上一篇已经对于xib与控件之间的关系都大致介绍了；

那么本篇不再详细解释如何如何连接控件以及控件代码等，直接给出代码以及需要注意的简单介绍下，便于童鞋们使用时可以给与参考：

1. 首先创建一个MyView类，继承NSView，如下：

//
//  MyView.h
//  ManyControlTest
//
//  Created by Himi on 12-6-6.
//  Copyright (c) 2012年 Himi. All rights reserved.
//

#import <Cocoa/Cocoa.h>

@interface MyView : NSView
@end

//
//  MyView.m
//  ManyControlTest
//
//  Created by Himi on 12-6-6.
//  Copyright (c) 2012年 Himi. All rights reserved.
//

#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";
    
    //属性包装设置
    NSMutableDictionary *dic = [NSMutableDictionary dictionary];
    
    //设置字体样式
    [dic setObject:[NSFont fontWithName:@"Times" size:14] forKey:NSFontAttributeName]; 
    
    //设置字体颜色
    [dic setObject:[NSColor redColor] forKey:NSForegroundColorAttributeName];
    
    //绘制
    [str drawAtPoint:NSMakePoint(50, 50) withAttributes:dic];
}

@end

代码很easy理解，不在赘述啦～

下面我们看一些基础常用控件：

//
//  AppDelegate.h
//  ManyControlTest
//
//  Created by Himi on 12-6-3.
//  Copyright (c) 2012年 Himi. All rights reserved.
//

#import <Cocoa/Cocoa.h>
#import "MyView.h"

@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;

@end

 

//
//  AppDelegate.m
//  ManyControlTest
//
//  Created by Himi on 12-6-3.
//  Copyright (c) 2012年 Himi. All rights reserved.
//

#import "AppDelegate.h"

@implementation AppDelegate

@synthesize window = _window;

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    //------绑定Delegate
    [tbView setDelegate:self];
}
-(IBAction)btnPress:(id)sender{
    
    //------ 处理NSButton的
    if(btn == sender){
        [myView setHidden:YES];
    }
    
    
    //------处理NSPopUpButton
    if(popBtn == sender){
        NSLog(@"%@",[popBtn itemTitleAtIndex:0]);
        NSLog(@"%@",[popBtn itemTitleAtIndex:1]);
        NSLog(@"%@",[popBtn itemTitleAtIndex:2]);
    }
    
    //------处理 NSSegmentedControl
    if(nsc ==sender){
        NSLog(@"%i",[nsc isSelectedForSegment:0]); 
        NSLog(@"%i",[nsc isSelectedForSegment:1]); 
        NSLog(@"%i",[nsc isSelectedForSegment:2]); 
    }
    
    //------处理 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]); 
    }

    //------处理NSMatrix
    if(ms == sender){
        NSLog(@"NSMatrix is Select = %@",[[ms selectedCell] title]); 
    }

    //-----处理 NSStepper
    if(nsp == sender){
        
        NSString *string = [NSString stringWithFormat:@"%i", (int)[nsp doubleValue]]; 
        [nfCount setStringValue:string];
    }
    
    //-----处理 nsWell 
    if(nsWell == sender){  
        NSColor* color =  [nsWell color];
        NSLog(@"R=%f,G=%f,B=%f",[color greenComponent],[color redComponent],[color blueComponent]); 
    }
}

//------处理 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");
    }
}

@end

 

运行截图如下：
