在 tvOS 中呈现视图控制器

Question

我试图在 tvOS 应用程序中展示一个视图控制器，但是所包含的代码片段都没有展示一个。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

请试试这个..

 DinoViewController *dinoVC = [[DinoViewController alloc]init];
        dinoVC.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

   [self showViewController:dinoVC sender:nil];

希望这会希望你

Answer 2

找到正确答案：在 tvOS storyboard 中提到 Identifier，（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];
