通过接口推送消息到IOS，返回消息都是正确的，但是IOS却收不到推送消息

推送接口：
public static PushPayload buildPushObject_ios_tagAnd_alertWithExtrasAndMessage() {
return PushPayload.newBuilder()
.setPlatform(Platform.ios())
.setAudience(Audience.alias("145"))
.setNotification(Notification.newBuilder()
.addPlatformNotification(IosNotification.newBuilder()
.setAlert("mess1")
.setBadge(4)
.setSound("happy")
.addExtra("from", "JPush")
.build())
.build())
.setMessage(Message.content("mess2"))
.setOptions(Options.newBuilder()
.setApnsProduction(true)
.build())
.build();
}

返回消息：

奇怪的是IOS就是收不到消息？
