YISplashScreen 1.2.1

Easy splash screen + animation maker for iOS5+ (including iOS7).

• YISplashScreen creates another UIWindow on top of status-bar so that transition will be nicer, compared to adding splash image directly on mainWindow.rootViewController.view.
• animationBlock is used to hide splash image with two arguments:
  • splashLayer: splash image layer
  • rootLayer: copy of mainWindow.rootViewController.view.layer

View hierarchy before animation

• mainWindow (not visible)
  • mainWindow.rootViewController.view
• splashWindow
  • splashWindow.rootViewController.view (rotateable)
    • rootLayer (copy of mainWindow.rootViewController.view)
    • splashLayer (splash image layer)

How to use

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // show splash
    [YISplashScreen show];

    // simple fade out
    [YISplashScreen hide];

    return YES;
}

Hiding Animations

// simple fade out
[YISplashScreen hide];

// cube
[YISplashScreen hideWithAnimation:[YISplashScreenAnimation cubeAnimation]];

// manually add animation
[YISplashScreen hideWithAnimationBlock:^(CALayer* splashLayer, CALayer* rootLayer) {

    // splashLayer moves up
    [CATransaction begin];
    [CATransaction setAnimationDuration:0.7];
    [CATransaction setAnimationTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

    splashLayer.position = CGPointMake(splashLayer.position.x, splashLayer.position.y-splashLayer.bounds.size.height);

    [CATransaction commit];

}];

CoreData Migration

By using [YISplashScreen showAndWaitForMigration:completion:] (optional), you can easily integrate simple UIAlertView-confirmation UI.

[YISplashScreen showAndWaitForMigration:^{

    //
    // NOTE: add CoreData migration logic here
    //

    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                             [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
                             [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];

    [persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType
                                             configuration:nil
                                                       URL:url
                                                   options:options
                                                     error:nil];

} completion:^{

    [YISplashScreen hide];

}];
