iOS Push Notification No Sound
提问by Omer Janjua
This is the code to register for push
这是注册推送的代码
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[application registerForRemoteNotifications];
}
else
{
[application registerForRemoteNotificationTypes: (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
It works fine as the app registers with the server.
当应用程序向服务器注册时，它运行良好。
The PEM files are also done correctly as I can send a push to my device using sandbox APNS.
PEM 文件也正确完成，因为我可以使用沙箱 APNS 向我的设备发送推送。
When I print my JSON payload from didReceiveRemoteNotificationI get this:
当我打印我的 JSON 有效负载时，didReceiveRemoteNotification我得到了这个：
{
aps = {
alert = "Test Push Message";
};
}
The issue is when I receive my push (even when the device is set to loud) it doesn't play a sound.
问题是当我收到推送时（即使设备设置为响亮），它也不会播放声音。
From my knowledge, if you don't specify a sound in the JSON payload it should play the default OS sound.
据我所知，如果您没有在 JSON 负载中指定声音，它应该播放默认的操作系统声音。
In my App notification settings on the phone the sound is enabled by default because when I register I specify UIUserNotificationTypeSound.
在手机上的应用通知设置中，声音默认处于启用状态，因为当我注册时，我指定了UIUserNotificationTypeSound.
Anyone else come across this issue?
还有其他人遇到过这个问题吗？

According to Apple's documentationyou need to specify defaultif you want to the default push notification to be played:
根据Apple 的文档，您需要指定default是否要播放默认推送通知：
The name of a sound file in the app bundle. The sound in this file is played as an alert. If the sound file doesn't exist or default is specified as the value, the default alert sound is played. The audio must be in one of the audio data formats that are compatible with system sounds; see Preparing Custom Alert Sounds for details.
应用程序包中声音文件的名称。此文件中的声音作为警报播放。如果声音文件不存在或默认值指定为默认值，则播放默认警报声音。音频必须是与系统声音兼容的音频数据格式之一；有关详细信息，请参阅准备自定义警报声音。
The final JSON output:
最终的 JSON 输出：
{
"aps" : {
"alert" : "Test Push Message",
"sound" : "default"
};
}

You should modify server JSON output to this. defaultit is sound type of the notification on your phone.
您应该将服务器 JSON 输出修改为此。default它是您手机上通知的声音类型。
{
"aps": {
"alert": "test",
"sound": "default"
}
}
回答by Sushant Jagtap
for playing sound when our app receives push notification your json must contains sound attribute. so json like this
为了在我们的应用程序收到推送通知时播放声音，您的 json 必须包含 sound 属性。所以json是这样的
{
"aps":{
"alert" :"your test message",
"sound":"default"
};
}
