iOS的推送通知 - 如何在不健全的指定警报和徽章？

问题描述

我想知道如何发送推送通知没有声音。

从苹果的网站：

This says that if I use "default" for the sound file or if I specify a sound file that does not exist, it will play the default alert sound.

But it does specifically state how to have no sound... If I just do not include a sound in the payload (leave it out), will this mean that there will be no sound played?

Thanks

解决方案

That's right. Just don't include sound in the payload. Or, don't even register for sound notification type if you're never going to want to play sounds.
