How to get touches when parent view has userInteractionEnabled set to NO in iOS

开发者_如何学编程When the parent view has userInteractionEnabled=NO, its subviews will not accept touch events even if their userInteractionEnabled property is set to YES.

Is there any way to still get touch events in subviews?

To get a view to let touches pass-through but give its subviews handle touches, let userInteractionEnabled on that view to YES and, instead, use this snippet:

-(id)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    id hitView = [super hitTest:point withEvent:event];
    if (hitView == self) return nil;
    else return hitView;
}

Swift solution- You need to have a custom view class for the parent view and add the following code to it. Please keep the parent view's user-interactions enabled.

I hope the following code will help you.

class MyCustomParentView: UIView {    
    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        let hitView = super.hitTest(point, with: event)
        if hitView == self {
            return nil
        } else {
            return hitView
        }
    }
}

Setting the parent view's userInteractionEnabled property to NO also implicitly sets its subviews userInteractionEnabled properties to NO as well. I don't know of a way to get touch events to the subview using the approach that you have described, but perhaps you could create a view that simply overlays the views that you want users to interact with, but is not the parent of those views.

A work around would be to disable the userinteraction of buttons etc to nil rather than disabling the user interaction of the whole parent view
