【Cocoa(mac) Application 开发系列之二】总结一些常用控件以及简单在自定义View上绘制字符串

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：
