如何继续聚光灯搜索和显示内容ViewController

Question

我已经整理了Spotlight搜索,我现在面临的问题是如何根据聚光灯下的项目显示内容视图.

我的应用程序的结构是UITabVC> UINavigationVC> UICollectionVC>UIVC

---

聚光灯和代码如下所示

// Continue Spotlight Search
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
    if userActivity.activityType == CSSearchableItemActionType {
        let uniqueIdentifier = userActivity.userInfo?[CSSearchableItemActivityIdentifier] as! String
        let id = uniqueIdentifier.components(separatedBy: "_")
        let rootTabVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "RootTabVC") as! RootTabVC

        print(id[0], id[1], separator: " - ", terminator: "\n")
        // printed "craft - Shovel"

        switch id[0] {
        case "craft" :
            let craftVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CraftDetailVC") as! CraftItemDetailVC
            let craftRootCollectionVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CraftRootCollectionVC") as! CraftCollectionVC
            let craftItemsCollectionVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CraftItemsCollectionVC") as! CraftItemsCollectionVC
            // MARK: - TODO show vc

        case "character" : break
        case "mob" : break
        case "plant" : break
        case "recipe" : break
        case "thing" : break
        case "material" : break
        default: break
        }
    }

    return true
}

Answer 1

在你的ApplicationDelegate类中实现这个函数:

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {

然后你可以通过以下方式访问点击CSSearchableItem的 uniqueIdentifier:

if let searchActivityIdentifier = userActivity.userInfo [CSSearchableItemActivityIdentifier] as? String { }

然后,您需要做的就是根据searchActivityIdentifier值将用户重定向到相关的视图控制器.(推送,呈现等)
