處理應用程序死亡時的通知操作iOS 10

我在應用程序上處理iOS的本地和遠程通知，並且即時通訊面臨一個問題。當應用程序被終止並且通知到達遠程或本地時，我點擊通知，然後調用didFinishLaunchingWithOptions被調用並打開應用程序。但是，如果我選擇自定義操作而不是點擊通知，我的應用程序會崩潰。處理應用程序死亡時的通知操作iOS 10

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

setActions() 
if #available(iOS 10.0, *) {

請顯示'setActions'。 – shallowThought

我已經通過添加setActions更新了問題 –

我在這裏回答了同樣的問題： http://stackoverflow.com/a/43815251/3934111 –

在調度隊列中使用此代碼。

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil) 
var homeViewController = mainStoryboard.instantiateViewControllerWithIdentifier("HomeViewController") as! HomeViewController 
let nav = UINavigationController(rootViewController: homeViewController) 
appdelegate.window!.rootViewController = nav

當通知到達時，應用程序被殺死只didFinishLaunchingWithOptions被調用，所以如何解決我的問題 –

您的應用程序崩潰是因爲您通常不是從故事板標識符創建viewcontroller對象。您已創建導航控制器對象，那時由於這個原因沒有viewcontrollers設置到導航控制器堆棧中。 – Rajesh
