Question

我找不到有用的东西或者我可能没有正确理解，所以让我们从头开始。

App A正在向App B发送通知，如下所示：

NSDictionary *data = @{
                           @"alert" : @"Purchase Successful! 1 Remove Ads",
                           @"badge" : @"Increment",
                           @"sounds" : @"Bell.caf",
                           };
    PFPush *push = [[PFPush alloc] init];
    [push setChannels:@[ @"Mets" ]];
    [push setData:data];
    [push sendPushInBackground];

App B接收推送通知，如下所示：

现在，当App B收到推送通知时，为什么我听不到任何声音响起？关闭应用程序并显示横幅通知（我想要声音）时没有声音，应用程序打开时没有声音并且通知出现（只是振动，这很奇怪）。

非常感谢任何帮助。

谢谢

Answer 1

我之前没有做过，但是在解析中搜索我得到了一些解决方案，试试这可能对你有帮助

更改此行

  NSDictionary *data = @{
                       @"alert" : @"Purchase Successful! 1 Remove Ads",
                       @"badge" : @"Increment",
                       @"sounds" : @"Bell.caf",
                       };

到

   NSDictionary *data = @{
                       @"alert" : @"Purchase Successful! 1 Remove Ads",
                       @"badge" : @"Increment",
                       @"sound" : @"Bell.caf",  --> the key Name is not sounds 
                       };

Answer 2

NSDictionary *data = [NSDictionary dictionaryWithObjectsAndKeys:
    @"This is an alert with a custom horn sound!", @"alert",
    @"Increment", @"badge",
    @"homerun.caf", @"sound",
    @"5", @"score_REDSOX",
    @"0", @"score_YANKEES",
    @"4th", @"inning",
    nil];

PFPush *push = [[PFPush alloc] init];
[push setChannels:[NSArray arrayWithObjects:@"REDSOX", @"YANKEES", nil]];
[push setPushToAndroid:false];
[push expireAfterTimeInterval:86400];
[push setData:data];
[push sendPushInBackground];



Push Notifications Web Console
{
  "alert": "This is an alert with a custom horn sound!",
  "badge": "Increment",
  "sound": "homerun.caf",
  "score_REDSOX": "5",
  "score_YANKEES": "0",
  "inning": "4th"
}

Answer 3

我通过PHP代码实现了这一目的，以发送Apple推送通知。

$body['aps'] = array(
'alert' => 'Hi hello message......',
'sound' => 'Bell.caf',
'badge' => '1',
);

可能会对你有帮助。

当我从Parse收到推送通知时如何播放声音？
