ios - 不显示横幅仅在收到推送通知时振动设备

Question

当我发送推送通知时，我在设备上收到通知，但它没有在 iPhone 的锁定屏幕或通知中心显示为横幅。我的 iPhone 上安装了 iOS 9。

以下是我的代码。

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

    return true
}

func registerForPushNotifications(application: UIApplication)
{

    let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)

    UIApplication.sharedApplication().registerUserNotificationSettings(settings)

    UIApplication.sharedApplication().registerForRemoteNotifications()

}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
{
    print("DEVICE TOKEN = \(deviceToken)")

    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
    var tokenString = ""

    for i in 0..<deviceToken.length
    {
        tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
    }

    print("tokenString: \(tokenString)")
    strDeviceToken = tokenString
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError)
{
    print("Error = \(error)")
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]){
        print(userInfo)
    }

我终于解决了这个问题。他们关于 php 代码的问题不在 iOS 代码中。在 php 代码中，它们缺少 aps 数组中的 alert 关键字，这就是为什么设备仅在收到通知时才振动。
