您需要创建一个 UIActivityViewController 的实例，这是一个简单的示例

let objectsToShare = ["a string"]
let activityController = UIActivityViewController(
        activityItems: objectsToShare,
        applicationActivities: nil)

    // if your app can run on an iPad, this menu
    // will present as a pop over controller
    // and as such, needs to be configured
    // consider the bar button item property
    // if needed

    // should be the rect that the pop over should anchor to
    activityController.popoverPresentationController?.sourceRect = view.frame
    activityController.popoverPresentationController?.sourceView = view
    activityController.popoverPresentationController?.permittedArrowDirections = .any

    // present the controller
    present(activityController, animated: true, completion: nil)
