Question

Trying to programmatically add a splash image that hangs around for a specified amount of time. I have Default.png already imported into my project, and I see it flicker as the launch image when the simulator launches. I’m not sure how to make Default.png hang around as the splash image.

In AppDelegate.m, inside didFinishLaunchingWithOptions I do the following:

MyViewController *mvc = [[MyViewController alloc] init];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:mvc] autorelease];
[navController setNavigationBarHidden: YES];

MyViewController as you might suspect, is a subclass of UIViewController, and in the loadView method I do the following:

self.mainView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.view = mainView;
mainView.backgroundColor = [UIColor yellowColor];

Then I created SplashScreenViewController, also a subclass of UIViewController, and in the loadView method I do the following:

splashView = [[[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, 480)] autorelease];
splashView.image = [UIImage imageNamed:@"Default.png"];

Finally, back in AppDelegate I have the following after makeKeyAndVisible:

SplashScreenViewController *splashScreen = [[SplashScreenViewController alloc] init];
splashScreen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[navController presentModalViewController:splashScreen animated:NO];

I think I’m just stuck understanding how to tie all the UIViewController subclasses together, and how to reference them from AppDelegate (or whether I should even be doing that), etc. Any tips are appreciated. I can clarify if my question is muddy.

Answer 1

You can move this to MyViewController‘s viewDidLoad

SplashScreenViewController *splashScreen = [[SplashScreenViewController alloc] init];
splashScreen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[navController presentModalViewController:splashScreen animated:NO];

Or you could do this in you AppDelegate, before makeKeyAndVisible

splashView = [[[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, 480)] autorelease];
splashView.image = [UIImage imageNamed:@"Default.png"];
[self.window addSubview:splashView];
[self.window bringSubviewToFront:splashView];

What’s your plan for dismissing the view?
