objective-c - 在 tvOS 中呈现 View Controller

Question

我试图在 tvOS 应用程序中呈现一个 View Controller ，但是所包含的代码片段都没有呈现一个。我错过了什么？

代码 1:

 DinoViewController *dinoVC = [[DinoViewController alloc]init];
        dinoVC.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        [self presentViewController:dinoVC animated:YES completion:nil];

代码 2:

   UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
        DinoViewController *dinoVC = [storyboard instantiateInitialViewController];
        dinoVC.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        [self presentViewController:dinoVC animated:YES completion:nil];

Answer 1

找到正确答案:在 tvOS Storyboard中提及 Identifier，(在 iOS 中不一样，)然后实现此代码:

 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *dinoVC = [storyboard instantiateViewControllerWithIdentifier:@"Page1"];
    [self presentViewController:dinoVC animated:YES completion:nil];
