UILabel UICollectionViewCell在滾動後設置？

Question

在我的代碼，我試圖用UIImage & UIabel在UICollectionViewCell。什麼我做如果在UICollectionViewCell沒有像我想轉移UILabel upwards.So我用標籤的兩幀，並檢查if(UIImageView.image==nil)它顯示效果滾動後？ 怎麼辦？ 這裏是我did-

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView 
     cellForItemAtIndexPath:(NSIndexPath *)indexPath 
{ 

UICollectionViewCell *myCell=(UICollectionViewCell*)[self.view viewWithTag:1]; 
myCell = [collectionView 
          dequeueReusableCellWithReuseIdentifier:@"Cell" 
          forIndexPath:indexPath]; 

UILabel *label=(UILabel*)[myCell viewWithTag:12]; 

UIImageView *collectionViewImage=(UIImageView*)[myCell viewWithTag:11]; 



NSString *collectionViewImageName=[imagesCollectionViewArray objectAtIndex:indexPath.row]; 
collectionViewImage.image=[UIImage imageNamed:collectionViewImageName]; 


if (collectionViewImage.image==nil) { 

[collectionViewImage setBackgroundColor:[UIColor clearColor]]; 
[label setFrame:CGRectMake(35, 73, 309, 54)]; 
label.text=[lableColectionviewArray objectAtIndex:indexPath.row]; 
return myCell; 
}else { 

[label setFrame:CGRectMake(20, 294, 352, 49)]; 
label.text=[lableColectionviewArray objectAtIndex:indexPath.row]; 
return myCell; 

} 

}

嘗試刪除單元格內容查看每個子視圖的CollectionView

代碼 - （UICollectionViewCell *）的CollectionView：（UICollectionView *）的CollectionView cellForItemAtIndexPath：（NSIndexPath *）indexPath

方法調用。

使用

for([UIView *view in cell.contentView.subViews]){ 
    [view removeFromSuperView]; 
    view=nil; 
} 

和替換這行代碼 UICollectionViewCell 了myCell =（UICollectionViewCell）[self.view viewWithTag：1];

With

UICollectionViewCell * myCell = nil;
