iOS Pusher 客户端不会自动重新连接

Question

我正在使用适用于 iOS 的 Pusher 客户端，通过 CocoaPods 安装它(pod 'libPusher', '~> 1.5')。

一切都安排得很好，事件进展顺利。但是，如果设备(运行 iOS 9.0.2 的 iPhone 6s)失去互联网连接(由于我进入飞行模式而导致)，然后在一分钟后重新获得互联网连接(我从飞行模式中退出)，Pusher 就永远不会重新获得连接。

我添加了一些 UIAlertViews 来测试它基于它的委托(delegate)方法正在做什么。

最初显示 connectionWillConnect 和 connectionDidConnect。

打开飞行模式时connectionWillConnect，然后显示connectionWillAutomaticallyReconnection afterDelay of 0.0。

(然后在没有互联网的情况下离开一分钟左右。)

然后什么也没有，即使在重新连接到互联网之后也是如此。并且事件不再被正确接收。

这是我用于所有 Pusher 事物的类(用 Swift 2.0 编写)，它在连接丢失之前工作良好。

class PusherInterface: NSObject, PTPusherDelegate {

    // MARK: - PusherInterface Shared Instance

    /// Singleton instance of the PusherInterface class.
    private static let sharedInstance = PusherInterface()


    // MARK: - Pusher Credentials

    private static let pusherAppId = "MY_APP_ID"
    private static let pusherKey = "MY_KEY"
    private static let pusherSecret = "MY_SECRET"

    /// The connected client used by Pusher to connect to event channels
    private static var client: PTPusher = {
        let pusherClient = PTPusher.pusherWithKey(pusherKey, delegate: PusherInterface.sharedInstance)
        pusherClient.connect()
        return pusherClient as! PTPusher
        }()


    // MARK: - Setup Pusher

    static func startListening() {
        client.subscribeToChannelNamed("MY_CHANNEL")

        client.bindToEventNamed("MY_EVENT") { pusherEvent in
            // Does some stuff with the data back
        }
    }


    // MARK: - Pusher Delegate

    func pusher(pusher: PTPusher!, connectionDidConnect connection: PTPusherConnection!) {
        NSOperationQueue.mainQueue().addOperationWithBlock {
            UIAlertView(title: "connectionDidConnect", message: "", delegate: nil, cancelButtonTitle: "Dismiss").show()
        }
    }

    func pusher(pusher: PTPusher!, connectionWillAutomaticallyReconnect connection: PTPusherConnection!, afterDelay delay: NSTimeInterval) -> Bool {
        NSOperationQueue.mainQueue().addOperationWithBlock {
            UIAlertView(title: "connectionWillAutomaticallyReconnect", message: "afterDelay \(delay)", delegate: nil, cancelButtonTitle: "Dismiss").show()
        }

        return true
    }

    func pusher(pusher: PTPusher!, connectionWillConnect connection: PTPusherConnection!) -> Bool {
        NSOperationQueue.mainQueue().addOperationWithBlock {
            UIAlertView(title: "connectionWillConnect", message: "", delegate: nil, cancelButtonTitle: "Dismiss").show()
        }

        return true
    }

}

关于为什么它不起作用有什么想法吗？

所有想法和理论将不胜感激!谢谢:)

对于我来说，Swift 也不起作用。我安装了swift implementation Pusher 现在工作正常。

    let pusher = Pusher(key: "c984997151153c177dc2")
    pusher.connect()

    let channel = pusher.subscribe("test_channel")
    channel.bind("my_event") { (event: AnyObject?) -> Void in
        print("my_event push received ")
    }
