UITapGestureRecognizer 和 UICollectionView/UITableView等点击事件冲突问题

在gestureRecognizer方法中，利用isDescendantOfView来判断当前点击区域是否是collectionView/tableView，若是，则返回NO，忽略该手势的点击事件，否则返回YES。

先添加代理 UIGestureRecognizerDelegate ，再判断触摸点在触摸视图时禁用此 tap 

#pragma mark - UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    if ([touch.view isDescendantOfView:self.collectionView]) {
        return NO;
    }
    return YES;
}
