iphone - 将它链接到 Storyboard 中的某个 View Controller ？

Question

我有一个 Action 需要链接到 Storyboard 中的某个 View 。我目前在下面链接到 Storyboard 的第一个 View 的代码。我如何将它链接到 Storyboard 中的某个 View Controller ？仅供引用 - 此链接来自一个不属于 Storyboard 的 xib 文件，它工作正常。谢谢

  - (IBAction)continueWithoutLoginButtonTouchHandler:(id)sender 
    {

        UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
        UIViewController* initialHelpView = [storyboard instantiateInitialViewController];

        initialHelpView.modalPresentationStyle = UIModalPresentationFormSheet;
        [self presentModalViewController:initialHelpView animated:YES];
    }

我想知道方法:instantiateViewControllerWithIdentifier: 然后识别 Storyboard中的一个 View 是否可行。

 - (IBAction)continueWithoutLoginButtonTouchHandler:(id)sender 
{

    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
   // UIViewController* viewController = [storyboard instantiateInitialViewController];

    UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"RotationVC"];

    viewController.modalPresentationStyle = UIModalPresentationFormSheet;
    [self presentModalViewController:viewController animated:YES];
}

谢谢你的帮助

使用方法:instantiateViewControllerWithIdentifier: 然后识别 Storyboard中的 View 之一:

 - (IBAction)continueWithoutLoginButtonTouchHandler:(id)sender 
{

    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
   // UIViewController* viewController = [storyboard instantiateInitialViewController];

    UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"RotationVC"];

    viewController.modalPresentationStyle = UIModalPresentationFormSheet;
    [self presentModalViewController:viewController animated:YES];
}
