Developing an app for an iPhone with audio files that need to be listened too through headphones.
How do I check if headphones aren't plugged in so I can tell the user to plug in headphones.
I have the following code from another thread but the audioSessionGetProperty method is deprecated. Anyone know how to alter the following code to make this work OR have there own code/solution.
Thanks.
- (BOOL)isHeadsetPluggedIn {
UInt32 routeSize = sizeof (CFStringRef);
CFStringRef route;
//Maybe changing it to something like the following would work for iOS7?
//AVAudioSession* session = [AVAudioSession sharedInstance];
//OSStatus error = [session setCategory:kAudioSessionProperty_AudioRoute...?
//the line below is whats giving me the warning
OSStatus error = AudioSessionGetProperty (kAudioSessionProperty_AudioRoute,
&routeSize,
&route);
/* Known values of route:
* "Headset"
* "Headphone"
* "Speaker"
* "SpeakerAndMicrophone"
* "HeadphonesAndMicrophone"
* "HeadsetInOut"
* "ReceiverAndMicrophone"
* "Lineout"
*/
if (!error && (route != NULL)) {
NSString* routeStr = (__bridge NSString*)route;
NSRange headphoneRange = [routeStr rangeOfString : @"Head"];
if (headphoneRange.location != NSNotFound) return YES;
}
return NO;
}
This should work, but I cannot test it right now, I'll do in the evening.
- (BOOL)isHeadsetPluggedIn {
AVAudioSessionRouteDescription* route = [[AVAudioSession sharedInstance] currentRoute];
for (AVAudioSessionPortDescription* desc in [route outputs]) {
if ([[desc portType] isEqualToString:AVAudioSessionPortHeadphones])
return YES;
}
return NO;
}
