Question

如果我尝试在iOS 11上发送静音推送通知（无徽章/声音/警报）和内容可用，根据静音通知的规格，通知将被忽略，不会转发给应用。

这是通知

{
    "aps" : {
        "content-available" : 1,
    }, 
    "type" : "0"
}

设备日志包含：

<Error>: Ignoring notification with no alert, sound or badge (it.my.app.dev): C146-3838

更完整：

Dec 27 10:11:30 iPierX SpringBoard(UserNotificationsServer)[59] <Notice>: [it.my.app.dev] Received remote notification request C146-3838 [ hasAlertContent: 0, hasSound: 0 hasBadge: 0 hasContentAvailable: 1 hasMutableContent: 0 ]

Answer 1

好的..过了一会儿和一些Apple工程师聊天，在这里，我有它的工作。关键是将通知设置为高优先级作为投放优先级，以及content-available = 1。

当然，静音推送通知通常有速率限制，但总体而言，它可以按预期工作。

Answer 2

这也有效，并且在到达时不会发出声音：

{
    aps = {
        "content-available" : 1,
        sound : ""
    };
}

iOS 11中的静默推送通知被忽略。
