我的应用程序与Firebase服务器连接,也用于发送推送通知.现在,我想更进一步,为通知添加一个动作.在抛出大量教程之后,它仍然不适合我.操作按钮未显示,您可以在此处看到:

这是我的代码:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    UIApplication.shared.applicationIconBadgeNumber = 0
    FirebaseApp.configure()
    registerForPushNotifications()
    return true
}

func registerForPushNotifications() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
        (granted, error) in
        print("Permission granted: \(granted)")

        guard granted else { return }

        let viewAction = UNNotificationAction(identifier: "addToCal",
                                              title: "Zum Kalender hinzufügen",
                                              options: [.foreground])

        let newsCategory = UNNotificationCategory(identifier: "NEW_SESSION",
                                                  actions: [viewAction],
                                                  intentIdentifiers: [],
                                                  options: [])
        UNUserNotificationCenter.current().setNotificationCategories([newsCategory])
        self.getNotificationSettings()
    }
}

func getNotificationSettings() {
    UNUserNotificationCenter.current().getNotificationSettings { (settings) in
        print("Notification settings: \(settings)")
        guard settings.authorizationStatus == …

在 iOS 9 中，开发人员可以使用UIKeyCommand将快捷方式添加到 iPad 应用程序。这些是在外部键盘上输入的，并且函数会做出反应。

有没有办法在mac上的模拟器中测试这些？或者像这样展示它们：

自从在 Xcode 8 (Beta 1) 和 Swift 3 上升级后，我在这一行中出现错误：

account.requestAccessToAccounts(with: accountType, options: nil, completion: {(success: Bool, error: NSError!) -> Void in

它说：

无法将 '(Bool, NSError!) -> Void' 类型的值转换为预期的参数类型 'ACAccountStoreRequestAccessCompletionHandler!'

在该行之前，我定义了“account”和“accountType”：

let account = ACAccountStore()
let accountType = account.accountType(
        withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)

这是我的（使用 Xcode 7 和 Swift 2 工作）代码：

func getTimeline() {

    //https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=twitterapi&count=2
    let account = ACAccountStore()
    let accountType = account.accountType(
        withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)

    account.requestAccessToAccounts(with: accountType, options: nil,
                                            completion: {(success: Bool, error: NSError!) -> Void in

                                                if success {
                                                    let arrayOfAccounts =
                                                        account.accounts(with: …

自从在Xcode 8(Beta 1)和Swift 3上升级后,我在此行中出错:

class CloudViewController: UIViewController, WCSessionDelegate {

它说 :

类型'UIViewController'不符合协议'WCSessionDelegate'

这是我的(使用Xcode 7和Swift 2)代码:

override func viewDidLoad() {
    super.viewDidLoad()

    if(WCSession.isSupported()){
        self.session = WCSession.default()
        self.session.delegate = self
        self.session.activate()
    }
}

func session(_ session: WCSession, didReceiveMessage message: [String : AnyObject]) {

    print("didReceiveMessage")

    watchMessageHandler.getMessage(message)

}

此错误也会显示在WKInterfaceController类中.
