【COCOA(MAC) APPLICATION 開發系列之二】總結一些常用控件以及簡單在自定義VIEW上繪制字元串

上一篇已經對于xib與控件之間的關系都大緻介紹了；

那麼本篇不再詳細解釋如何如何連接配接控件以及控件代碼等，直接給出代碼以及需要注意的簡單介紹下，便于童鞋們使用時可以給與參考：

1. 首先建立一個myview類，繼承nsview，如下：

#import <cocoa/cocoa.h>

@interface myview : nsview

//  myview.m

#import "myview.h"

@implementation myview

- (id)initwithframe:(nsrect)frame

{

    self = [super initwithframe:frame];

    if (self) {

        // initialization code here.

    }

    return self;

}

- (void)drawrect:(nsrect)dirtyrect

    nsstring * str =@"myview   --by himi";

    //屬性包裝設定

    nsmutabledictionary *dic = [nsmutabledictionary dictionary];

    //設定字型樣式

    [dic setobject:[nsfont fontwithname:@"times" size:14] forkey:nsfontattributename];

    //設定字型顔色

    [dic setobject:[nscolor redcolor] forkey:nsforegroundcolorattributename];

    //繪制

    [str drawatpoint:nsmakepoint(50, 50) withattributes:dic];

代碼很easy了解，不在贅述啦～

下面我們看一些基礎常用控件：

//  appdelegate.h

//  created by himi on 12-6-3.

@interface appdelegate : nsobject <nsapplicationdelegate,nstabviewdelegate>

    iboutlet nstextfield *nfcount;

    iboutlet nsview *view ;

    iboutlet nsbutton *btn;

    iboutlet nspopupbutton *popbtn;

    iboutlet nssegmentedcontrol * nsc;

    iboutlet nsform *nform;

    iboutlet nsmatrix * ms;

    iboutlet nsstepper * nsp;

    iboutlet nstabview *tbview;

    iboutlet nscolorwell * nswell;

    iboutlet myview * myview;

-(ibaction)btnpress:(id)sender;

@property (assign) iboutlet nswindow *window;

//  appdelegate.m

@implementation appdelegate

@synthesize window = _window;

- (void)applicationdidfinishlaunching:(nsnotification *)anotification

    //------綁定delegate

    [tbview setdelegate:self];

-(ibaction)btnpress:(id)sender{

    //------ 處理nsbutton的

    if(btn == sender){

        [myview sethidden:yes];

    //------處理nspopupbutton

    if(popbtn == sender){

        nslog(@"%@",[popbtn itemtitleatindex:0]);

        nslog(@"%@",[popbtn itemtitleatindex:1]);

        nslog(@"%@",[popbtn itemtitleatindex:2]);

    //------處理 nssegmentedcontrol

    if(nsc ==sender){

        nslog(@"%i",[nsc isselectedforsegment:0]);

        nslog(@"%i",[nsc isselectedforsegment:1]);

        nslog(@"%i",[nsc isselectedforsegment:2]);

    //------處理 nsform

    if(nform == sender){

        nslog(@"nsform cell 1 is %@",[[nform cellatindex:0] stringvalue]);

        nslog(@"nsform cell 2 is %@",[[nform cellatindex:1] stringvalue]);

        nslog(@"nsform cell 3 is %@",[[nform cellatindex:2] stringvalue]);

    //------處理nsmatrix

    if(ms == sender){

        nslog(@"nsmatrix is select = %@",[[ms selectedcell] title]);

    //-----處理 nsstepper

    if(nsp == sender){

        nsstring *string = [nsstring stringwithformat:@"%i", (int)[nsp doublevalue]];

        [nfcount setstringvalue:string];

    //-----處理 nswell

    if(nswell == sender){  

        nscolor* color =  [nswell color];

        nslog(@"r=%f,g=%f,b=%f",[color greencomponent],[color redcomponent],[color bluecomponent]);

//------處理 tbview

//-(void)tabview:(nstabview *)tabview didselecttabviewitem:(nstabviewitem *)tabviewitem{}

-(void)tabview:(nstabview *)tabview willselecttabviewitem:(nstabviewitem *)tabviewitem{

    if ([tbview indexoftabviewitem:tabviewitem] == 0) {

        nslog(@"view 111");

    }else if ([tbview indexoftabviewitem:tabviewitem] == 1) {

        nslog(@"view 222");
