直接从AFNetworking获取NSData，而不是让它转换为UIImage

Question

是否有一个标志，让我得到NSData，而不是让AFNetworking将我的responseData转换成相应的数据类型(UIImage, NSString)?

Answer 1

AFHTTPResponseSerializer将返回原始NSData:

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    [manager GET:... parameters:... 
         success:^(AFHTTPRequestOperation *operation, NSData *responseObject) {} 
         failure:...];

Answer 2

responseData in AFN means (id) - AnyObject.

您可以创建另一个对象。比如NSMutableArray。然后让myArray = responseObject; -例如
