UITableView細胞におけるジェスチャーエラー

Question

私はGestureRecognizerの私UITableViewCellに問題がある、私はスワイプ左と右のジェスチャー、タップ＆ホールド2秒のために持っているとテーブルビューのセルにジェスチャーをピンチ、スワイプ、右の次の章のために、前の章放置スワイプ、ピンチ別のビューコントローラにリダイレクトし、テーブルと呼ばれる単一のテーブルビューに実装されている.ALL（サブビュー）を表示するポップアップのために保持2秒。私の問題は、すべてのものは罰金を動作しますが、それはswipeGestureが機能していないにもピンチすることができるstucksテーブルビューでジェスチャーを使用していくつかの長い期間の後です。しかし、私は別のページに移動して戻ってきたとき、それは通常の作業を開始します。そしてそれはまた、いくつかの時間後にstucks。これを解決する方法私のコードはありますか？

ともアクションも非常に遅いです。 私を助けてくださいます。

Answer 1

You add a recognizer every time the routine tableView:cellForRowAtIndexPath: is called, and remove one after a gesture is processed. So after all recognizers (number of them equals number of cells) are removed, the gesture won't be recognized.

Perhaps you should not remove the recognizer in handling routine?

Answer 2

Your gesture recognizers apply to the whole table, yet you add them every time a cell is created!

Instead of adding the gesture recognizers to the whole table every time it creates a cell, try adding them somewhere else. Or if you mean to have the gestures in just cells, try using:

[cell addGestureRecognizer:recognizer];
