申请通知权限注册后（不仅仅是应用程序启动后）

Question

我们可以更改Permission seek方法的默认行为（它在我们启动应用程序时出现）但我想在用户注册时显示它，我在appDelegate中这样做：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let notificationSettings = UIUserNotificationSettings(
        forTypes: [.Badge, .Sound, .Alert], categories: nil)


    application.registerUserNotificationSettings(notificationSettings)

    return true
}

Answer 1

您可以将它放在您想要询问用户的不同类中，如下所示

let notificationSettings = UIUserNotificationSettings(
            forTypes: [.Badge, .Sound, .Alert], categories: nil)

UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
