如何从控制器显示和关闭视图？

Question

我只是想显示一个"CreditsView".因此,如果我按下按钮显示信用视图,按确定视图将消失.

我有我的基本控制器和我的信用视图控制器,现在我尝试类似的东西:

- (IBAction)switchToCreditsView:(id)sender {
creditsViewController = [[CreditsViewController alloc] initWithNibName:@"CreditsViewController"];
[self.view addSubview:creditsViewController.view];
//[self presentModalViewController:creditsViewController animated:YES];

}

但如果我按下按钮我的应用程序崩溃了.

Answer 1

要回去,你只需致电:

- (IBAction)switchToBaseView:(id)sender {
    [self dismissModalViewControllerAnimated:YES];
}
