ios - UIActivityViewController 仅适用于 Facebook、Twitter 和 Instagram

Question

我正在尝试获取一个 UIActivityViewController 来仅显示 Facebook、Twitter 和 Instagram 的选项。到目前为止我已经做了:

    let shareText = "Hello, world!"

    let image = UIImage(named: "TheImage")
    let activityViewController = UIActivityViewController(activityItems: [shareText,image], applicationActivities: nil)
    activityViewController.excludedActivityTypes = [UIActivityType.addToReadingList,
                                                    UIActivityType.airDrop,
                                                    UIActivityType.assignToContact,
                                                    UIActivityType.copyToPasteboard,
                                                    UIActivityType.mail,
                                                    UIActivityType.message,
                                                    UIActivityType.openInIBooks,
                                                    UIActivityType.print,
                                                    UIActivityType.saveToCameraRoll
                                                    ]
    present(activityViewController, animated: true, completion: {})

但是 UIActivityViewController 仍然给了我不需要的选项。

我也想过使用 NSExtensionItem 获取并接近，但我不确定。

谢谢

有适用于 Facebook 和 Twitter 的选项，您只需添加 exceptedActivityTypes。你错过了。

Instagram 选项在事件类型中仍然不可用

let image = UIImage(named: "TheImage")
let activityViewController = UIActivityViewController(activityItems: [shareText,image], applicationActivities: nil)

activityViewController.excludedActivityTypes = [.addToReadingList,
                                               .airDrop,
                                               .assignToContact,
                                               .copyToPasteboard,
                                               .mail,
                                               .message,
                                               .openInIBooks,
                                               .print,
                                               .saveToCameraRoll,
                                               .postToWeibo,
                                               .copyToPasteboard,
                                               .saveToCameraRoll,
                                               .postToFlickr,
                                               .postToVimeo,
                                               .postToTencentWeibo,
                                               .markupAsPDF
]    

present(activityViewController, animated: true, completion: {})
