AudioServicesPlaySystemSound音量控制 [英] AudioServicesPlaySystemSound volume control

问题描述

我想问一下是否有任何方法可以控制系统音效的音量.当我在游戏中按音量控制开关(向上和向下)时，系统声音效果不会受到影响.我还读到，这应该受到铃声音量的影响.但是很奇怪的是，当我向上或向下按下音量时，在扬声器图标的顶部都看不到小铃声.当我按下音量控制按钮时，只会看到顶部没有铃声的扬声器图标.有人知道为什么吗?

I wanted to ask if there is any way to control the volume of the system sound effect. When I press the volume control toggle (up and down) in the game, the system sound effects does not get affected. I also read that this should be affected by the ringer volume. But the weird thing is that when I press the volume up and down, I do not see the little ringer text on top of the speaker icon. I only see the speaker icon without ringer on top when I press the volume control. Does anyone know why?

谢谢.

推荐答案

如果使用audioQueue，iPod或系统声音以外的其他形式在设备上播放音频，则通过侧面按钮调整的音量即为设备音量.如果设备静音，则调整侧面按钮将调整铃声的音量.

If audio is playing on your device using audioQueue, iPod or some other form other than system sounds, the volume adjusted by the side buttons will be the device volume. If the device is otherwise silent, adjusting the side buttons will adjust the ringer volume.
