How to play animation/movie instead of iPhone splash screen?

I want to play an animation(Gif) or a movie instead of Default.png. Is that possible? I tried what is described in this blog :http://www.cuppadev.co.uk/iphone/play开发者_开发技巧ing-animated-gifs-on-the-iphone/ but I don't know how to play a Gif animation instead of Default.png

If you're asking about a sanctioned App Store app, then no, you can't use anything but a static Default.png.

If you're writing an app for jailbroken phone, this may be possible (but I don't know).

The Following code should come in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

NSBundle *bundle = [NSBundle mainBundle];
if(bundle != nil)
{
    NSString *videoPath = [bundle pathForResource:@"trail_video" ofType:@"mp4"];
    if (moviePath)
    {
        videoURL = [NSURL fileURLWithPath:moviePath];
    }
}

theMovie = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];

theMovie.moviePlayer.controlStyle = MPMovieControlStyleNone;
theMovie.moviePlayer.scalingMode = MPMovieScalingModeFill;

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayerDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:theMovie.moviePlayer];

[theMovie.moviePlayer setFullscreen:YES animated:NO];
[theMovie.moviePlayer prepareToPlay];
[theMovie.moviePlayer play];
window.rootViewController = theMovie;
[self.window.rootViewController.view bringSubviewToFront:mMoviePlayer.moviePlayer.view];

In the moviePlayerDidFinish method load the screen which you desire to load.

Unfortunately, it's impossible to do it on the latest iPhone OS. A trick using symbolic link is currently blocked by OS.
