iOS 9 不使用 URL SCHEME 打开 Instagram 应用程序

Question

以下网址在 iOS 8.3 及更低版本上打开，但在 iOS 9 上不起作用

let instagramURL = NSURL(string: "instagram://app")

为什么 URL 打不开？

Answer 1

iOS 9 对 URL 方案的处理做了一个小改动。您必须使用 Info.plist 中的 LSApplicationQueriesSchemes 键将您的应用调出的网址列入白名单。

主要结论是:

If you call the “canOpenURL” method on a URL that is not in your whitelist, it will return “NO”, even if there is an app installed that has registered to handle this scheme. A “This app is not allowed to query for scheme xxx” syslog entry will appear.

If you call the “openURL” method on a URL that is not in your whitelist, it will fail silently. A “This app is not allowed to query for scheme xxx” syslog entry will appear.

作者还推测这是操作系统的一个错误，Apple 将在后续版本中修复此问题。
