ios - 请求接收推送操作的权限

Question

我只想在用户按下 ViewController 中的按钮后询问用户的许可。我该怎么做？

应用程序启动后，在我的代码对话框弹出窗口中。除了 AppDelegate 类之外，我无法在任何地方执行 application.registerUserNotificationSettings(我总是出错)。

AppDelegate.swift:

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

    // Notifications
    let notificationType = UIUserNotificationType.Alert
    let settings = UIUserNotificationSettings(forTypes: notificationType, categories: nil)
    application.registerUserNotificationSettings(settings) // <-- that method popups dialog to allow/decline Push

    // Override point for customization after application launch.
    return true
}

您可以在您想要的地方使用它:

UIApplication.sharedApplication().registerUserNotificationSettings(设置)
