ios - AudioSessionGetProperty deprecated, how to know device is silenced -

-

i'm trying detect user's device silenced or not ( button on side of phone ). found method detect this, audiosessiongetproperty deprecated in ios7.

- (bool)deviceissilenced {         cfstringref state;     uint32 propertysize = sizeof(cfstringref);     osstatus audiostatus = audiosessiongetproperty(kaudiosessionproperty_audioroute, &propertysize, &state);     if (audiostatus == kaudiosessionnoerror) {         nslog(@"audio route: %@", state) // "speaker" regardless of silent switch setting, "headphone" when headphones plugged in         return (cfstringgetlength(state) <= 0);     }     return no; }

anyone got solution this?

according sound switch, there no public api detect state of silent switch, provide hack (using public apis , therefore believed ok ap store approval, still treated caution):
