iPhone - How do I know if the vibrate is on or off for iOS?

Question

Do you know how I may know if the iPhone is on vibrate mode ? I don\'t find anything about this on the Web... Too tired to see ?

I want to display an icon in the app

Answer 1

You should be able to achieve this using:

#import "AudioToolbox/AudioToolbox.h"

- (void) ifSilentModeThenShowIcon
{
   CFStringRef state;
   UInt32 propertySize = sizeof(CFStringRef);
   AudioSessionInitialize(NULL, NULL, NULL, NULL);
   AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);

   if(CFStringGetLength(state) == 0)
   { 
     // phone's ringer is off so put
     // some icon showing code here
   }
}
