IPhone: software checks if vibration is turned on

Can I programmatically check if the iPhone system option is

Settings -> Sounds -> Vibrate on Ring

included?

In my application, I would like to show a warning to the user if this option is disabled.

You can not. Because Apple does not provide an API to access the iPhone settings application.

Perhaps you can try and make sure that you are using the application in iDevice, because the simulator does not have a silent or ringer mode :)

New changes

 -(BOOL)silenced { #if TARGET_IPHONE_SIMULATOR // return NO in simulator. Code causes crashes for some reason. return NO; #endif CFStringRef state; UInt32 propertySize = sizeof(CFStringRef); AudioSessionInitialize(NULL, NULL, NULL, NULL); AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state); if(CFStringGetLength(state) > 0) return NO; else return YES; }

and you can call this method as follows

 if ([self silenced]) { NSLog(@"silenced"); } else { NSLog(@"not silenced"); }

Hope this helps you!
