iOS：在 UIActivityViewController 中禁用 WhatsApp？

Question

我正在使用以下代码使用 UIActivityViewController 仅将字符串共享给 Facebook

UIActivityViewController *activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:activityItems
                                applicationActivities:nil];

activityViewController.excludedActivityTypes = @[UIActivityTypePostToWeibo,
                                   UIActivityTypeMessage,
                                   UIActivityTypeMail,
                                   UIActivityTypePrint,
                                   UIActivityTypeCopyToPasteboard,
                                   UIActivityTypeAssignToContact,
                                   UIActivityTypeSaveToCameraRoll,
                                   UIActivityTypeAddToReadingList,
                                   UIActivityTypePostToFlickr,
                                   UIActivityTypePostToVimeo,
                                   UIActivityTypePostToTencentWeibo,
                                   UIActivityTypeAirDrop,
                                   UIActivityTypePostToTwitter];


[self presentViewController:activityViewController animated:YES completion:^{
...
}

这有效，除了它还会显示 WhatsApp 图标和更多图标。有没有办法去掉这两个？提前致谢！

虽然 rmaddy 的答案曾经是正确的，但对于自 iOS 10 以来遇到此问题的任何人来说，这样做相当简单：

activityController.excludedActivityTypes = [
    UIActivity.ActivityType(rawValue: "net.whatsapp.WhatsApp.ShareExtension")
]

如果你想隐藏其他非系统活动类型，你可以分享给他们，然后使用completionWithItemsHandler闭包中返回的标识符：

shareActivityController.completionWithItemsHandler = { [weak self] (activityType, completed, returnedItems, activityError) in
    print("Activity Type", activityType?.rawValue ?? "?") // <--- Use the identifier this logs!
}

尽管在 OP 问题的情况下，诚然，这仍然不会帮助您将其限制为仅限Facebook，您必须安装所有其他数千个具有共享活动的应用程序才能将它们全部禁用！

以下是我碰巧在 iPhone 上安装的应用程序的所有标识符：

UIActivity.ActivityType(rawValue: "com.apple.reminders.RemindersEditorExtension"),
UIActivity.ActivityType(rawValue: "com.apple.mobilenotes.SharingExtension"),
UIActivity.ActivityType(rawValue: "net.whatsapp.WhatsApp.ShareExtension"),
UIActivity.ActivityType(rawValue: "pinterest.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.facebook.Messenger.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.tinyspeck.chatlyio.share"), // Slack!
UIActivity.ActivityType(rawValue: "ph.telegra.Telegraph.Share"),
UIActivity.ActivityType(rawValue: "com.google.Drive.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.toyopagroup.picaboo.share"), // Snapchat!
UIActivity.ActivityType(rawValue: "wefwef.YammerShare"),
UIActivity.ActivityType(rawValue: "com.fogcreek.trello.trelloshare"),
UIActivity.ActivityType(rawValue: "com.linkedin.LinkedIn.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.hammerandchisel.discord.Share"),
UIActivity.ActivityType(rawValue: "com.google.Gmail.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.google.inbox.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.riffsy.RiffsyKeyboard.RiffsyShareExtension"), //GIF Keyboard by Tenor
UIActivity.ActivityType(rawValue: "com.google.hangouts.ShareExtension"),
UIActivity.ActivityType(rawValue: "com.ifttt.ifttt.share")

不可以，您只能删除 Apple 为其提供常量的活动类型。无法删除出现的第 3 方应用程序或“更多...”活动。

如果您只想与单个特定应用程序共享，则使用UIActivityController.

使用各种 Facebook 库/API 之一与 Facebook 共享您的数据。
