ios - 如何在 AppDelegate 之外调用 “application didRegisterForRemoteNotificationsWithDeviceToken”

Question

我想在 Swift 中使用 POST 请求将我的用户 token ID 保存到我的数据库中。

我用这个功能

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    let types: UIUserNotificationType = [.Alert, .Badge, .Sound]

    let settings: UIUserNotificationSettings = UIUserNotificationSettings( forTypes: types, categories: nil )

    application.registerUserNotificationSettings( settings )
    application.registerForRemoteNotifications()

    return true
}

func application( application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData ) {

    let characterSet: NSCharacterSet = NSCharacterSet( charactersInString: "<>" )

    let deviceTokenString: String = ( deviceToken.description as NSString )
        .stringByTrimmingCharactersInSet( characterSet )
        .stringByReplacingOccurrencesOfString( " ", withString: "" ) as String

    print("token=" + deviceTokenString )

}

问题 = 如何在 AppDelegate 类之外调用 didRegisterForRemoteNotificationsWithDeviceToken？

Answer 1

您可以触发应用程序委托(delegate) didRegisterForRemoteNotificationsWithDeviceToken 委托(delegate)方法，通过调用

UIApplication.sharedApplication().registerForRemoteNotifications()

但是你并没有直接调用这个方法。
