我是iOS开发人员的新手，我没有找到任何具体的答案。
假设我有一个包含2个目标的应用程序，FirstApp（firstTarget）和SecondApp（secondTarget）。我在一些帖子中看到你可以从另一个帖子打开一个应用程序，我确实这样做：
if UIApplication.shared.canOpenURL(aUrl as! URL) {
if #available(iOS 10.0, *) {
UIApplication.shared.open(aUrl!)
} else {
// Fallback on earlier versions
}
但是我可以将它打开到SecondApp中的特定VC吗？
我在我的项目中包含了UniversalLink，还有AppDelegate方法，其中包含警报：
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
print("UNIVERSAL LINK")
let alert = UIAlertController(title: "Test", message:"Message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
self.window?.rootViewController?.present(alert, animated: true, completion: nil)
return true
}
问题是，只有在我再重复一次动作之后它才会起作用。这是第一次只打开应用程序。如果我返回FirstApp并重复操作，则弹出警报。
我可以用其他方式来做，或者你有这样的解决方案吗？
通知是否以相同的方式工作？当我点击它时，它会将您重定向到特定的VC。
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let noNetworkView = UIView()
var reachability:Reachability!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
return SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
let alert = UIAlertController(title: "Test", message:"Message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
self.window?.rootViewController?.present(alert, animated: true, completion: nil)
return true
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
return SDKApplicationDelegate.shared.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}
func application(_ application: UIApplication, handleOpen url: URL) -> Bool {
return true
}
func applicationWillTerminate(_ application: UIApplication) {
self.reachability.stopNotifier()
self.saveContext()
}
