问题描述

如何更改播放本地通知的声音？我使用下面的代码播放默认声音：

How do you change the sound that plays for local notifications? I use the code below to play the default sound:

notif.soundName = UILocalNotificationDefaultSoundName;

所以，我在下面尝试了这个，但它没有用。我该怎么办？谢谢你的帮助！

So, I tried this below, and it didn't work. What should I do? Thanks for your help!

notif.soundName = @"sound.caf";

推荐答案

这应该有效。确保声音实际上在您的应用程序包中，格式正确（线性PCM或IMA4 - 几乎任何解释如何转换iOS声音的地方都会告诉您如何操作），并且不到30秒。

That should work. Make sure the sound is actually in your app’s bundle, is in the correct format (linear PCM or IMA4—pretty much anywhere that explains how to convert sounds for iOS will tell you how to do that), and is under 30 seconds.
