创建了新项目并添加了ActionExtension，它工作并显示在Action Activities中，但当我为现有应用程序（包含swift和Objective-c文件的旧应用程序）创建时，Action Extension未显示在设备中。我需要在UiactivityController的Action Extension中显示我的应用程序，但我无法显示For Every Application in Device（设备中的每个应用程序）参考图像

***质询：在模拟器（照片应用程序）中显示，但在模拟器的其他应用程序中未显示，但在设备中运行时，照片应用程序和其他应用程序中均未显示

override func viewDidLoad() {
    super.viewDidLoad()

    // Get the item[s] we're handling from the extension context.

    // For example, look for an image and place it into an image view.
    // Replace this with something appropriate for the type[s] your extension supports.

            if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
                // This is an image. We'll load it, then place it in our image view.
                weak var weakImageView = self.imageView
                itemProvider.loadItemForTypeIdentifier(kUTTypeImage as String, options: nil, completionHandler: { (image, error) in
