ios - VOIP 应用的 StoreKit

Question

由于苹果已经删除了 iOS 应用程序的 VOIP 后台模式。似乎必须使用 PushKit 使应用程序在 VOIP 后台模式下运行。有什么方法可以让 voip 后台模式正常工作而无需在服务器端更改或添加任何脚本？请建议我任何可能的方法。

如果您收到静默推送通知有效负载，那么您必须安排本地通知，因为静默推送通知不会进入通知中心。直到您的本地通知声音文件播放（最多 30 秒），您的应用程序将在后台或终止状态下被调用。你可以在这里做需要活动，但不是 UI 活动。

在点击交互式本地通知时，您可以进行进一步的 UI 活动。

使用以下结构来完成您的任务。

使用这个 simplepush.php 文件

<?php

// Put your device token here (without spaces):

    
      $deviceToken = '1234567890123456789';
//

    
// Put your private key's passphrase here:
$passphrase = 'ProjectName';

// Put your alert message here:
$message = 'My first push notification!';



$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'PemFileName.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client(
//  'ssl://gateway.push.apple.com:2195', $err,
    'ssl://gateway.sandbox.push.apple.com:2195', $err,
    $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp)
    exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body

$body['aps'] = array(
                     'content-available'=> 1,
                     'alert' => $message,
                     'sound' => 'default',
                     'badge' => 0,
                     );

    

// Encode the payload as JSON
    
$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
    echo 'Message not delivered' . PHP_EOL;
else
    echo 'Message successfully delivered' . PHP_EOL;

// Close the connection to the server
fclose($fp);

使用以下命令创建 pem 文件并在上面的代码中使用它

$ openssl x509 -in aps_development.cer -inform der -out PushCert.pem

# Convert .p12 to .pem. Enter your pass pharse which is the same pwd that you have given while creating the .p12 certificate. PEM pass phrase also same as .p12 cert.  
$ openssl pkcs12 -nocerts -out PushKey1.pem -in pushkey.p12

Enter Import Password:

MAC verified OK

Enter PEM pass phrase:

Verifying - Enter PEM pass phrase:

# To remove passpharse for the key to access globally. This only solved my stream_socket_client() & certificate capath warnings.
$ openssl rsa -in PushKey1.pem -out PushKey1_Rmv.pem

Enter pass phrase for PushChatKey1.pem:

writing RSA key

# To join the two .pem file into one file:
$ cat PushCert.pem PushKey1_Rmv.pem > ApnsDev.pem

之后转到 simplepush.php 位置并触发命令 -> php simplepush.php

通过这种方式，您可以测试您的推送工具包通知设置架构。

import UIKit
import PushKit


class AppDelegate: UIResponder, UIApplicationDelegate,PKPushRegistryDelegate{



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


    let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
    application.registerForRemoteNotificationTypes(types)

    self. PushKitRegistration()

    return true
}



//MARK: - PushKitRegistration

func PushKitRegistration()
{

    let mainQueue = dispatch_get_main_queue()
    // Create a push registry object
    if #available(iOS 8.0, *) {

        let voipRegistry: PKPushRegistry = PKPushRegistry(queue: mainQueue)

        // Set the registry's delegate to self

        voipRegistry.delegate = self

        // Set the push type to VoIP

        voipRegistry.desiredPushTypes = [PKPushTypeVoIP]

    } else {
        // Fallback on earlier versions
    }


}


@available(iOS 8.0, *)
func pushRegistry(registry: PKPushRegistry!, didUpdatePushCredentials credentials: PKPushCredentials!, forType type: String!) {
    // Register VoIP push token (a property of PKPushCredentials) with server

    let hexString : String = UnsafeBufferPointer<UInt8>(start: UnsafePointer(credentials.token.bytes),
        count: credentials.token.length).map { String(format: "%02x", $0) }.joinWithSeparator("")

    print(hexString)


}


@available(iOS 8.0, *)
func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {
    // Process the received push
    // From here you have to schedule your local notification

}

}

如果您设置 Socket 架构，则并行。然后 Socket 用于广播数据，例如哪些用户在线/离线，您需要知道而不调用 API 然后您可以使用套接字，服务器上的套接字架构将在线/离线用户的数据发送到设备，而无需从设备发出请求。
