UICollectionView uiscrollview等与uislider滑动事件冲突

• (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event;
  //recursively calls -pointInside:withEvent:. point is in the receiver's coordinate system
• (BOOL)pointInside:(CGPoint)point withEvent:(nullable UIEvent *)event;
  // default returns YES if point is in bounds

-(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
    UIView *result = [super hitTest:point withEvent:event];
    if([result isKindOfClass:[UISlider class]] || [result isKindOfClass:[UIButton class]] || [result isKindOfClass:[UISwitch class]]){
        _contentView.scrollEnabled = NO;
    }else{
        _contentView.scrollEnabled = YES;
    }
    return result ;
}
