iOS: Launch AppStore page within my App

Question

I seen games like Kingdom Clash Castle Story

being able to launch AppStore within their game without minimizing their game. The AppStore page will just slide in from bottom, show a game page, and players can download that game, key in their password, close the page and they are still in the game.

Is there a way to do this? I can only minimize my own app, and open the Appstore.

Please advise. Thanks

You can use SKStoreProductViewController class

Import StoreKit framework

#import <StoreKit/StoreKit.h>

Implement the SKStoreProductViewControllerDelegate

@interface MyViewControllerClass : NSObject <SKStoreProductViewControllerDelegate> {
}

- (void) openAppStore
{
    if( NSStringFromClass([SKStoreProductViewController class]) != nil )
    {
        SKStoreProductViewController *viewCont = [[SKStoreProductViewController alloc] init];
        viewCont.delegate = self;
        [viewCont loadProductWithParameters:[NSDictionary dictionaryWithObject:@"APP_ID_FROM_ITUNES" forKey:SKStoreProductParameterITunesItemIdentifier] completionBlock:nil];
        [self.navigationController presentViewController:viewCont animated:YES completion:nil];
    }
    else
    {
        // open safari
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunes.apple.com/us/app/facebook/id284882215?mt=8"]];
    }
}


// SKStoreProductViewControllerDelegate
-(void)productViewControllerDidFinish:(SKStoreProductViewController *)productViewController
{
    [productViewController dismissViewControllerAnimated:YES completion:nil];
}
