相关疑难解决方法(0)

我正在尝试让我的应用程序在Xcode 8.0中运行,并且遇到了错误.我知道这个代码在以前版本的swift中运行良好,但我假设在新版本中更改了代码.这是我正在尝试运行的代码:

let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)     
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.shared().registerForRemoteNotifications()

我得到的错误是"参数标签"(forTypes:,categories :)'与任何可用的重载都不匹配"

是否有一个不同的命令,我可以尝试使其工作？

我使用Swift和Xcode 6构建了一个iPhone应用程序,并使用Parse框架来处理服务.

在关于如何设置推送通知的Parse教程之后,指示建议我将推送通知放在App Delegate文件中.

这是我添加到App Delegate文件的代码...

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    var pushNotificationsController: PushNotificationController?


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

         // Register for Push Notifications
        self.pushNotificationsController = PushNotificationController()

        if application.respondsToSelector("registerUserNotificationSettings:") {
            println("registerUserNotificationSettings.RegisterForRemoteNotificatios")
            let userNotificationTypes: UIUserNotificationType = (.Alert | .Badge | .Sound)
            let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
            application.registerUserNotificationSettings(settings)
            application.registerForRemoteNotifications()
        }

        return true;
    }

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        println("didRegisterForRemoteNotificationsWithDeviceToken")
        let installation = PFInstallation.currentInstallation()
        installation.setDeviceTokenFromData(deviceToken)
        installation.saveInBackground()
    }
}

所以会发生的情况是,第一次启动应用程序时,系统会提示用户授予这些权限.

我想要做的只是在某个动作发生后(即,在应用程序功能的演练期间)提示这些权限,所以我可以提供更多关于为什么我们希望它们允许推送通知的上下文. …
