UIActivityViewController：排除非Apple共享扩展？ [英] UIActivityViewController: Exclude non-Apple sharing extensions?

问题描述

我想阻止我的应用使用扩展机制将其内容分享给某些其他应用。例如，我希望用户能够共享链接，但不能与Gmail应用分享。

I would like to prevent my app to share its content to certain other apps using the extensions mechanism. For instance, I want the user to be able to share a link, but not with the Gmail app.

我对纪录片的理解是以下内容应该有效： / p>

My understanding of the documentary is that the following should work:

// vieController previously initialised like this: UIActivityViewController(activityItems: [provider], applicationActivities: nil)

viewController.excludedActivityTypes = ["com.google.Gmail.ShareExtension"]

这不起作用。我错过了什么吗？非Apple活动类型是否不适用于此机制？

This doesn't work. Am I missing something? Are non-Apple activity types not working with this mechanism?

推荐答案

显然，自iOS 8.1以来，这是不可能的（无论是错误或预期行为），请参阅： http：/ /johnszumski.com/blog/excluding-third-party-apps-from-ios-8-share-sheet

Apparently, since iOS 8.1 this is not possible anymore (either a bug or intended behaviour), see: http://johnszumski.com/blog/excluding-third-party-apps-from-ios-8-share-sheet
