I encountered the same problem. The solution that worked for me was to set the background of my "MainWindow.xib" to "Clear Color" (default is "White Color"). If you have no xib, you can still set the color in your AppDelegate: [self.window setBackgroundColor:[UIColor clearColor]];

if u need only launcher effect , better try this , light weight library

It seems to me that the method:

- (void)applicationDidFinishLaunching:(UIApplication *)application {

is lacking at the end:

[navigator.window makeKeyAndVisible];

If you need more help, please, post your code...
