Question

I am currently trying to add a Activity Indicator View to my Splashscreen. It only should appear once – at the first start of the App. Some images are created that are needed for the App, but it takes some time.

While the images are created, the Splashscreen is still visible. So I thought it could maybe be possible to add a Activity Indicator as a Subview of the Splashscreen or at least add it somehow over the Splashscreen.

Is there a possibility to make this possible?

Thanks for your help in advance.

You will need to add the “Splashscreen” as top most view to your window, the “splashcreen” it self is not a view. The system wil just display the default.png:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, -20.0f, 320.0f, 480.0f)];
    splashScreen.backgroundColor = [UIColor blackColor];
    splashScreen.image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Default" ofType:@"png"]];
    [self.window addSubview:splashScreen];

    [self.window makeKeyAndVisible];

    [self performSelector:@selector(applicationDidStart) withObject:nil afterDelay:0.1];

    return YES;
}

splashScreen is a class variable, you could add an Activity Indicator to the splashView.

Then in the applicationDidStart did start methods place the code that will take some time:

- (void) applicationDidStart {
    // some thing that takes a while

   [splashScreen removeFromSuperView];
   [splashScreen release], splashScreen = nil;
}
