    text
    copied!<p>I am trying to send post request on some url and in body to be only json data (trying to register new user sending json like</p> <pre><code>{ "username": "test", "password": "test", "email": "email@gmail.com" } </code></pre> <p>I have function like </p> <pre><code>-(NSString*) sendPostOnUrl:(NSString*) url withParameters:(NSDictionary*)params{ __block NSString* response = nil; NSError *error; NSURL *u = [NSURL URLWithString:url]; AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL: u]; [httpClient postPath:REGISTER parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { response = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"Request Successful, response '%@'", response); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"[HTTPClient Error]: %@", error.localizedDescription); }]; return response; } </code></pre> <p>where params are NSDictionary with keys username, password and email and values for those keys. Problem is when I send I always in return get null in response (the latest line) but in NSLog I get json response.. I am very new to ios, and it looks to me that I need to sync on some way block with return from function but don't know how, can anybody give me a clue what am I doing wrong ? (params contains all those keys when I try to debug, url is ok, REGISTER is NSString constant)</p>
