应用程序在通过URL iOS加载图像时崩溃
当出现以下代码时，我的应用程序正在崩溃：应用程序在通过URL iOS加载图像时崩溃,ios,Ios,当出现以下代码时，我的应用程序正在崩溃： [cell.imgViewItem setImageWithURL:imageURL placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { NSLog(@"Finished"); } usingActivityIndicatorStyle:UIAc
[cell.imgViewItem setImageWithURL:imageURL placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
NSLog(@"Finished");
} usingActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
请帮帮我，我正在挣扎。提前感谢。您编写了一个方法sd\u setImageWithURL，该方法被调用，该方法为不支持该调用的UIImageView*调用sd\u cancelCurrentImageLoad。检查实现sd_cancelCurrentImageLoad的源代码及其功能 请在项目中添加SDWebImage框架。
您可以使用cocoapods，在pod文件中使用“pod SDWebImage”。什么是sd\u cancelImageLoadOperationWithKey？他为什么要这样做？尝试添加一些解释。因为他使用的框架不存在。他正在使用SDWebImage加载图像。
