You can use another UIView to "hide" the subview. 
*Details : This UIView is the subview's sibling . it has the same size and position of your subview with background color of clear color. 
*Explain: The new UIView will take the touch, and automatically pass it to the superview. 
This way doesn't need to subclass your subview - it's a storyboard solution. Please try this. Have fun!

blocks|key|758391|text|在超级视图中使用这一点，而不需要更改子视图代码(因为子视图可以从其他框架或豆荚中引入)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|758392|-+(UIView+*)hitTest:(CGPoint)point+withEvent:(UIEvent+*)event
{
++++UIView+*view+=+[super+hitTest:point+withEvent:event];

Use this in super view, without changing subviews code (since subviews may be introduced from other frameworks or pods):

<pre><code>- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
 UIView *view = [super hitTest:point withEvent:event];
 if ([view isDescendantOfView:self])
 {
 NSLog(@"touched inside");
 }
 return view;
}

blocks|key|1122076|text|如果您希望处理来自superview的事件(在您的情况下是XXXCustomControl)，而不是内部视图(在您的情况下是ContentView)，您可以在superview中编写以下快速代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1122077|override+func+hitTest(_+point:+CGPoint,+with+event:+UIEvent?)+->+UIView?+{
++++guard+let+view+=+super.hitTest(point,+with:+event)+else+{+return+nil+}

If you want to handle the event from superview(XXXCustomControl in your case) instead of inner view(ContentView in your case), you can write the following swift code in your superview:

<pre><code>override func hitTest(_ point: CGPoint, with event: UIEvent?) -&gt; UIView? {
 guard let view = super.hitTest(point, with: event) else { return nil }
 if view.isDescendant(of: self) {
 // your custom logic
 }
 return view
}
</code></pre>

I have the following setup. 

<pre><code>+- XXXCustomControl : UIControl -------+
| A |
| +- ContentView -------------------+|
| | ||
| | B ||
| | ||
| +---------------------------------+|
+--------------------------------------+ 
</code></pre>

A XXXCustomControl that is a subclass of UIControl. It contains one subview called contentView of type UIView with size that is smaller than the Control's area..
That view has <code>.userInteractionEnabled = YES</code>;

I need that property to have set to YES, because horizontal scrollviews are put inside this once in a while and they need to be scrollable. If the superview (in our case content view would not allow user interaction, this is inherited y the subviews.)
But at the same time this <code>XXXCustomControl</code> need to be tappable when it contains no scrollview in its content view not only in area A but also in area B.

So I have a "conflict of interests" here because I either

1) set the content view to <code>userInteractionEnabled = NO</code>, then I can tap the empty control in the content view area both in A and B, but the scrollviews I will put there won't be scrollable..

2) set the content view to <code>userInteractionEnabled = YES</code> but then, if the Control s empty, I can only tap area A to trigger a touch event.

One idea I came up with is that I set the property to NO by default and when I populate the contentView I set it to yes. when I clear the contentView I set the property back to no. 
Basically I want this to have set to yes all the time, and when it is empty ,force the contentView to pass the touchUpInside event up to its superview.

Is this possible?

How to pass the touch event to superview when userInteractionEnabled = YES?
