Question

我的ViewController中有2个单独的UICollectionView，我试图使用以下代码从URL加载图像。为了缓存图像并以异步方式加载它，我开始通过可可豆荚使用SDWebImage 5.0。但是我的应用程序崩溃，并显示以下消息。我尝试了SDWebImage的早期版本，但仍然遇到此问题。我什至在其他链接标志中添加了-ObjC标志：

libc++abi.dylib: terminating with uncaught exception of type NSException

这是我的UICollectionView代码：

    //loading featured collection data
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 1;
}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    if(collectionView == self.collectionView){
        return _resultArray.count;
    }else{
        return _resultArray.count;
    }
}


- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    if(collectionView == self.collectionView){
        NSString *urlString = [[_resultArray objectAtIndex:indexPath.row] valueForKey:@"url"];
        NSLog(@"%@",urlString);

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

       [cell.photo sd_setImageWithURL:[NSURL URLWithString:urlString]
        placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

        return cell;
    }else{
        NSString *urlString = [[_userArray objectAtIndex:indexPath.row] valueForKey:@"url"];
        NSLog(@"%@",urlString);

        userCell *cell =[collectionView dequeueReusableCellWithReuseIdentifier:@"user" forIndexPath:indexPath];
       [cell.userphoto sd_setImageWithURL:[NSURL URLWithString:urlString]
              placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
        return cell;
    }

}

在UICollectionView中加载图像时SDWebImage 5.0崩溃
