檢測向左滑動的單元格中的tableView

我試圖發現左輕掃，在開始所以加入到我的tableview：檢測向左滑動的單元格中的tableView

//swipe left 
     UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self 
                         action:@selector(leftSwipe:)]; 
     [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)]; 
     [self.tableView addGestureRecognizer:recognizer];

，然後檢測細胞本身具有：

- (void)leftSwipe:(UISwipeGestureRecognizer *)gestureRecognizer 
{ 

     CGPoint location = [gestureRecognizer locationInView:self.tableView]; 
     NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location]; 
     UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath]; 
     //show some menu in the cell position(its cell.frame) 
}

它只有在桌面視圖沒有向下滾動的情況下才有效，這意味着在向下滾動之後，我檢測到的檢測位置是錯誤的，因此如果我嘗試添加一些側面菜單，它沒有定位正確。

如果我在開始時檢查這個權利，不滾動，它很好。

這是爲什麼？

SwTableviewCell實現了可滑動的內容視圖。這將幫助你在單元格https://github.com/CEWendel/SWTableViewCell上添加滑動條 – vijeesh

已解決。當我添加視圖時，我將它放在視圖中，而不是放在tableView中，因此位置出錯，因爲它們是相對於滾動器計算的，而不是它自己的視圖。

將菜單添加到tableView，把它放在正確的地方。
