检测从WidgetKit小部件扩展启动的应用程序 [英] Detect app launch from WidgetKit widget extension

问题描述

轻触WidgetKit小部件会自动启动其父应用程序。如何检测我的应用程序是否从其WidgetKit小工具扩展启动？

我找不到有关在应用程序AppDelegate和/或SceneDelegate中捕获此信息的任何文档。

WidgetKit

要检测从WidgetKit小部件扩展启动的应用程序，其中父应用程序支持场景，您需要在父应用程序的SceneDelegate中实现scene(_:openURLContexts:)以从后台状态启动，scene(_:willConnectTo:options:)以冷状态启动。scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)scene(_:willConnectTo:options:)此外，将widgetURL(_:)添加到您的小部件视图中。

Widget的View：

struct WidgetEntryView: View {
    
    var entry: SimpleEntry
    
    private static let deeplinkURL: URL = URL(string: "widget-deeplink://")!

    var body: some View {
        Text(entry.date, style: .time)
            .widgetURL(WidgetEntryView.deeplinkURL)
    }
    
}

父应用程序的SceneDelegate：

// App launched
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    guard let _: UIWindowScene = scene as? UIWindowScene else { return }
    maybeOpenedFromWidget(urlContexts: connectionOptions.urlContexts)
}

// App opened from background
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    maybeOpenedFromWidget(urlContexts: URLContexts)
}

private func maybeOpenedFromWidget(urlContexts: Set<UIOpenURLContext>) {
    guard let _: UIOpenURLContext = urlContexts.first(where: { $0.url.scheme == "widget-deeplink" }) else { return }
    print("🚀 Launched from widget")
}
