ios - 选择某些共享类型后如何获取 UIActivityType

Question

我创建了一个可以共享一些文本的应用程序，但是是否有任何我可以获得的内容，无论是类型还是用户选择目的地的位置？

这里是我使用的一些代码:

let objectsToShare: [String] = [
                        "\(store.name) ",
                        store.url
                    ]
let activityVC: UIActivityViewController = UIActivityViewController(
                        activityItems: objectsToShare,
                        applicationActivities: nil
                    )
self.present(activityVC, animated: true, completion: nil)

Answer 1

在 UIActivityViewController 上设置 completionWithItemsHandler 处理程序，然后检查 activityType...

let objectsToShare = ["\(store.name) ", store.url]
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

activityVC.completionWithItemsHandler = { activityType, completed, _, error in
    guard completed else { return }

    if let error = error {
        // Handle error
        return 
    }

    switch activityType! {  // See UIActivity.ActivityType
    case .saveToCameraRoll:
        //
    case .copyToPasteboard:
        // 
    case etc…
    default:
        // Otherwise check activityType?.rawValue
        // Apple activities begin with "com.apple.UIKit.activity."
        // Others use app specific values
    }
}
present(activityVC, animated: true, completion: nil)
