collectionView 防止cell复用的方法

collectionView 防止cell复用的方法
一:
//在创建collectionView的时候注册cell(一个分区)

UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@“cell" forIndexPath:indexPath];

    for (UIView *view in cell.contentView.subviews) {

        [view removeFromSuperview];

    }



二:

//在cellForItem方法中注册cell(多个分区)

 NSString *identifier=[NSString stringWithFormat:@"%ld%ld",(long)indexPath.section,(long)indexPath.row];
    
    [collect registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:identifier];
    
    UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
    
    for(id subView in cell.contentView.subviews){
        
        if(subView){
            
            [subView removeFromSuperview];
        }
        
    }
