在Swift中檢查launchOptions 3

Question

我已將我的代碼轉換爲swift 3，並且已提交到應用商店。當他們打開應用程序時，它會在第一時間崩潰。因此，我檢查了我的crashlog，並在此行崩潰。

if let myLaunchOptions: NSDictionary = launchOptions as NSDictionary? { 

我的整體代碼是這樣的。我知道launchOptions可以是零，它甚至可能不是NSDictionary。這就是爲什麼我這樣檢查，並在這條線上失敗。我可以知道如何檢查/防止迅速3？

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

    if let myLaunchOptions: NSDictionary = launchOptions as NSDictionary? { 
     let test = myLaunchOptions[UIApplicationLaunchOptionsKey.userActivityDictionary] as! NSDictionary 
     let userActivity = test["UIApplicationLaunchOptionsUserActivityKey"] as! NSUserActivity 
     NSLog("test1:" + String(describing: userActivity)) 
     continueUserActivity(userActivity) 
     } 

我的崩潰日誌在這裏。

您應該檢查並獲取用戶的活動是這樣的：

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

    if let userActivityDictionary = launchOptions?[.userActivityDictionary] as? [UIApplicationLaunchOptionsKey : Any], 
     let userActivity = userActivityDictionary[.userActivityType] as? NSUserActivity { 
     continueUserActivity(userActivity) 
    } 

    return true 
}
