布局如下：（重点讲本地通知）
本地notification所使用的对象是uilocalnotification，uilocalnotification的属性涵盖了所有处理notification需要的内容。uilocalnotification的属性有firedate、timezone、repeatinterval、repeatcalendar、alertbody、 alertaction、hasaction、alertlaunchimage、applicationiconbadgenumber、 soundname和userinfo。
1.首先要明白模拟器和真机的区别：模拟器不会有音频提示，另外就是没有检测允许接受通知，所以我补充一下几点：
1.添加监测通知：
if ([uiapplication instancesrespondtoselector:@selector(registerusernotificationsettings:)]){
[application registerusernotificationsettings:[uiusernotificationsettings settingsfortypes:uiusernotificationtypealert|uiusernotificationtypebadge|uiusernotificationtypesound categories:nil]];
}
上代码：
#import "viewcontroller.h"
#import "detailviewcontroller.h"
@interface viewcontroller ()
@property (weak, nonatomic) iboutlet uibutton *schedule;
@property (weak, nonatomic) iboutlet uibutton *unschedule;
@end
@implementation viewcontroller
- (void)viewdidload {
[super viewdidload];
// do any additional setup after loading the view, typically from a nib.
}
// 调度通知
- (ibaction)schedule:(uibutton *)sender {
// 1.创建通知
uilocalnotification *ln = [[uilocalnotification alloc]init];
if (ln) {
// 设置时区
ln.timezone = [nstimezone defaulttimezone];
// 通知第一次发出的时间
ln.firedate = [[nsdate date]datebyaddingtimeinterval:5];
// 2.设置通知属性
ln.soundname = @"click.wav"; // 音效文件名
// 通知的具体内容
ln.alertbody = @"重大新闻：小韩哥的博客又更新了，赶快进来看看吧！....";
// 锁屏界面显示的小标题，完整标题：（“滑动来”＋小标题）
ln.alertaction = @"查看新闻吧";
// 设置app图标数字
ln.applicationiconbadgenumber = 10;
// 设置app的额外信息
ln.userinfo = @{
@"icon":@"text.png",
@"title":@"重大新闻",
@"time":@"2016-02-28",
@"body":@"重大新闻：小韩哥的博客又更新了，赶快进来看看吧！"
};
// 设置重启图片
ln.alertlaunchimage = @"101339g76j7j9t2zgzdvkj.jpg";
// 设置重复发出通知的时间间隔
// ln.repeatinterval = nscalendarunitminute;
// 3.调度通知（启动任务，在规定的时间发出通知）
[[uiapplication sharedapplication]schedulelocalnotification:ln];
// 直接发出通知没意义
// [[uiapplication sharedapplication]presentlocalnotificationnow:ln];
}
- (ibaction)noschedule:(uibutton *)sender
{
// [[uiapplication sharedapplication]cancelalllocalnotifications];
// 已经发出且过期的通知会从数组里自动移除
nsarray *notes = [uiapplication sharedapplication].scheduledlocalnotifications;
nslog(@"%@",notes);
- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(uilocalnotification *)note
detailviewcontroller *detailvc = segue.destinationviewcontroller;
detailvc.userinfo = note.userinfo;
2.通知详情页面设置基本属性：
.h
#import <uikit/uikit.h>
@interface detailviewcontroller : uiviewcontroller
@property (nonatomic, strong) nsdictionary *userinfo;
.m
@interface detailviewcontroller ()
@property (weak, nonatomic) iboutlet uilabel *userinfocontent;
@implementation detailviewcontroller
self.userinfocontent.text = self.userinfo[@"body"];
- (void)setuserinfo:(nsdictionary *)userinfo
_userinfo = userinfo;
3.didfinishlaunchingwithoptions 实时监测：
- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {
//注册本地通知
if ([uiapplication instancesrespondtoselector:@selector(registerusernotificationsettings:)]){
[application registerusernotificationsettings:[uiusernotificationsettings settingsfortypes:uiusernotificationtypealert|uiusernotificationtypebadge|uiusernotificationtypesound categories:nil]];
// nslog(@"-----didfinishlaunchingwithoptions---");
uilabel *label = [[uilabel alloc]init];
label.frame = cgrectmake(0, 64, 320, 100);
label.backgroundcolor = [uicolor redcolor];
label.font = [uifont systemfontofsize:11];
label.numberoflines = 0;
label.textcolor = [uicolor whitecolor];
label.text = [launchoptions description];
[[[self.window.rootviewcontroller.childviewcontrollers firstobject] view]addsubview:label];
uilocalnotification *note = launchoptions[uiapplicationlaunchoptionsurlkey];
if (note) {
label.text = @"点击本地通知启动的程序";
}else{
label.text = @"直接点击app图标启动的程序";
self.label = label;
return yes;
/**
* 当用户点击本地通知进入app的时候调用（app当时并没有被关闭）
* 若app已关闭不会被调用此方法
*/
- (void)application:(uiapplication *)application didreceivelocalnotification:(uilocalnotification *)notification
self.label.text = @"点击通知再次回到前台";
viewcontroller *homevc = [self.window.rootviewcontroller.childviewcontrollers firstobject];
// [homevc performseguewithidentifier:@"tohome" sender:notification];
[homevc performseguewithidentifier:@"tohome" sender:notification];
三种情况展示：（重要）
1.程序运行在后台
