ios - 带有 dataTaskWithRequest 的 NSURLSession 仅在应用启动时触发,而不是在应用未启动时触发 运行

ios - NSURLSession with dataTaskWithRequest fires only when app launch, not while the app is not running

如题所述,远程通知来了我可以短信回复。如果我点击主页按钮一次,我的 http 请求运行良好,但当应用程序不是 运行 时不起作用,它会等待。当应用程序启动时,它也能正常工作。

// Please work
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {
    print(userInfo["personB"])
    if identifier == "comment-reply" {
        if let response = responseInfo[UIUserNotificationActionResponseTypedTextKey],
            responseText = response as? String {
            let request = NSMutableURLRequest(URL: NSURL(string: "https://example.com/post-ios.php")!)
            request.HTTPMethod = "POST"
            let p = "a=123&b=\(responseText)"
            request.HTTPBody = p.dataUsingEncoding(NSUTF8StringEncoding)
            let task = NSURLSession.sharedSession().dataTaskWithRequest(request)
            task.resume()
        }
    }
    completionHandler()
}

现在,我需要: -VoIP证书, -后台会话配置, -派遣东西, 要么 -上传任务?

谁能帮帮我?

更新 上传任务

func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {
    let id = userInfo["personB"]!
    if identifier == "comment-reply" {
        if let response = responseInfo[UIUserNotificationActionResponseTypedTextKey],
            responseText = response as? String {
            let conf = NSURLSessionConfiguration.backgroundSessionConfigurationWithIdentifier("replyPost")
            let requ = NSMutableURLRequest(URL: NSURL(string: "https://example.com/post-ios.php")!)
                requ.HTTPMethod = "POST"
            let data = "a=123&b=\(responseText)".dataUsingEncoding(NSUTF8StringEncoding)
            let task = NSURLSession(configuration: conf, delegate: self, delegateQueue: NSOperationQueue.mainQueue()).uploadTaskWithRequest(requ, fromData: data!)
            task.resume()
        }
    }
    completionHandler()
}

也不行。我要添加额外的处理程序吗?

当您调用 completionHandler() 时,您的应用程序将再次暂停。这将在您的任务完成之前发生。

你应该调用 uploadTask(with:from:completionHandler:) 而不是 uploadTask(with:from:) 并将 completionHandler() 放入完成处理程序块中。
