Question

按照推送通知的Parse.com教程，我把这个Swift代码放到我的应用程序didFinishLaunchingWithOptions方法中：

        // Register for Push Notitications
    if application.applicationState != UIApplicationState.Background {
        // Track an app open here if we launch with a push, unless
        // "content_available" was used to trigger a background push (introduced in iOS 7).
        // In that case, we skip tracking here to avoid double counting the app-open.

        let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
        let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
        var pushPayload = false
        if let options = launchOptions {
            pushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil
        }
        if (preBackgroundPush || oldPushHandlerOnly || pushPayload) {
            PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
        }
    }
    if application.respondsToSelector("registerUserNotificationSettings:") {
        let userNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
        let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    } else {
        let types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Alert | UIRemoteNotificationType.Sound
        application.registerForRemoteNotificationTypes(types)
    }

我收到了这两个警告：

iOS版本8.0中不推荐使用
'UIRemoteNotificationType'：使用UIUserNotificationType进行用户通知，使用registerForRemoteNotifications接收远程通知。
iOS版本8.0中不推荐使用'registerForRemoteNotificationsTypes'：请使用registerForRemoteNotifications和registerUserNotificationSettings：而不是

我可以简单地换掉它告诉我的内容吗？

答案非常黑白分明。是的，您可以简单地将其换掉，但需要注意一点：

如果你的目标设备是iOS 7，那么你就不需要了。但是，如果您正在为iOS7开发...我的意见，请停止它。截至8月31日和According to Apple，并没有那么多用户在他们的设备上仍然拥有此操作系统，并且该数据甚至不包括公共iOS 9，因此您在操作系统上浪费了大量时间没人用。但是，如果确实必须支持iOS 7，除了不推荐使用的版本之外，还需要包含所有这些内容。否则，你可以像你所说的那样用非弃用的版本交换它。

这是一个Swift 2.0示例：

if #available(iOS 8.0, *) {
   let types: UIUserNotificationType = [.Alert, .Badge, .Sound]
   let settings = UIUserNotificationSettings(forTypes: types, categories: nil)
   application.registerUserNotificationSettings(settings)
   application.registerForRemoteNotifications()
} else {
   let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
   application.registerForRemoteNotificationTypes(types)
}

Parse.com UIRemoteNotificationType已过时
