- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    
    for (UIView *view in self.subviews) {

        CGPoint viewP = [self convertPoint:point toView:view];
        
        if ([view pointInside:viewP withEvent:event]) {
            return view;
        }
    }
    return [super hitTest:point withEvent:event];
}

其中Btn就是在self上超出的控件
