IOS自訂view——checkbox

============================================================博文原創，轉載請聲明出處電子咖啡(原id藍岩)============================================================IOS中沒有checkbox和radio button ,這一點對於做過android的童鞋會覺得挺無語的，沒關係，我們自己寫一個view來實現自己的單、複選框。首先在你的資源裡面添加2張圖片，一張為按鈕的選中狀態，另一個為沒選中狀態，分別命名：unchecked.png，checked.png，下面上代碼，相信你看得懂。，如有疑問，歡迎留言交流。UICheckBox.h

#import <UIKit/UIKit.h>@interface UICheckBox : UIButton@end

UICheckBox.m

#import "UICheckBox.h"@implementation UICheckBox- (id)initWithFrame:(CGRect)frame{    self = [super initWithFrame:frame];    if (self) {       [self setBackGroundImage];    }    return self;}- (void)setBackGroundImage {    [self setBackgroundImage:[UIImage imageNamed:@"unchecked.png"] forState:UIControlStateNormal];    [self setBackgroundImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateSelected];            [self addTarget:self action:@selector(touchUIInside:) forControlEvents:UIControlEventTouchUpInside];}-(id)initWithCoder:(NSCoder *)aDecoder{    self =  [super initWithCoder:aDecoder];    if (self) {        [self setBackGroundImage];    }    return self;}-(IBAction)touchUIInside:(id)sender{   UICheckBox* cb= (UICheckBox*)sender;    cb.selected = !cb.selected;      }
