Php 当应用程序在iOS中处于后台模式时，GCM通知未接收

我已经在我现有的应用程序中配置了GCM，我正在那里收到通知。现在我面临两个问题： 1） 当我退出应用程序或应用程序处于后台时，我没有收到通知。 2） 我没有在iphone的通知区收到通知，只有当我的应用程序运行时，我才直接在那里接收警报消息。当我拉下通知区域时，我在xcode的控制台中收到这样一条消息：“无法连接到GCM：操作无法完成。（com.google.GCM error 2001）。”

下面是我的PHP文件

<?php

// Payload data you want to send to iOSdevice(s)
// (it will be accessible via intent extras)    
$data = array( 'message' => 'Hello World!');

// The recipient registration tokens for this notification
// http://developer.android.com/google/gcm/ 
$ids = array( 'kucy6xoUmx********eeRsla' );

// Send a GCM push
sendGoogleCloudMessage(  $data, $ids );

function sendGoogleCloudMessage( $data, $ids )
{
    // Insert real GCM API key from Google APIs Console
    // https://code.google.com/apis/console/        
    $apiKey = 'AIz******9JA';

    // Define URL to GCM endpoint
    $url = 'https://gcm-http.googleapis.com/gcm/send';

    // Set GCM post variables (device IDs and push payload)     
    $post = array(
                    'registration_ids'  => $ids,
                    'data'              => $data,                   
                    );

    // Set CURL request headers (authentication and type)       
    $headers = array( 
                        'Authorization: key=' . $apiKey,
                        'Content-Type: application/json'
                    );

    // Initialize curl handle       
    $ch = curl_init();

    // Set URL to GCM endpoint      
    curl_setopt( $ch, CURLOPT_URL, $url );

    // Set request method to POST       
    curl_setopt( $ch, CURLOPT_POST, true );

    // Set our custom headers       
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );

    // Get the response back as string instead of printing it       
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

    // Set JSON post data
    curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $post ) );

    // Actually send the push   
    $result = curl_exec( $ch );

    // Error handling
    if ( curl_errno( $ch ) )
    {
        echo 'GCM error: ' . curl_error( $ch );
    }

    // Close curl handle
    curl_close( $ch );

    // Debug GCM response       
    echo $result;

在IOS方面；
服从命令

编辑1:
您可以尝试发送ios通知

我在上面编辑了你的php代码；
变化是

“通知”=>$data

及

$data=array（'message'=>'Hello World！'，'body'=>'Hello World！'）；
GCM在无效状态2下接收通知

在Android和iOS上使用GCM集成的开发人员需要在对GCM服务器的Post调用中添加特定内容。
对于iOS：
我们还需要另外两件事才能让同一个呼叫在iOS中正常工作：
“通知”=>$data，
“内容可用”=>“正确”

Apple push notifications服务要求内容可用性为true。然后“notification”=>$数据帮助通知中心知道通知已到达并需要推送到设备。
可能重复。感谢您的帮助，我添加了“content\u available”=>true、“priority”=>“high”，现在我在xcode控制台中得到一个错误，当应用程序在后台“CM接收无效状态2的通知”时，所以现在我要做的是plz
