Answer 1

Try this

You need to change as below :

 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];


AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];

manager.requestSerializer=serializer;
manager.responseSerializer.acceptableContentTypes= [NSSet setWithObjects:@"text/html",@"application/json", nil];

Answer 2

Delete line NSLog(@"%@", [error localizedDescription]);. The String which return by [error localizedDescription] is unreadable. See Apple NSError document.

If you want to see the error info, use NSLog(@"%@",error.userInfo[@"NSLocalizedDescription"]);
