iphone sdk. Is it possible to read system settings?

Question

Hi

I need to determine if certain system settings have been set on the iphone. i.e. Whether or not particular sounds are enabled/disabled so I can decide whether or not to play sound in my own app. Is it possible to read the system settings, and if so, how?

Thanks

You can detect if the silent switch is on or not, is this what you are after?

CFStringRef state;
UInt32 propertySize = sizeof(CFStringRef);
AudioSessionInitialize(NULL, NULL, NULL, NULL);
AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);
if(CFStringGetLength(state) > 0)
   NSLog(@"Vibration Off");
else
   NSLog(@"Vibration On");
