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];
