如何确定iPhone是否处于静音模式？ [英] How to find out if the iPhone is on silent mode?

问题描述

我有一个邮寄申请。如果用户成功发送邮件，那么我需要通知邮件已成功发送。为此，我需要知道他的手机是否处于静音模式
（在这种情况下会有'振动'）或常规模式（在这种情况下会有'嘟嘟声'）。任何人都可以帮我吗？

I have a mailing application. If the user sends a mail successfully, then I need to notify that the mail was sent successfully. For that, I need to know if his phone is on silent mode (in which case there will be a 'vibrate') or regular mode (in which case there will be a 'beep'). Can anyone help me with it?

提前致谢

推荐答案

CFStringRef state;
UInt32 propertySize = sizeof(CFStringRef);
AudioSessionInitialize(NULL, NULL, NULL, NULL);
AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);
if(CFStringGetLength(state) == 0)
{
    //SILENT

}
else
{
    //NOT SILENT

}

如果状态字符串为空，那么电话静音 - 否则手机有音频输出

If the state string is empty then the phone is on silent - otherwise the phone has an audio output
