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：
