推荐答案

我只是把我的逻辑。

• 你的视图已被显示4张图片（具有不同形状）因此您需要在 .h 文件中获取4 UIImageView 并且一个 UIView 名称 .h 文件中的 ImgContainerView



• 确保您的所有按钮有相同的操作方法，并为其提供标记的所有按钮。例如，每个按钮的方法名称为

• your view has been display 4 images (with different shape) so you need to take 4 UIImageView in .h file and one UIView name is ImgContainerView in .h file

• make sure that your all button has same action method and give all button to it's tag. for example each button has method name is

- （void）buttonMethodName：（UIButton *）sender

-(void) buttonMethodName:(UIButton *) sender

然后你需要创建一个方法名称，

Then you need to create one method name is,

- （void）setUpimagesByselectedButton ：（int）buttonTag

-(void)setUpimagesByselectedButton:(int) buttonTag

在按钮的动作方法中调用此方法，如

Call this method in button's action method, such like

-(void) buttonMethodName:(UIButton *) sender           
{
  [self setUpimagesByselectedButton:sender.tag]; // pass button's tag as parameter.
}

现在方法中，

-(void)setUpimagesByselectedButton:(int) buttonTag
{
  // first you need to remove all subview of ImgContainerView 
  if(self.ImgContainerView)
  {
    for(UIView *subview in self.ImgContainerView.subviews)
        [subview removeFromSuperview];
    [self.ImgContainerView removeFromSuperview]; self.ImgContainerView = nil;
  }
  // Then re-create  ImgContainerView with background color is white;
  // add all UIImageView as subView of ImgContainerView;
  // and then set FRAME of your UIImageView base on selected button's tag such like.
  if(buttonTag == 1)// for ex. i take 1, here you write your button's tag.
    self.imageView1.frame....
  // create one by one imageView and set it's frame by put condition as above       
  // your UIImageView's contentMode should be  UIViewContentModeScaleAspectFill or UIViewContentModeCenter;
}

当你点击任何按钮时，每次 ImgContainerView 是用它的特殊形状重新创建的。

When you tap any button then each time ImgContainerView is re-created with it's particular shape.
