解析iOS中的應用程序崩潰<8 in swift

Question

我有一個快速的應用程序，我正在橋接Objective C Parse框架。

它不會在模擬器中崩潰，但推送通知在模擬器中不起作用。

下面是代碼：

Parse.setApplicationId("id", clientKey: "id") 
    let notificationTypes:UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound 
    let notificationSettings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil) 
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings) 
    UIApplication.sharedApplication().registerForRemoteNotifications() 
    return true 

它崩潰以下行沒有錯誤消息：

UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings) 

我怎樣才能解決這個問題？

UPDATE

我只是測試它在我的iPad（iOS 8的），現在實在是太崩潰呢？

如果它在iOS <中崩潰8它的原因是-registerUserNotificationsSettings（）僅適用於iOS8。

嘗試類似的東西：

let notificationTypes:UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound 
let notificationSettings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil) 


if(UIApplication.sharedApplication().respondsToSelector(@selector(registerUserNotificationSettings:))){ 
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings) 
    UIApplication.sharedApplication().registerForRemoteNotifications() 
}else{ 
    UIApplication.sharedApplication().registerForRemoteNotificationsTypes(notificationTypes) 
}
