iOS 9 无法使用 URL SCHEME 打开 Instagram 应用 [英] iOS 9 not opening Instagram app with URL SCHEME

问题描述

以下 URL 在 iOS 8.3 及更低版本上打开，但在 iOS 9 上不起作用

The following URL opens on iOS 8.3 and lower, but it does not work and iOS 9

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

为什么网址打不开?

推荐答案

iOS 9 对 URL 方案的处理做了一个小改动.您必须将您的应用使用 Info.plist 中的 LSApplicationQueriesSchemes 键调用的 url 列入白名单.

iOS 9 has made a small change to the handling of URL scheme. You must whitelist the url's that your app will call out to using the LSApplicationQueriesSchemes key in your Info.plist.

主要结论是:

如果您对不在白名单中的 URL 调用canOpenURL"方法，即使安装了已注册处理此方案的应用程序，它也会返回NO".将出现此应用不允许查询方案 xxx"的 syslog 条目.

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.

如果您对不在白名单中的 URL 调用openURL"方法，它将静默失败.将出现此应用不允许查询方案 xxx"的 syslog 条目.

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错误，Apple 将在后续版本中修复此问题.

The author also speculates that this is a bug with the OS and Apple will fix this in a subsequent release.
