在自定義中出現錯誤的值uitableViewCell

Question

大家好我正在實現一個聊天Messenger。我面臨着一個奇怪的情況。我有一個自定義的tableview單元格，當我正常滾動時，它工作得非常好。但是，如果我像一個瘋狂的男人滾動非常快，用戶的圖像混合。我不能把數字放在什麼可以是任何幫助夥伴和thx的原因提前

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    UIColor *rung;

您應該正確使用單元格的重用。你有代碼片段：

if ([message.AttendeeID isEqualToString:[HMMainManager getSharedInstance].currentMeeting.strAttendeeID]) { 
      cell.imgThumbUserPic.image = [MainManager getSharedInstance].userManager.userImage; 
     } 

你有沒有處理其他變種。你應該在任何情況下設置用戶圖片

if ([message.AttendeeID isEqualToString:[HMMainManager getSharedInstance].currentMeeting.strAttendeeID]) { 
      cell.imgThumbUserPic.image = [MainManager getSharedInstance].userManager.userImage; 
     } else { 
       cell.imgThumbUserPic.image = nil; //or set it with another image 
}
