我在Xcode 7.1 iOS 9.1中使用swift，我最近注意到当我从parse.com或客户端（在我的应用程序中）发送推送通知时，这里没有噪音是我的AppDelegate：

此处还有一些代码，我试图发送客户端通知：
@IBAction func sendPush(sender: UIBarButtonItem) {
let data = [
"sounds" : "72128__kizilsungur__sweetalertsound4-2.wav"
]
do{
let push = PFPush()
push.setChannel("Members")
push.setData(data)
push.setMessage(notificationTextField.text)
try push.sendPush()
}catch{
print(error)
}
}
如何解决这个问题的任何帮助都会很棒！
答案 0 :(得分：1)
如果正确地将72128__kizilsungur__sweetalertsound4-2.wav作为资产包含在项目中，那么简单的拼写似乎就是问题。将"sounds" : ...更改为"sound" : ...
let data = [
"sounds" : "72128__kizilsungur__sweetalertsound4-2.wav"
]
应该是
let data = [
"sound" : "72128__kizilsungur__sweetalertsound4-2.wav"
]
