IOS在应用程序未在Swift中运行时接收来自Google GCM的推送通知

我正在使用iOS 9.2和swift 2我使用谷歌GCM从php服务器向iOS用户发送通知当应用程序在前台或后台时，一切都很好，但是当应用程序不再运行时，通知没有出现

这是我的服务器端代码

$access_key =  'access_key';
$registrationIdsIOS = ["registrationIdsIOS"] ; 
// prep the bundle
$msg = array
(
    'message'   => 'message',
    'title'     => 'title',
    'subtitle'  => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1,
    'largeIcon' => 'large_icon',
    'smallIcon' => 'small_icon'
);
$fields = array
(
    'registration_ids'  => $registrationIdsIOS,
    'data'          => $msg,
    'content_available' => true
);
$headers = array
(
    'Authorization: key=' . $access_key,
    'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send');
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result; 

这是我的IOS方面
