Appstore作为iOS6中的模态视图

Question

我注意到当用户点击iOS6邮件应用程序中的应用程序商店链接时,邮件会打开一个代表应用程序商店的模态视图,而不是像之前版本中那样切换到App Store应用程序.

Apple是否提供对此功能的访问权限,或者它是否为其集成程序所独有？

注意:如果你有iOS 6并想要测试它,只需打开appstore和电子邮件应用程序给自己.

我将此方法作为类别添加到UIViewController,但您可以根据自己的需要重新调整它.应用商店ID是应用商店网址中的大号码.确保导入StoreKit框架和头文件!

@import StoreKit;

- (void)presentAppStoreForID:(NSNumber *)appStoreID withDelegate:(id<SKStoreProductViewControllerDelegate>)delegate
{
    if(NSClassFromString(@"SKStoreProductViewController")) { // Checks for iOS 6 feature.

        SKStoreProductViewController *storeController = [[SKStoreProductViewController alloc] init];
        storeController.delegate = delegate; // productViewControllerDidFinish

        // Example App Store ID (e.g. for Words With Friends)
        // @322852954

        [storeController loadProductWithParameters:@{ SKStoreProductParameterITunesItemIdentifier: appStoreID }
                                   completionBlock:^(BOOL result, NSError *error) {
            if (result) {
                [self presentViewController:storeController animated:YES completion:nil];
            } else {
                [[[UIAlertView alloc] initWithTitle:@"Uh oh!" message:@"There was a problem opening the app store" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil] show];
            }
        }];

    } else { // Before iOS 6, we can only open the App Store URL
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/app/id%@",appStoreID]]];
    }
}
