AFNetworking 2.0 setImageWithURLRequest [英] AFNetworking 2.0 setImageWithURLRequest

问题描述

在我当前的一个项目中下载图像时，我正在使用此代码，但它不适用于AFNetworking 2.0。我尝试通过AFImageResponseSerializer进行尝试，但找不到正确的代码。

I'm using this code when downloading images in one of my current projects and it's not working with AFNetworking 2.0. I tried going thru AFImageResponseSerializer but I can't find the right code to use.

[cell.posterImage setImageWithURLRequest:urlRequest placeholderImage:[UIImage imageNamed:@"placeholder.png"] success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
            cell.posterImage.image = image;
        } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
            NSLog(@"Request failed with error: %@", error);
        }];

对AFNetworking 2.0中使用的新代码有何建议？谢谢！

Any suggestions on the new code used in AFNetworking 2.0? Thanks!

推荐答案

我使用以下代码使它起作用：

I made it work using this code:

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

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Image request failed with error: %@", error);
}];
[[NSOperationQueue mainQueue] addOperation:posterOperation];
[posterOperation start];

但是我在使用占位符图像时遇到了另一个问题。有什么想法吗？

But I got into another problem with placeholder images using this. Any ideas?
