ios - 快速请求通知权限(iOS 7)

Question

我如何在 iOs 8 和 iOs7 中请求权限。我试过这个:

UIApplication.sharedApplication().registerForRemoteNotificationTypes(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)

但它不起作用。

这是我的代码，仅适用于 iOS 8:

  if(UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:"))) {
            UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert | .Sound, categories: nil))
        }

        else {

        }

最近更改了一些语法。这对我有用。

if(UIApplication.instancesRespondToSelector(#selector(UIApplication.registerUserNotificationSettings(_:)))) {
        UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes:[.Badge , .Sound , .Alert], categories: nil))
        UIApplication.sharedApplication().registerForRemoteNotifications()
}
