Switch views after a specified time

Question

I am currently developing a landscape app that I would like to have a launch image in. Since launch images do not work in landscape, I want to make my launch image a view, and after about 5 seconds after this view is shown when the app launches, the view will switch to the original first view of the app. How do I do this? I am using storyboards.

I tried using asset catalogs for the launch image and also not using asset catalogs. Both did not work. Then I made a test app. When the only box checked off was portrait the launch image showed perfectly. However when I only checked off landscape left and right it did not work. — msweet168, May 17 '14 at 22:17

Just add a custom view in your application:didFinishLaunchingWithOptions: method.

UIImageView*imageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"your_image.png"]];
[[yourFirstViewController view] addSubview:imageView];
[[yourFirstViewController view] bringSubviewToFront:imageView];

[self.window makeKeyAndVisible];

// Fade out the image
[UIView transitionWithView:self.window 
                  duration:1.0f 
                   options:nil
                animations:^(void)
{ 
    imageView.alpha=0.0f;
} 
                completion:^(BOOL finished)
{
    [imageView removeFromSuperview];
}];

What do you mean by "yourFirstViewController" like the name of the view controller that will appear after the image is shown? – msweet168 May 17 '14 at 22:19
That's literally first view controller that you show. The initial view controller. – Rafał Sroka May 17 '14 at 22:21
Im getting a warning with nil, and a warning and error with both of the yourFirstViewController and also the "view" after it. I still do not know what to put in your first view controller – msweet168 May 17 '14 at 22:24
The view error is "class method +view not found (return type defaults to 'id') – msweet168 May 17 '14 at 22:26
The nil error is: "incompatible pointer to integer conversion sending 'void*' to parameter of type 'UIViewAnimationOptions' – msweet168 May 17 '14 at 22:28
Of course you are getting this errors. You have to modify my code to suit your case. Specify your initial view controller etc. – Rafał Sroka May 17 '14 at 22:30
I did that but what do I do with nil and view – msweet168 May 17 '14 at 22:31

I used a delay to set off a segue programmatically.

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

[self performSelector:@selector(enterthegame) withObject:nil afterDelay:5];
}

-(void)enterthegame{
[self performSegueWithIdentifier: @"tothegame" sender: self];
}

Just make sure that you have a segue and its identifier matches your code. The button the the segue is connected to can be hidden.
