在 Xcode 中，UIActivityViewController 不显示在社交媒体上分享的任何选项，例如在 Facebook、Twitter 等上分享

Question

我尝试在我的 Xcode 项目 (swift) 中包含 UIActivityViewController，但是当我运行模拟器中的应用程序时，UIActivityViewController 没有'包括任何共享内容的选项（我认为一旦你包括它你可以获得所有选项，例如 "share on Facebook" 和 "share on Twitter"

这是我的代码：

import UIKit
class ViewController: UIViewController {


    @IBAction func shareTextButton(_ sender: UIButton) {


        let text = "This is some text that I want to share."


        let textToShare = [ text ]
        let activityViewController = UIActivityViewController(activityItems: textToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash



        self.present(activityViewController, animated: true, completion: nil)

    }


    @IBAction func shareImageButton(_ sender: UIButton) {


        let image = UIImage(named: "Portrait")


        let imageToShare = [ image! ]
        let activityViewController = UIActivityViewController(activityItems: imageToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash


                self.present(activityViewController, animated: true, completion: nil)
    }

}

这是调试控制台中出现的内容：

有人知道哪里出了问题吗？我该怎么做才能使 Facebook 和 twitter 以及其他社交媒体选项出现在 activity 视图控制器中？谢谢

Answer 1

您的编码正确。

有一个 excludedActivityTypes 属性，您可以在其中编码您想要排除的内容，但如果不排除任何内容，设备上可用的内容都会出现（意思是如果设备上没有 FaceBook 或 Twitter，它就不会）。由于您使用的是模拟器，因此不会出现这些选项。

附带说明一下，调试控制台意味着您可能看到很多 "info" 您可能希望删除。如果是这样，请选择您的构建方案（左上 Xcode），选择 "Edit Scheme"，然后添加以下环境变量：

姓名：OS_ACTIVITY_MODE

值：禁用
