How would I implement a splash screen that animates away? - objective-c

Question

This is what I have so far:
#synthesize window = _window;
#synthesize tabBarController = _tabBarController;
-(void)animate
{
[UIView animateWithDuration:1 animations:^{
splashImage.frame = CGRectMake(0,480,320,480);
}];
[UIView commitAnimations];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
splashImage = [[UIImageView alloc] initWithImage:[UIImage
imageNamed:#"carolinaWolf.png"]];
splashImage.frame = CGRectMake(0, 0, 320, 480);
[self.tabBarController.view addSubview:splashImage];
[self animate];
return YES;
}
My initial view in storyboard is a TabBarController. What I want to happen is: after I finish loading new content into the application, I want to splash screen to animate down and off the screen. This worked before I started using storyboard, why won't it work now?
My AppDelegate.h looks like this:
#import <UIKit/UIKit.h>
#interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>
#property (strong, nonatomic) UIWindow *window;
#property (strong, nonatomic) UITabBarController *tabBarController;
#end
UIImageView *splashImage;

You can directly just add your splashImage to self.window.rootViewController like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIImage *splashImage = [UIImage autoAdjustImageNamed:#"Default.png"];
UIImageView *splashImageView = [[UIImageView alloc] initWithImage:splashImage];
[self.window.rootViewController.view addSubview:splashImageView];
[self.window.rootViewController.view bringSubviewToFront:splashImageView];
[UIView animateWithDuration:1.5f
delay:2.0f
options:UIViewAnimationOptionCurveEaseInOut
animations:^{
splashImageView.alpha = .0f;
CGFloat x = -60.0f;
CGFloat y = -120.0f;
splashImageView.frame = CGRectMake(x,
y,
splashImageView.frame.size.width-2*x,
splashImageView.frame.size.height-2*y);
} completion:^(BOOL finished){
if (finished) {
[splashImageView removeFromSuperview];
}
}];
return YES;
}

This is how I fade away my splash screens:
#pragma mark Fading Default.png Animation
#interface FadeDefault : UIViewController
#end
#implementation FadeDefault
- (void)viewDidLoad
{
[super viewDidLoad];
UIImageView *fader = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Default#2x.png"]];
[fader setFrame:CGRectMake(0,0,320,480)];
/*if ( IDIOM == IPAD ) /* Optional */
{
fader = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Default-Portrait~ipad.png"]];
[fader setFrame:CGRectMake(0,0,768,1024)];
}else
{
fader = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Default#2x.png"]];
[fader setFrame:CGRectMake(0,0,320,480)];
}*/
self.view = fader;
[fader release];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(imageDidFadeOut:finished:context:)];
self.view.alpha = 0.0;
[UIView commitAnimations];
}
- (void)imageDidFadeOut:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context{
[self.view removeFromSuperview];
}
#end
#pragma mark - Application lifecycle
Keep in mind this is an example, although code I actually use and I know works, you need to keep your other didFinishLaunchingWithOptions code in place. Just add the fader code to you existing code.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
/* custom fading Default.png animation */
FadeDefault * fader = [[FadeDefault alloc] init];
[window addSubview:navigationController.view];
[window addSubview:fader.view];
[fader release];
[window makeKeyAndVisible];
return YES;
}
