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

You can subclass your subview, and implement

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    if (!touchedContent) {
        [[self nextResponder] touchesBegan:touches withEvent:event];
    } else {
        [super touchesBegan:touches withEvent:event];
    }
}

You could try overriding the pointInside:withEvent: method in your inner view. This will allow you to return NO when you want to forward touches to the superview:

-(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
    if( /* You have content, and you want to receive touches */){
        return YES;
    }else{
        return NO;
    }
}

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!
