Is it possible to register a http+domain-based URL Scheme for iPhone apps, like YouTube and Maps?

我的iOS应用程序有一个自定义URL方案，我希望能够通过电子邮件发送一个链接到将要启动应用程序的人，如果它在设备上，或者如果他们没有它就将它们带到应用程序商店。

I have a custom URL scheme for my iOS app, and I want to be able to email a link to someone that will either launch the app if it's on the device, or take them to the app store if they don't have it.

我想要能够发送myapp：// someurl并在appstore上启动或转到myapp，但我认为这不会开箱即用。

I'd like to be able to send myapp://someurl and have that either launch or go to myapp on the appstore, but I don't think this will work out of the box.

相反，我正在考虑创建一个链接，加载一些javascript，它将尝试myapp：// someurl，如果失败将改为加载应用商店链接。

Instead, I'm thinking of creating a link that loads some javascript which will try myapp://someurl, and if that fails will instead load the app store link.

我的javascript知识很糟糕。我可以设置window.location来执行重定向，但似乎没有办法从中捕获错误，以便在失败时执行另一个操作。

My javascript knowledge is crappy. I can set window.location to perform the redirect, but there doesn't seem to be a way to catch errors from that in order to perform another action if that fails.

任何人都知道怎么做？

推荐答案

检查
是否可以注册一个http +域名 - 基于URL方案的iPhone应用程序，如YouTube和地图？

但是你需要自己托管包含脚本的页面，因为javascript里面的电子邮件没有'工作

You do however need to host the page containing the script yourself, since javascript inside email doesn't work
