提问by tinln
Like I said, I add a UIButton in Interface Builder, I want add a UILabel、UIImageView as the button's subviews, but I can't add any object on it in IB. IS anybody know how to do this? Thank you very much.
就像我说的，我在Interface Builder中添加了一个UIButton，我想添加一个UILabel、UIImageView作为按钮的子视图，但是在IB中我无法在其上添加任何对象。有人知道怎么做吗？非常感谢。
I can use code to achieve that, but I want achieve it in IB, so I can use it in any class I want.
我可以使用代码来实现它，但我想在 IB 中实现它，所以我可以在我想要的任何类中使用它。

I have done this before by adding a UIView (instead of the UIButton) then add the UIButton and UILabel to the UIView. The tap from the UIButton still works and you have a label too. You can also add anything else like this.
我之前通过添加 UIView（而不是 UIButton）然后将 UIButton 和 UILabel 添加到 UIView 来完成此操作。UIButton 的点击仍然有效，您也有一个标签。您还可以添加任何其他类似内容。

I normally achieve this by
我通常通过
- Create a new UIView in Interface Builder and set it to be the same size and location that you want your button to have
- Add your subviews to that UIView
- Set the UIView's class to UIButton in the Indentity Inspector
- 在 Interface Builder 中创建一个新的 UIView 并将其设置为您希望按钮具有的相同大小和位置
- 将您的子视图添加到该 UIView
- 在 Indentity Inspector 中将 UIView 的类设置为 UIButton
Your UIView now works exactly like a UIButton
你的 UIView 现在就像一个 UIButton

instead of UIButton, add the UILabel and UIImageView to UIView and then add a tap action to it.
代替 UIButton，将 UILabel 和 UIImageView 添加到 UIView，然后向其添加点击操作。

it's easy to change make a highlighted color effect, use the following code:
很容易改变使突出显示的颜色效果，使用以下代码：
- (void) onViewTap:(id)sender
{
[UIView animateWithDuration:0.1
delay:0
options:UIViewAnimationOptionCurveEaseOut
animations:^{
_view.backgroundColor = [UIColor blueColor];
}
completion:^(BOOL finished){
_view.backgroundColor = [UIColor whiteColor];
}];
//write tap actions below
}
- (void)viewDidLoad
{
_view.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onViewTap:)];
[_view addGestureRecognizer:tap];
}
