Objective C

Post API with parameters and validate with url to navigate if json
response key with status:"success"

NSString *string= [NSString stringWithFormat:@"url?uname=%@&pass=%@&uname_submit=Login",self.txtUsername.text,self.txtPassword.text];
    NSLog(@"%@",string);
    NSURL *url = [NSURL URLWithString:string];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPMethod:@"POST"];
    NSURLResponse *response;
    NSError *err;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
    NSLog(@"responseData: %@", responseData);
    NSString *str = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
    NSLog(@"responseData: %@", str);
        NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData
                                                         options:kNilOptions
                                                           error:nil];
    NSDictionary* latestLoans = [json objectForKey:@"status"];
    NSString *str2=[NSString stringWithFormat:@"%@", latestLoans];
    NSString *str3=@"success";
    if ([str3 isEqualToString:str2 ])
    {
        [self performSegueWithIdentifier:@"move" sender:nil];
        NSLog(@"successfully.");
    }
    else
    {
        UIAlertController *alert= [UIAlertController
                                 alertControllerWithTitle:@"Try Again"
                                 message:@"Username or Password is Incorrect."
                                 preferredStyle:UIAlertControllerStyleAlert];
        UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
                                                   handler:^(UIAlertAction * action){
                                                       [self.view endEditing:YES];
                                                   }
                             ];
        [alert addAction:ok];
        [[UIView appearanceWhenContainedIn:[UIAlertController class], nil] setTintColor:[UIColor redColor]];
        [self presentViewController:alert animated:YES completion:nil];
        [self.view endEditing:YES];
      }

JSON Response : {"status":"success","user_id":"58","user_name":"dilip","result":"You have been logged in successfully"} Working code
