標籤和Imageviews奇怪的行爲在iOS7的自定義單元中

我有一個具有標籤和圖像視圖的自定義單元格。標籤和圖像視圖根據條件顯示。當uitableview滾動時，我的自定義單元格很奇怪。有一個例子，當我滾動一個標籤和imageview的標籤和圖像視圖顯示，但當我滾動回圖像和標籤一個標籤和imageview將消失，有時它重疊另一個imageview和標籤。這是我到目前爲止所嘗試的：標籤和Imageviews奇怪的行爲在iOS7的自定義單元中

static NSString *simpleTableIdentifier = @"JobDetailCell"; 
MTJobDetailCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier forIndexPath:indexPath]; 

if (cell == nil) { 
    cell = [[MTJobDetailCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:simpleTableIdentifier]; 
}

我仍然得到相同的結果。我讀了另一個解決方案，並將我的計算移動到了我的customcell.m文件中。這是在layoutSubviews方法。

NSDictionary *tempDictionary = [NSKeyedUnarchiver unarchiveObjectWithData:[[NSUserDefaults standardUserDefaults] objectForKey:@"IncentivesAndBenefits"]];

這是我的cellForRowAtIndexPath代碼：

     NSData *jsonData = [strIncentives dataUsingEncoding:NSUTF8StringEncoding]; 
     NSError *error; 
     iBenefitsCounter = 0; 

     incentives = [NSJSONSerialization 
         JSONObjectWithData:jsonData 
         options:NSJSONReadingMutableContainers|NSJSONReadingMutableLeaves 
         error:&error]; 

     //TEST 
     //NSLog(@"INCETIVES DICT: %@", incentives); 

     //BOOL iCommission = incentives[@"commission"][@"1"]; 
     NSString *iCommissionDescription = incentives[@"commission"][@"1"]; 
     if([iCommissionDescription isEqualToString:@""] || incentives[@"commission"][@"0"]) 
     { 
      [cell.imgCommissionIncentive setHidden:true]; 
      [cell.lblCommissionIncentive setHidden:true]; 
     } 
     else

     [[NSUserDefaults standardUserDefaults]setObject:[NSKeyedArchiver archivedDataWithRootObject:incentives] forKey:@"IncentivesAndBenefits"]; 
     [[NSUserDefaults standardUserDefaults] synchronize]; 

     return cell; 
    }

我的代碼完全在iOS版8.我真的困惑，爲什麼它不能在iOS的7工作，我一直在這個掙扎自去年周。有人可以幫我。

，你可以嘗試下面的代碼 -

下面寫代碼後

if (cell == nil) { 
    cell = [[MTJobDetailCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:simpleTableIdentifier]; 
} 

for(UIView *view in cell.contentView.subviews){ 
     if ([view isKindOfClass:[UIView class]]) { 
      [view removeFromSuperview]; 
     } 
    }

和

cell.clipsToBounds = YES;

添加所有的UILabel和的UIImage如下

[cell.contentView addSubview:myLabel] ;

嘿感謝您的答覆..但我應該在哪裏[cell.contentView addSubview：myLabel];我只是試過這個解決方案，它現在不顯示任何東西.. –

檢查你的customcell.m你添加self.lblCommissionIncentive或以其他方式發佈完整customcell.m，我會告訴你確切的地方需要添加。 –

標籤和imageviews不是以編程方式創建的。這就是我所做的，我刪除了（UIView *在cell.contentView.subviews中查看）{...}並且標籤和圖像視圖再次顯示.. –

標籤和Imageviews奇怪的行爲在iOS7的自定義單元中
