应用程序崩溃，而通过URL的iOS加载图像

-2

我的应用程序的时候才来下面的代码是低于当前崩溃：应用程序崩溃，而通过URL的iOS加载图像

[cell.imgViewItem setImageWithURL:imageURL placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { 
      NSLog(@"Finished"); 
     } usingActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];

下面是日志跟踪：
