Question

我的应用程序在下面出现以下代码时崩溃：

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

以下是日志跟踪：

请帮助我，我正在努力。提前谢谢。

Answer 1

您编写了一个被调用的方法sd_setImageWithURL，该方法为不支持该调用的UIImageView *调用sd_cancelCurrentImageLoad。检查实现sd_cancelCurrentImageLoad的源代码及其功能。

Answer 2

请在您的项目中添加SDWebImage框架。你可以使用cocoapods，在pod文件中使用'pod“SDWebImage”。
