在iOS7中顯示/隱藏UITableView中的新值？

Question

在練習中我正在做的顯示/隱藏值在UITableView像MXPlayer在android中。 當我添加的值，它應該顯示新在標籤我已經爲自定義單元格。一旦我讀取值，它將顯示在下一個視圖，然後回到列表視圖顯示正確，因爲我例外，但如果我點擊另一個值，它會改變以前的值。

這個代碼，我試了far..help我

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

    static NSString *Identifier = @"ceelll"; 
    customCell *cell =(customCell *) [tableView dequeueReusableCellWithIdentifier:Identifier]; 
    if (cell==nil) { 
     cell=[[[NSBundle mainBundle]loadNibNamed:@"customCell" owner:self options:nil]objectAtIndex:0]; 
    } 

    cell.dataLbl.text=self.listData[indexPath.row]; 
     if([self.checkedData isEqual:indexPath]) 
    { 
     cell.NewHideLbl.text=@"VIEW"; 
     cell.NewHideLbl.textColor=[UIColor greenColor]; 

    } 
    else 
    { 

      cell.NewHideLbl.text=@"NEW"; 
      cell.NewHideLbl.textColor=[UIColor redColor]; 

    } 
    return cell; 
} 
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    if(self.checkedData) 
    { 
     customCell* cell =(customCell*) [tableView cellForRowAtIndexPath:self.checkedData]; 
     cell.NewHideLbl.text=@"NEW"; 
     cell.NewHideLbl.textColor=[UIColor redColor]; 

    } 
    if([self.checkedData isEqual:indexPath]) 
    { 
     self.checkedData = nil; 
    } 
    else 
    { 
     customCell* cell =(customCell*) [tableView 
                   cellForRowAtIndexPath:indexPath]; 
     cell.NewHideLbl.text=@"VIEW"; 
     cell.NewHideLbl.textColor=[UIColor greenColor]; 


     self.checkedData = indexPath; 
    } 
    self.detailObj.tempStr=self.listData[indexPath.row]; 
    [self.navigationController pushViewController:self.detailObj animated:YES]; 
} 

這是學習的目的only..Help我在此先感謝..

簡單的錯誤再次給你相同的名稱，以便其因此您需要更改NEW以查看

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    if(self.checkedData) 
    { 
     customCell* cell =(customCell*) [tableView                cellForRowAtIndexPath:self.checkedData]; 
     // cell.NewHideLbl.text=@"NEW"; here again you are assigning label NEW so its getting new one 
     cell.NewHideLbl.text=@"VIEW"; 
     cell.NewHideLbl.textColor=[UIColor greenColor]; 

    } 
    if([self.checkedData isEqual:indexPath]) 
    { 
     self.checkedData = nil; 
    } 
    else 
    { 
     customCell* cell =(customCell*) [tableView 
                   cellForRowAtIndexPath:indexPath]; 
     cell.NewHideLbl.text=@"VIEW"; 
     cell.NewHideLbl.textColor=[UIColor greenColor]; 


     self.checkedData = indexPath; 
    } 
    self.detailObj.tempStr=self.listData[indexPath.row]; 
    [self.navigationController pushViewController:self.detailObj animated:YES]; 
}
