Question

I am in the process of creating an application. In the main ViewController I have created the menu. But I want to have a login screen (UIView) to appear before the menu is visible.

But because the menu loads as soon as I run the application I have decided to create another UIView controller and have that loaded on top of the main ViewController.

Therefore at the end of my main ViewController viewDidLoad I have added the following code to open on top of that view the login view

LoginPageView *loginPageView = [[LoginPageView alloc] initWithNibName:@"LoginPageView" bundle:nil];
loginPageView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:loginPageView animated:YES];  

As I know the purpose of that code is to present another view, but unfortunately the login view does not appear. Only the main ViewController load.
Can anyone help me on that? Have you realised what exactly I want?

Thanks a lot

In the viewDidLoad method, the view exists, but there is no guarantee that the view is already part of the view hierarchy of your application. In fact, almost ain’t.

What you can try is take that code in the viewWillAppear: or viewDidAppear:.
