我正致力于通过GCM获取后台通知以使用IOS - 非后台通知已经正常工作。以下是我整合背景通知的步骤:
以下是委托功能的代码:
func application( application: UIApplication,
didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void) {
println("Notification received2: \(userInfo)")
GCMService.sharedInstance().appDidReceiveMessage(userInfo);
NSNotificationCenter.defaultCenter().postNotificationName(messageKey, object: nil,
userInfo: userInfo)
handler(UIBackgroundFetchResult.NoData);
}
这是on-server php脚本的代码:
<?php
$regId = $_GET["regId"];
$message = $_GET["message"];
$data = array( 'price' => $message, 'sound' => 'default', 'body' => 'helloworld', 'title' => 'default', 'badge' => 12, 'content-available' => 1);
$ids = array( $regId);
sendGoogleCloudMessage( $data, $ids );
function sendGoogleCloudMessage( $data, $ids )
{
$apiKey = THE-API-KEY-THAT-I-AM-USING;
$url = 'https://android.googleapis.com/gcm/send';
$post = array(
'registration_ids' => $ids,
'data' => $data,
'content-available' => 1,
);
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $post ) );
$result = curl_exec( $ch );
if ( curl_errno( $ch ) )
{
echo 'GCM error: ' . curl_error( $ch );
}
curl_close( $ch );
echo $result;
}
?>
我尝试通过内部&#34;数据&#34;发送内容可用标志。数组和外部&#34; post&#34;数组,我已将其添加到两者中。
fetchCompletionHandler函数未收到该消息,而是等待应用程序再次处于活动状态并被正常应用程序接收:didRecieveRemoteNotification函数。可能是因为没有通过后台功能收到我的通知?
答案 0 :(得分:2)
您应该向GCM提供 content_available ,而不是内容可用(例如在APN中),您将能够在后台接收推送通知。

P.S。 - 不到五分钟前,我遇到了同样的问题。我们应该更仔细地阅读文档......
