addSubView to UIButton
提问by Jos
I'm trying to add subviews to a UIButton. This is working fine right now. But the button isn't clickable anymore as soon as I add the subviews.
我正在尝试向 UIButton 添加子视图。这现在工作正常。但是一旦我添加了子视图，该按钮就不再可点击了。
I use the following code:
我使用以下代码：
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(column*100+24, row*80+10, 64, 64);
[button addSubview:asyncImage];
[button addSubview:price];
[button addTarget:self
action:@selector(buttonClicked:)
forControlEvents:UIControlEventTouchUpInside];
The button works again if I cut out the 2 addsubviews. If anyone knows how to fix this it would be great!
如果我删除了 2 个 addsubviews，该按钮将再次起作用。如果有人知道如何解决这个问题，那就太好了！
THNX!!!
THNX！！！

I found a quick solutions. I needed to set the asyncimageview to the following:
我找到了一个快速的解决方案。我需要将 asyncimageview 设置为以下内容：
asyncImage.userInteractionEnabled = NO;
asyncImage.exclusiveTouch = NO;
After this it worked!
在这之后它起作用了！

try:
尝试：
[UIButton buttonWithType:UIButtonTypeCustom];
[UIButton buttonWithType:UIButtonTypeCustom];
instead of:
代替：
[UIButton buttonWithType:UIButtonControlType];
[UIButton buttonWithType:UIButtonControlType];

in the same sitiation i make this action: inherit from UIButton and add all labels and imageview's of button to self, finally put new button to view as last subview and add targets of self button to this last button(also set backgroundColor to clearColor for transparent). now it will be clickable and works fine.
在同一情况下，我执行此操作：从 UIButton 继承并将按钮的所有标签和图像视图添加到 self，最后将新按钮作为最后一个子视图查看，并将 self 按钮的目标添加到最后一个按钮（还将 backgroundColor 设置为 clearColor 为透明）。现在它将是可点击的并且工作正常。

The important thing here is to make sure that userInteractionEnabledwill be set to NO. Fortunately it works immediately for UIImageViewand UILabel(maybe for other subclasses of a UIViewbut those are the most popular subviews added to button) because by default for this classes it is set to NOby default. Unfortunately it is set to YESin UIViewso make sure to change it in that case. Messing around with any other flags shouldn't be necessary. The nature of problem is that many people do not know that default value of this flag is different in subclasses.
这里重要的是确保userInteractionEnabled将设置为NO. 幸运的是，它立即适用于UIImageView和UILabel（可能适用于 a 的其他子类，UIView但这些是添加到按钮的最流行的子视图），因为默认情况下，对于此类，它被设置为NO默认值。不幸的是它被设置为YESinUIView所以一定要在这种情况下改变它。没有必要与任何其他标志混在一起。问题的本质是很多人不知道这个标志的默认值在子类中是不同的。

In Swift, test that is you have your UIButton blocked
在 Swift 中，测试您是否阻止了 UIButton
uibtn.userInteractionEnabled = false
uibtn.exclusiveTouch = false
