如何使用AFNetworking 2.0下载图像？

问题描述

显然没有 AFImageRequestOperation ，但只有 AFImageResponseSerializer 而坦率地说我没有得到它或者我可能通过AFNetworking网站看起来太长了...用以前的AFNetworking下载图像就像一个魅力。我不想回到旧的AFnetworking，因为我通过新版本做了几乎所有的东西......任何人？

Appareantly there is no AFImageRequestOperation, but only AFImageResponseSerializer and frankly I don't get it or maybe I'm just looking too long through AFNetworking site... Downloading images with previous AFNetworking was like a charm. I'd hate to go back to older AFnetworking, since I did almost all stuff via the new version... Anyone?

推荐答案

所以你想要2.0这样的东西。

SO you want something like this for 2.0.

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];

正如亚当所提到的，如果你只想把它扔进去，你也可以做下面的事情。一个imageView

As mentioned by Adam you can also do something like the below if you are just wanting to throw it into an imageView

[myImageView setImageWithURL:[NSURL URLWithString:@"http://sitewithimage.com/images/myimage.png"]];
