How to start an iOS app with a modal view controller already presented without the user being able to see the presenting view?

Question

I've tried many combinations of doing this from the app delegate, the presenting view controller's viewDidLoad, with and without delay, with and without animation.

But either the user can see the presenting view controller for a moment, or the modal doesn't get presented.

How can this be achieved?

Answer 1

Tried code below with storyboard, app starts with modal view controller:

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [self.window makeKeyAndVisible];
    [self.window.rootViewController performSegueWithIdentifier:@"modalSegue" sender:self];

    return YES;
}

Segue configuration from start view controller to modal view controller:

Answer 2

What if your inititalViewController had a picture of your launch image over it.

@property (nonatomic, weak) IBOutlet UIImageView *launchImage;

Set the launch image before the view appears.

- (void)viewWillAppear
{
    self.launchImage.image = [self launchImage];
}

Here's a link to get the launch image.

Then when you present the modal view controller, remove the launch image.

[self presentViewController:vc animated:NO completion:^{
    [self.launchImage removeFromSuperview];
}];
