I have used this method in the past to detect if the silent switch is enabled:
- (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;
}
This is no longer working in iOS5 on my iPad or iPhone. Is this a known issue? I haven't been able to find any answers on stack overflow or Apple dev forums.
Hope you can help...
