iOS:在 UIActivityViewController 中禁用 WhatsApp？

Question

我使用以下代码通过 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:^{
...
}

除了它还显示 WhatsApp 图标和更多图标外，这有效。有没有办法删除这两个？提前致谢!

虽然 rmaddy 的回答曾经是正确的，但对于自 iOS 10 以来遇到此问题的任何人来说，做起来相当简单:

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

如果你想隐藏其他非系统事件类型，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!
}

尽管不可否认，就 OP 的问题而言，这仍然无法帮助您将其限制为仅 Facebook，您必须安装所有其他数千个应用程序共享事件以禁用所有事件!

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")
