Question

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?

Thanks in advance

Answer 1

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

}
else
{
    //NOT SILENT

}

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

remember to add the AudioToolbox framework and import. – Thomas Clayson
