快速简介，我已经开发了适用于iOS和Android的应用程序，他们共享相同的数据库，并且我已经在两个项目中实施了Firebase，根据Google Firebase教程，但是当我的后端发送推送通知时，我成功收到通知在Android上但我的iOS设备或控制台中没有任何内容。
这是我的后端代码（PHP）：
$message = array('message' => 'Blood Donation alert ',
'mobile' => $rdmob,
'name' => $rdname,
'bt' => $rdbt,
'rh' => $rdrh,
'loclat' =>$rdloclat,
'loclon' =>$rdloclon,
'locdetails' =>$BD_R_loc_details);
sendMessageThroughGCM($tokens_arr, $message);
function sendMessageThroughGCM($registatoin_ids, $message)
{
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
);
define("GOOGLE_API_KEY", "AAAA3n_S2aE:APA91bFpFVn5XbhP_FeXXoZGkG9la94WTMsORZwKrzd-0sNKM8nbjM_E2jMcaAjaubMP11pgby4RFUllVAaUBcmkoOaOw7NG-Xa-JOhfY-UCq829Wa49yxw0IttAnSUge_P4Wmtg");
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'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($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
curl_close($ch);
echo json_encode($fields['data']);
}
后端响应：
"multicast_id":8083296270394010691,"success":2,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1487685174974179%af466c60f9fd7ecd"},{"message_id":"0:1487685175118033%85bd0ba8f9fd7ecd"}]}

备注： - 我有APNS证书，我的应用程序成功获得了APNS令牌和FCM令牌。
- 仅当我手动执行此操作时，iOS才会成功收到通知，Firebase控制台 - ＆gt;通知 - ＆gt;发送新通知（定位iOS应用）。
更新：
PHP代码更新
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
'priority' => 'high',
);
我现在已将优先级分配给消息，但仍无法在iOS上接收消息。

我遇到了同样的问题，其背后的原因是iPhone和Android的有效载荷格式不同。 如果有效载荷格式不包含＆＃34;通知＆＃34;密钥，您将不会在iPhone上收到任何通知。
请告诉您的后端PHP开发人员为iOS和Android应用程序创建单独的有效负载格式。
其他明智地创建相同的有效载荷，其中包含＆＃34;通知＆＃34;和＆＃34;数据＆＃34;按键如下。
{ ＆＃34;消息＆＃34;：{ ＆＃34;令牌＆＃34;：＆＃34; bk3RNwTe3H0：CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1 ...＆＃34 ;, ＆＃34;通知＆＃34;：{ ＆＃34;标题＆＃34;：＆＃34;推标题＆＃34;， ＆＃34; body＆＃34;：＆＃34;消息正文＆＃34; }， ＆＃34;数据＆＃34; ：{ ＆＃34;尼克＆＃34; ：＆＃34;尼克＆＃34;， ＆＃34;客房＆＃34; ：＆＃34;房间＆＃34; } } }
