Hooking mute switch (Jailbroken)

I want to override the mute switch to create a new action whenever the switch is switched. So what is the method that is fired when the switch is changed?

Thanks

Solution

  • Hook this method in the SpringBoard

    SBMediaController - (void)setRingerMuted:(char)

    If you just want to observer the switch event then you can observe system-wide notification com.apple.springboard.ringerstate with darwin notification center like this

    static void RingerStateChanged(CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo)
{
}

CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(),
                                NULL,
                                RingerStateChanged,
                                CFSTR("com.apple.springboard.ringerstate"),
                                NULL,
                                CFNotificationSuspensionBehaviorDeliverImmediately);
