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

Question

I have the following setup.

+- XXXCustomControl : UIControl -------+
| A                                    |
|   +- ContentView -------------------+|
|   |         


        

Answer 1

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:

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