IOS开发

IOS本身没有系统的CheckBox组件，但是实际开发中会经常用到，所以专门写了一个CheckBox控件，直接上代码

效果图：

UICheckBoxButton.h文件如下：
[html]
#import <UIKit/UIKit.h> 
#import "Common.h" 
 
@interface UICheckBoxButton : UIControl 
{         
    UILabel *label;   
    UIImageView *icon;   
    BOOL checked;   
    id delegate;    
}     
@property (retain, nonatomic) id delegate;   
@property (retain, nonatomic) UILabel *label;   
@property (retain, nonatomic) UIImageView *icon;   
 
-(BOOL)isChecked;   
-(void)setChecked: (BOOL)flag;  
@end 

UICheckBoxButton.m文件如下：
[html] 
#import "UICheckBoxButton.h" 
 
@implementation UICheckBoxButton 
@synthesize label,icon,delegate;   
 
- (id)initWithFrame:(CGRect)frame { 
    if ( self = [super initWithFrame: frame])    
    {           
        icon =[[UIImageView alloc] initWithFrame: CGRectMake (0, 0, frame.size.height, frame.size.height)];           
        [self setChecked:NO]; 
        [self addSubview: icon];         
        label =[[UILabel alloc] initWithFrame: CGRectMake(icon.frame.size.width + 7, 0,   
                                                          frame.size.width - icon.frame.size.width - 10,   
                                                          frame.size.height)];   
        label.backgroundColor =[UIColor clearColor];
