Question

I have two xib files. I start with “ViewController.xib” and when the user clicks a button it loads a different xib file named “GamePage.xib”.

The code of the button is:

-(IBAction)startButtonClicked{    
    UIViewController *gamePage = [[UIViewController alloc] initWithNibName:@"GamePage" bundle:nil];
    [self presentViewController:gamePage animated:NO completion:nil];
}

When the button is clicked, the second xib is shown on screen, but its “viewDidLoad” method don’t run…

Why is that?

Answer 1

UIViewController *gamePage = [[UIViewController alloc] initWithNibName:@"GamePage" bundle:nil];

This does not seem correct.

viewDidLoad is probably running but it is viewDidLoad of Apple’s UIViewController. You should use your class instead of UIViewController when you initialize it. In general you should use the class which viewDidLoad you need called.
