好了，所以我对手机游戏使用AIR和AS3的工作。这里的想法是，我想安装另一款游戏提供激励。

Ok, so I'm working on a mobile game using AIR and AS3. The idea here is that I want to provide an incentive for installing another game.

在换句话说： 用户点击按钮在游戏中A，他们带来的应用程序页面游戏B.用户安装游戏B，可以追溯到游戏，获得的奖励在游戏一个。

In other words: user taps button in game A, brings them to app page for game B. User installs game B, goes back to game A, get's reward in game A.

有没有一种方法来检测游戏B已安装？最有可能的途径就是，如果一个游戏时恢复安装游戏B是刚刚检测到，但我似乎无法找到这样的一种方式，使用AS3 / AIR。

Is there a way to detect that game B has been installed? The most likely way seems to be just detecting if game B is installed when game A resumes, but I can't seem to find a way of doing that using AS3/AIR.

我可能还需要做到这一点为Android和iOS，我以为会需要不同的方法。

I will likely also need to do this for both Android and iOS, which I assume will require different methodology.

有一对夫妇的方式来回答这个问题： 自定义URL方案： https://developer.apple.com/library/ios/documentation/iphone/conceptual/iphoneosprogrammingguide/AdvancedAppTricks/AdvancedAppTricks.html  （与其他应用程序部分的通信）

There are a couple ways to answer this: Custom URL Scheme: https://developer.apple.com/library/ios/documentation/iphone/conceptual/iphoneosprogrammingguide/AdvancedAppTricks/AdvancedAppTricks.html ( the Communicating with Other Apps section)

这需要您正试图向上销售的应用程序，并在事实上实现自定义URL方案，但它是实现一个简单的事情。一旦你的URL方案，您可以进行检查的方法：canOpenURL： 返回一个应用程序是否可以打开指定的URL资源。

This requires that the app you are attempting to up-sell does in fact implement a custom URL scheme, but it is a simple thing to implement. Once you have the URL Scheme, you can make a method that checks: canOpenURL: Returns whether an app can open a given URL resource.
