如何为 iPhone Xcode 创建登录屏幕 [英] how to create login screen for iPhone Xcode

问题描述

我正在尝试学习客观的 c xcode 编程，我有一个小项目要做.首先，我正在尝试做一个简单的登录页面，用户在其中输入用户名和密码.用户名和密码在程序中硬编码.所以没有太多逻辑.但我的问题是，如果登录正确，您如何转发屏幕?

I am trying to learn objective c xcode programming and I have a small project to do. First of all, I am trying to do a simple login page, where user enters username and password. username and password are hardcoded in the program. so there is not much logic. but my problem is, how do you forward the screen if the login is correct?

这是我的代码，

- (IBAction)btn_login_submit:(id)sender {
  if([_txt_username.text isEqual:@"rotanet"] && [_txt_username.text isEqual:@"rotanet"]){
      _lbl_result.text = @"correct";
  }
  else{
      _lbl_result.text = @"incorrect";
  }
}

我正在使用故事板，现在我只有一个视图控制器.我应该添加另一个视图控制器还是其他东西?以及如何从登录跳转到下一页?

I am using storyboard, and now I have only one view controller. Should I add another view controller or something else? and how do I forward to the next page from login?

谢谢

推荐答案

    if([_txt_username.text isEqual:@"rotanet"] && [_txt_username.text isEqual:@"rotanet"]){

          UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];

          ViewController* viewController = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"];

        [self presentModalViewController: viewController animated: YES];
    }
