Splash Screen Problem

I am building an application. For splash screen I've just taken the default.png into resource开发者_Python百科s folder and set the sleep time into AppDelegate.m. Till here it is working fine , My Application is getting launch with the splash screen for given seconds. Now I want to change the ViewTransition of Flipping the splash screen. How can I do that ?

Thanks

Just add a view with uiimageview and set its image to default.png. load this view in the beginning. After you splash screen unloads this shuld be the you view and then flip it.

---

You can't do the flip transition with default.png , try to add a view with that image in window and apply transition to that view.

---

You can't give Transition style to splash screen using deafult.png image.Create another UIViewController with splash image, just dismiss this view controller with required Transition style and time.

---

After the splash screen loads.Just replace it with your new UIImageView and set flip transition.

all the folks above are correct about two things:

i. You can't add transition to the Default.png ii. You need to add UIView (or UIImageView) in order to add transition.

Here's some sample code for you to use:

AppDelegate.h

@interface AppDelegate: .... {
...
@property (strong, nonatomic) UIImageView *splashView;
...
@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:   (NSDictionary *)launchOptions
{
// fade Default.png into next screen
self.splashView = [[UIImageView alloc] initWithFrame:
                   CGRectMake(0, 0, self.window.frame.size.width,        self.window.frame.size.height)];

// get the right image (does not work on simulator)
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) 
    self.splashView.image = [UIImage imageNamed:@"Default.png"];
else {
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    if (UIDeviceOrientationIsLandscape([[UIDevice currentDevice] orientation]))
        self.splashView.image = [UIImage imageNamed:@"Default-Landscape.png"];
    else
        self.splashView.image = [UIImage imageNamed:@"Default-Portrait.png"];
    [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
}
if (self.splashView) {
    [self.window.rootViewController.view addSubview:self.splashView];
    [self.window.rootViewController.view bringSubviewToFront:self.splashView];
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];
    [UIView setAnimationDelegate:self]; 
    [UIView setAnimationDidStopSelector:@selector(startupAnimationDone:finished:context:)];
    self.splashView.alpha = 0.0;
    [UIView commitAnimations];
}
return YES;

}

Notice how I have used setAnimationTransition:UIViewAnimationTransitionNone above. Also, you can use delegate to customize (remove the splashView from super view basically) once done.
