YISplashScreen 1.1.0

Easy splash screen + animation maker for iOS5+.

YISplashScreen creates another UIWindow on top of status-bar so that transition will be nicer, compared to adding splash image directly on rootViewController.view.
animationBlock is used to hide splash image with two arguments:
- splashLayer: splash image layer (superlayer = another window, by default)
- rootLayer: equivalent to rootViewController.view.layer (superlayer = main window)

Normally, animating splashLayer and rootLayer individually on separate UIWindows is sufficient, but if you want to put them in one main window during animation, prepare it by setting shouldMoveSplashLayerToMainWindowBeforeAnimation = YES so that splashLayer.superlayer will be main window (below status-bar) instead, and more importantly, it prevents from layer-flickering.

Install via CocoaPods

pod 'YISplashScreen'

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];
    
}];
