iPhone的ckeckbox实现方法

-(void)checkboxClick:(UIButton *)btn
{
    btn.selected = !btn.selected;
}


- (void)viewDidLoad {
UIButton *checkbox = [UIButton buttonWithType:UIButtonTypeCustom];
   
    CGRect checkboxRect = CGRectMake(135,150,36,36);
    [checkbox setFrame:checkboxRect];
   
    [checkbox setImage:[UIImage imageNamed:@"checkbox_off.png"] forState:UIControlStateNormal];
    [checkbox setImage:[UIImage imageNamed:@"checkbox_on.png"] forState:UIControlStateSelected];
   
    [checkbox addTarget:self action:@selector(checkboxClick:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:checkbox];   
}

那两个off和on的png图片自己做吧，放到resources目录里。你试试看。
