iOS 8-在应用程序未激活时显示来电（不带CallKit）

我使用PushKit/VoIP收到来电请求。问题是我无法启动应用程序来显示来电屏幕，因为在iOS 10之前，CallKit不可用。 我已成功显示通知，但如何从后台启动应用程序

这是我的密码：

 func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, for type: PKPushType) {
    if (pushCredentials.type == .voIP) {
        let pkToken = (pushCredentials.token as NSData).description
        SocketManager.shared.send(pkToken: pkToken)
    }
}


func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) {
    let payloadDict = payload.dictionaryPayload["aps"] as? Dictionary<String, String>
    let message = payloadDict?["alert"]


    Notifications.present(id: "test", title: "test", body: message)
    NSLog("incoming voip notfication 1: \(payload.dictionaryPayload)")
}

func-pushRegistry（registry:PKPushRegistry，didUpdate-pushCredentials:PKPushCredentials，for-type:PKPushType）{
if（pushCredentials.type==.voIP）{
让pkToken=（pushCredentials.token作为NSData）。说明
SocketManager.shared.send（pkToken:pkToken）
}
}
func pushRegistry（registry:PKPushRegistry，didReceiveIncomingPushWith payload:PKPushPayload，for type:PKPushType）{
让payloadDict=payload.dictionaryPayload[“aps”]作为字典
让消息=payloadDict？[“警报”]
通知。当前（id:“测试”，标题：“测试”，正文：消息）
NSLog（“传入voip通知1:\（有效负载.字典payload）”）
}

在iOS 10之前，您需要用户点击通知或您的应用图标来启动您的应用。谢谢@Paulw11My-app在iOS 10中收到voip通知时没有自动启动*
