UITableView的父類視圖UIView上添加tap手勢匾荆，tableview的點擊事件失效俯在。
解決問題：
給父視圖添加delegate：UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
NSLog(@"%@",touch.view);
if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {
return NO;
}
return YES;
}
