快速简介，我已经为iOS和Android开发了一个应用程序，它们共享相同的DB，并且我在这两个项目上都实施了Firebase，但是当我的后端发送时，我在Android上成功收到通知的推送通知，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"}]}

注意： - 我有APNS证书，我的应用程序成功地获得了APNS令牌和FCM令牌。
- iOS仅在手动执行此操作时成功地收到通知，firebase Console-> Notification->发送新通知（Targinaling IOS App）。
更新：
PHP代码更新
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
'priority' => 'high',
);
我现在将优先级分配给了消息，但仍无法在iOS上接收。
我遇到了相同的问题，背后的原因是iPhone和Android的有效负载格式不同。如果有效载荷格式不包含"通知"键，则您将不会在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载荷格式。
其他明智的有效负载相同，其中包含"通知"one_answers"数据"键，如下所示。
{ "信息"：{ " token"：" bk3rnwte3h0：ci2k_hhhwgipodkcizvdmexudfq3p1 ..."， "通知"：{ "标题"：" Push Title"， "身体"："消息正文" }，， "数据" ： { "尼克"："尼克"， "房间"："房间" } }}
