ラベルは別のビューコントローラにナビゲートすると更新が停止します

Question

私はサーバにファイルをアップロードしてラベルにパーセントを表示していますが、ラベルはテーブルのセルにありますが、別のビューに移動すると、我々は

Answer 1

は、メインスレッドでセルを更新するようにしてください..テーブルをスクロールします。ブロックを使用しているときはブロック変数を使用します。アップロードがuploadIndexへのセルのインデックス保存をクリックすると

1. は
2. 、進捗状況を保持する変数を持ってCGFloat _progress、NSIndexPath *uploadIndex。

4. リロードshowProgressViewのセル進歩は変数更新：次に細胞、cell.progressValue = _progressに進捗を更新cellForRowAtIndex、if([indexPath isEqual:uploadIndex])で

    showProgressView:^(float progress, NSString *messageId) { 
         dispatch_async(dispatch_get_main_queue(), ^{ 
          _progress = progress; [self.tableViewChatConv reloadRowsAtIndexPaths:@[uploadIndex] withRowAnimation:UITableViewRowAnimationNone]; 
         } 
        } 
   

5. をブロックします。

Answer 2

はのviewDidLoadでNSTimerを入れてNSTimerのセレクタに動作方法を設定：

およびアクションmethode.gにtabelビューをリロード：[_mytableviewリロード]。
