xamarin ios 10 在我的应用程序中以编程方式打开应用程序商店应用程序 [英] xamarin ios 10 open app store application programmatically in my app

问题描述

我正在尝试在我的应用中以编程方式打开应用商店应用.

i'm trying to open app store application programmatically in my app.

我想做的是调用一个服务来检查当前的应用程序版本，如果它需要更新，我应该打开应用程序商店应用程序让用户更新我的应用程序.

what i'm trying to do is that i'm calling a service to check at the current app version and if it needs update i should open app store application to let the user update the my app.

注意:应用尚未发布到商店，我仍处于编码阶段.

我尝试在 ViewDidLoad 方法中使用以下代码，但它不起作用(什么也没发生):

i tried to use the following code in ViewDidLoad method, but it's not working (nothing happened):

var nsurl = new NSUrl("itms://itunes.apple.com");
UIApplication.SharedApplication.OpenUrl(nsurl);

推荐答案

通过 itms: 的直接链接仅适用于实际设备，如果您在模拟器上进行测试，请使用 https://itunes.apple.com/us/genre/ios/id36?mt=8 代替.

A direct link via itms: will only work in an actual device, if you are testing on a simulator, use https://itunes.apple.com/us/genre/ios/id36?mt=8 instead.

我建议在实际设备上使用 itms:// 链接，因为它可以防止用户在使用 https:// 链接打开 iTunes 时看到的重定向.

I would recommend using itms:// link on the actual device as it prevents the redirects that user sees when using a https:// link to open iTunes.

bool isSimulator = Runtime.Arch == Arch.SIMULATOR;
NSUrl itunesLink;
if (isSimulator)
{
    itunesLink = new NSUrl("https://itunes.apple.com/us/genre/ios/id36?mt=8");
}
else
{
    itunesLink = new NSUrl("itms://itunes.apple.com");
}
UIApplication.SharedApplication.OpenUrl(itunesLink, new NSDictionary() { }, null);

您可能需要考虑使用 SKStoreProductViewController 将用户留在您的应用程序中，而不是在设备上打开外部应用商店应用程序:

Instead of opening the external Store app on the device, you might want to consider keeping the user inside of your app by using a SKStoreProductViewController:

bool isSimulator = Runtime.Arch == Arch.SIMULATOR;
if (!isSimulator)
{
    var storeViewController = new SKStoreProductViewController();
    storeViewController.Delegate = this;
    var id = SKStoreProductParameterKey.ITunesItemIdentifier;
    var productDictionaryKeys = new NSDictionary("SKStoreProductParameterITunesItemIdentifier", 123456789);
    var parameters = new StoreProductParameters(productDictionaryKeys);
    storeViewController.LoadProduct(parameters, (bool loaded, NSError error) =>
    {
        if ((error == null) && loaded)
        {
            this.PresentViewController(storeViewController, true, () =>
            {
                Console.WriteLine("SKStoreProductViewController Completed");
            });
        }
        if (error != null)
        {
            throw new NSErrorException(error);
        }
    });
}
else
{
    var itunesLink = new NSUrl("https://itunes.apple.com/us/genre/ios/id36?mt=8");
    UIApplication.SharedApplication.OpenUrl(itunesLink, new NSDictionary() { }, null);
}
