;i<array1.count;i++ {
            let dict = array1[i]
            let item = IGLDropDownItem()
            item.text = dict["title"] as? String
            dropDownItem1.addObject(item)
        }
        
        let dropDownItem2 = NSMutableArray()
        for var i = 0;i<array2.count;i++ {
            let dict = array2[i]
            let item = IGLDropDownItem()
            item.text = dict["title"] as? String
            dropDownItem2.addObject(item)
        }
        //重绘的操作
        self.dropDownMenu1?.removeFromSuperview()
        self.dropDownMenu1 = IGLDropDownMenu()
        self.dropDownMenu1?.menuText = "点我，展开详细列表"
        self.dropDownMenu1?.menuButton.textLabel.adjustsFontSizeToFitWidth = true
        self.dropDownMenu1?.menuButton.textLabel.textColor = setColor(38, g: 82, b: 67)
        self.dropDownMenu1?.paddingLeft = 15
        self.dropDownMenu1?.delegate = self
        //动画
        self.dropDownMenu1?.type = .Stack
        self.dropDownMenu1?.itemAnimationDelay = 0.1
        self.dropDownMenu1?.gutterY = 5
        self.dropDownMenu1?.dropDownItems = dropDownItem1 as [AnyObject]
        self.dropDownMenu1?.frame = CGRectMake(20, 150, SCREEN_WIDTH/2-30, (SCREEN_HEIGHT-200)/7)
        self.view.addSubview(self.dropDownMenu1!)
        self.dropDownMenu1?.reloadView()
        self.dropDownMenu2?.removeFromSuperview()
        self.dropDownMenu2 = IGLDropDownMenu()
        self.dropDownMenu2?.menuText = "点我，展开详细列表"
        self.dropDownMenu2?.menuButton.textLabel.adjustsFontSizeToFitWidth = true
        self.dropDownMenu2?.menuButton.textLabel.textColor = setColor(38, g: 82, b: 67)
        self.dropDownMenu2?.paddingLeft = 15
        self.dropDownMenu2?.delegate = self
        self.dropDownMenu2?.type = .Stack
        self.dropDownMenu2?.itemAnimationDelay = 0.1
        self.dropDownMenu2?.gutterY = 5
        self.dropDownMenu2?.dropDownItems = dropDownItem2 as [AnyObject]
        self.dropDownMenu2?.frame = CGRectMake(SCREEN_WIDTH/2+10, 150, SCREEN_WIDTH/2-30, (SCREEN_HEIGHT-200)/7)
        self.view.addSubview(self.dropDownMenu2!)
        self.dropDownMenu2?.reloadView()
        
    }
    //dropDownMenu的delegate
    func dropDownMenu(dropDownMenu: IGLDropDownMenu!, selectedItemAtIndex index: Int) {
        if dropDownMenu == self.dropDownMenu1 {
            let item = self.dropDownMenu1?.dropDownItems[index] as? IGLDropDownItem
            self.detailType = (item?.text)!
            self.dropDownMenu2?.menuButton.text = self.detailType
        }else{
            let item = self.dropDownMenu2?.dropDownItems[index] as? IGLDropDownItem
            self.detailType = (item?.text)!
            self.dropDownMenu1?.menuButton.text = self.detailType
        }
    }
    
    
}

AKSegmentedControl主要是选择栏的加强版个人认为，这里是和上面的dropMenu联合使用的是做一个动画，所以在有些工程中，可以不用的

var segmentController1:AKSegmentedControl?
    var segmentController2:AKSegmentedControl?

//初始化segment
    func initSegment() {
        let buttonArray1 = [
            ["image":"ledger","title":"文学","font":MY_FONT],
            ["image":"drama masks","title":"人文社科","font":MY_FONT],["image":"aperture","title":"生活","font":MY_FONT],
        ]
        let buttonArray2 = [
            ["image":"atom","title":"经管","font":MY_FONT],
            ["image":"alien","title":"科技","font":MY_FONT],
            ["image":"fire element","title":"网络流行","font":MY_FONT],
        ]
        self.segmentController1 = AKSegmentedControl(frame: CGRectMake(10,50,SCREEN_WIDTH - 20,37))
        self.segmentController1?.initButtonWithTitleandImage(buttonArray1)
        self.view.addSubview(segmentController1!)
        self.segmentController2 = AKSegmentedControl(frame: CGRectMake(10,110,SCREEN_WIDTH - 20,37))
        self.segmentController2?.initButtonWithTitleandImage(buttonArray2)
        self.view.addSubview(self.segmentController2!)
        segmentController1?.addTarget(self, action: "segmentControllerAction:", forControlEvents: .ValueChanged)
        segmentController2?.addTarget(self, action: "segmentControllerAction:", forControlEvents: .ValueChanged)
        
    }
    func segmentControllerAction(segment:AKSegmentedControl){
        let index = segment.selectedIndexes.firstIndex
        if segment == self.segmentController1{
            //把2的点击效果取消掉
            self.segmentController2?.setSelectedIndex(3)
        }else{
            self.segmentController1?.setSelectedIndex(3)
            
        }
        self.type = ((segment.buttonsArray[index]) as! UIButton).currentTitle!
        if self.dropDownMenu1 != nil {
            self.dropDownMenu1?.resetParams()
        }
        if self.dropDownMenu2 != nil {
            self.dropDownMenu2?.resetParams()
        }
        
        switch (index){
        case 0:
            self.createDropMenu(self.literatureArray1, array2: self.literatureArray2)
            break
        case 1:
            self.createDropMenu(self.humanitiesArray1, array2: self.humanitiesArray2)
            break
        case 2:
            self.createDropMenu(self.livelihoodArray1, array2: self.livelihoodArray2)
            break
        case 3:
            self.createDropMenu(self.economiesArray1, array2: self.economiesArray2)
            break
        case 4:
            self.createDropMenu(self.technologyArray1, array2: self.technologyArray2)
            break
        case 5:
            self.createDropMenu(self.NetworkArray1, array2: self.NetworkArray2)
            break
        default:
            break
        }
        
    }

JVFloatTextField主要应该是能够使textField更加美观吧个人认为

var BookName:JVFloatLabeledTextField?
    
    var BookEditor:JVFloatLabeledTextField?

self.BookName = JVFloatLabeledTextField(frame: CGRectMake(128,8+40,SCREEN_WIDTH-128-15,30))
        self.BookEditor = JVFloatLabeledTextField(frame: CGRectMake(128,8+70+40,SCREEN_WIDTH-128-15,30))
        
        self.BookName?.placeholder = "书名"
        self.BookEditor?.placeholder = "作者"
        
        self.BookName?.floatingLabelFont = UIFont(name: MY_FONT, size: 14)
        self.BookEditor?.floatingLabelFont = UIFont(name: MY_FONT, size: 14)

LDXScore主要是一个加星星的一个评分的view吧

self.Score = LDXScore(frame: CGRectMake(100,10,100,22))
        //是否可以编辑
        self.Score?.isSelect = true
        self.Score?.normalImg = UIImage(named:"btn_star_evaluation_normal")
        self.Score?.highlightImg = UIImage(named: "btn_star_evaluation_press")
        self.Score?.max_star = 5
        //一出来就是5颗
        self.Score?.show_star = 5

可以把score读出来应show_Star

self.Score?.show_star

VPimagePicker主要是图片的裁剪继承协议VPImageCropperDelegate

func getImageFromPicker(image: UIImage) {
        let CropVC = VPImageCropperViewController(image: image, cropFrame: CGRectMake(0,100,SCREEN_WIDTH,SCREEN_WIDTH * 1.273), limitScaleRatio: 3)
        CropVC.delegate = self
        self.presentViewController(CropVC, animated: true, completion: nil)
    
    }

func imageCropper(cropperViewController: VPImageCropperViewController!, didFinished editedImage: UIImage!) {
        self.BookTitle?.BookCover?.setImage(editedImage, forState: .Normal)
        cropperViewController.dismissViewControllerAnimated(true, completion: nil)
    }
    func imageCropperDidCancel(cropperViewController: VPImageCropperViewController!) {
       cropperViewController.dismissViewControllerAnimated(true, completion: nil)
    }

主要就是这么一些有补足以后再加，就这么多了
