是的，在iOs中没有复选框（ - ：
这里，这是我做了一个复选框

  UIButton * checkbox和
 BOOL checkBoxSelected; 
 checkbox = [[UIButton alloc] initWithFrame：CGRectMake（x，y，20,20）
 // 20x20是checckbox你想要的
 //创建2个图像大小20x20，一个空方形和
 //同一个正方形的另一个带有复选标记
 //使用这些新图像创建2个UIImages，然后：
 
 [checkbox setBackgroundImage：[UIImage imageNamed：@notselectedcheckbox.png] 
 forState：UIControlStateNormal]; 
 [checkbox setBackgroundImage：[UIImage imageNamed：@selectedcheckbox.png] 
 forState：UIControlStateSelected]; 
 [checkbox setBackgroundImage：[UIImage imageNamed：@selectedcheckbox.png] 
 forState：UIControlStateHighlighted]; 
 checkbox.adjustsImageWhenHighlighted = YES; 
 [checkbox addTarget .....] 
 [self.view addSubview：checkbox]; 
  

现在在目标方法中执行以下操作：

   - （void）checkboxSelected：（id）sender 
 {
 checkBoxSelected =！checkBoxSelected; / * Toggle * / 
 [checkbox setSelected：checkBoxSelected]; 
} 
  

这是

Yeah, no checkbox for you in iOs (-: Here, this is what I did to create a checkbox

UIButton *checkbox and
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)
// 20x20 is the size of the checckbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget.....]
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

that's it
