Question

I know if there is a file named Default.png it shows the image automatically.
but, I want to change the image during it showes.
FYI, I have 2 images Default.png and default2.png.
I want to display default2.png after show Default.png.
I tried followed codes, but it didn’t work.
What do I have to do?

-(BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

//..................................................................
//self.window bullabulla~

[self performSelectorOnMainThread:@selector(showIntro2View) withObject:nil waitUntilDone:YES];
//[self showIntro2View];  //also tried this, but not work.

[self.window addsubview:tabbarController];
[self.window makeKeyAndVisible];
}
-(void) showIntro2View {
UIImageView *intro2 = [[UIImageView alloc]initwithframe:cgrectmake(0,0,320,460)];
intro2.image = [UIImage imagenamed:@"default2.png"];
[self.window addSubview:intro2];
[self.window bringSubviewToFront:intro2];
[NSThread sleepfortimeinterval:2];
}

In your APP DELEGATE.
Something like this should do the job:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    UIImageView *imageView = [[[UIImageView alloc] initWithFrame:self.window.bounds] autorelease];
    UIImage *image = [UIImage imageNamed:@"NAMEOFYOURSPLASHSCREEN.png"];
    imageView.image = image;
    [self.window addSubview:imageView];
    [self.window makeKeyAndVisible];
    [self performSelector:@selector(remove1stSplash:) withObject:imageView afterDelay:5];
    return YES;
}

- (void)remove1stSplash:(UIImageView *)1stView {
    UIImageView *imageView = ...
    [self.window addSubview:imageView];
    [self performSelector:@selector(remove2ndSplash:) withObject:imageView afterDelay:5];
    [1stView removeFromSuperView];
}

- (void)remove2ndSplash:(UIImageView *)2ndView {
    [self.window addSubview:.....
    [2ndView removeFromSuperView];
}
