I try to create simple transitions between views for my app.
-(void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController{
CATransition *transition;
transition = [CATransition animation];
transition.type = kCAGravityLeft;
transition.duration = 1.25;
[[[viewController view]layer]addAnimation:transition forKey:nil];
}
I put the quartzcore.framework in my project and i call it.
My problem is that the app is launched but without the transition.
Thanks
