AFNetworking 2.0 - 如何下载uiimage异步 [英] AFNetworking 2.0 - How to download uiimage async

问题描述

在使用AFNetworking 2.0的ios中，我如何能够轻松地异步下载远程图像并将其缓存以备将来请求相同的URL？我正在寻找一种方便的方法来接收错误回调和成功的回调。

In ios using AFNetworking 2.0 how can I easily download a remote image asynchronously and cache it for future request of the same url? I'm looking for a convenient way to receive both error callbacks and successful ones.

谢谢

推荐答案

你可以做到

AFHTTPRequestOperation *requestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:urlRequest];
requestOperation.responseSerializer = [AFImageResponseSerializer serializer];
[requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Response: %@", responseObject);
    _imageView.image = responseObject;

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Image error: %@", error);
}];
[requestOperation start];
