Question

When launching an iOS application, the screen jumps from the Default.png into the interface. For a current project, I’d like to fade in from that Default.png into the app’s interface. Is there a good way to do this?

I took a bit of rooster117 and runmad’s answers, and this is what I came up with.

Add a UIImageView to the first UIViewController’s properties:

@interface DDViewController : UIViewController {
   ...
    UIImageView *coverImageView;
}

...

@property (nonatomic, retain) UIImageView *coverImageView;

Then, for the “home screen” of the iPad app, I call the following:

- (void)viewDidLoad
{
    [super viewDidLoad];

    ...

    coverImageView = [[UIImageView alloc] init];
}

-(void)viewWillAppear:(BOOL)animated {
    UIImage *defaultImage;   
    if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)) {
        NSLog(@"Landscape!");
        defaultImage = [UIImage imageNamed:@"Default-Landscape.png"];
    } else {
        NSLog(@"Portrait!");
        defaultImage = [UIImage imageNamed:@"Default-Portrait.png"];
    }

    coverImageView = [[UIImageView alloc] initWithImage:defaultImage];
    [self.view addSubview:coverImageView];

}

-(void)viewDidAppear:(BOOL)animated {
    //Remove the coverview with an animation
    [UIView animateWithDuration:1.0f animations:^(void) {
        [self.coverImageView setAlpha:0.0];
    } completion:^(BOOL finished){
        [coverImageView removeFromSuperview];
    }];
}
