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`
