ios - AFNetworking 2.0 中 AFImageRequestOperation 的头文件是什么

Question

我正在尝试运行这段代码:

#import "AFNetworking.h"
#import "AFHTTPRequestOperation.h"

AFImageRequestOperation *operation = [[AFImageRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject){
     NSLog(@"%@", operation.responseData); // Data
     NSLog(@"%@", [responseObject class]); // UIImage
 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {}];

但是有这些错误:

Unknown type name AFImageRequestOperation; did you mean AFHTTPRequestOperation? Unknown receiver AFImageRequestOperation; did you mean AFHTTPRequestOperation?

Answer 1

如 this github issue 中所述:

Now, you'd use a regular AFHTTPRequestOperation and set its responseSerializer to an AFImageResponseSerializer object (probably [AFImageResponseSerializer serializer]).

You can read the Migration Guide to know about this whole serialization idea.
