Try This

NSString *strData = [[NSString alloc] initWithFormat:@"{\"login_provider\": \"IOS\",\"email\": \"%@\",\"password\": \"%@\",\"ios_device_id\": \"1\"}",self.txtEmail.text,self.txtPassword.text];

                NSString *strURL = @"http://capemedics.co.za/Api/user_register/valid_user"];

                NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strURL] cachePolicy:NSURLRequestReloadIgnoringCacheData  timeoutInterval:10];

                [request setHTTPMethod:@"POST"];
                [request setValue: @"YOUR_KEY" forHTTPHeaderField: @"AppSecret"];
                [request setValue: @"application/json" forHTTPHeaderField:@"Content-Type"];
                [request setHTTPBody: [strData dataUsingEncoding:NSUTF8StringEncoding]];

                AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
                op.responseSerializer = [AFJSONResponseSerializer serializer];
                [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
                 {
                     if (responseObject)
                     {
                      }
                  }
                 } failure:^(AFHTTPRequestOperation *operation, NSError *error){
                 }];

                [op start];
