AFNetworking response failure block is called instead of success block

Question

AFNetworking response failure block is being called when I get status code 200. How can I make the success be called instead?

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://128.199.94.58/test/bt/client_token.php" parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
         self.clientToken = responseObject[@"customerID"];
         NSLog(@"Client Token received.");
     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         // Handle failure communicating with your server
         NSLog(@"Client Token request failed.%@",operation.responseString);
         NSLog(@"error code %ld",(long)[operation.response statusCode]);
     }];

Answer 1

Look at the value of error. It will tell you why the connection failed. "Failure" in this context has nothing to do with the status code. Returning "404" is still a "success." Failure means you were unable to complete the operation.

Answer 2

use acceptableStatusCodes as follows:

 AFHTTPRequestOperationManager *manager =  [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [TimeoutAFJSONRequestSerializer serializer];
NSMutableIndexSet* codes = [[NSMutableIndexSet alloc] init];
[codes addIndex: 200];
manager.responseSerializer.acceptableStatusCodes = codes;

[manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
 {


 } failure:^(AFHTTPRequestOperation *operation, NSError *error)
 {
 }];
