check whether headphones are plugged in when app starts

Question

I'm sorry about asking this question which is discussed here many times once again. But none of the answers haven't really helped me. All I need is to put some simple code in a viewDidLoad to check whether the headphones are plugged in or are not. (If they aren't I want to pop up simple message, but that's not what I'm asking how to do.) Any help?

This is a great question! Thanks for asking, it's interesting to learn the answer. — hybridcattt, Oct 19 '13 at 21:44

This should achieve what you want (iOS 6+ compatible)

- (BOOL)areHeadphonesPluggedIn {
    NSArray *availableOutputs = [[AVAudioSession sharedInstance] currentRoute].outputs;
    for (AVAudioSessionPortDescription *portDescription in availableOutputs) {
        if ([portDescription.portType isEqualToString:AVAudioSessionPortHeadphones]) {
            return YES;
        }
    }
    return NO;
}

Worked great! thank you. Anyway is there any other solution for older iOS? – TomasJ Oct 19 '13 at 19:51
I haven't tried, but there are several threads about it. This is one example: http://stackoverflow.com/questions/10685313/detecting-if-headset-are-plugged-into-ios-device – Gabriele Petronella Oct 19 '13 at 19:52
thanks, this works in iOS9. There are a number of older strings discussing this topic but they seem out of date. – BenHedges Jul 28 '16 at 20:36

Here is the Swift 1.2 Version of the code written by Gabriele Petronella

//This method checks if headphones are plugged in.

func areHeadphonesPluggedIn()->Bool
{
    var availableOutputs = AVAudioSession.sharedInstance().currentRoute.outputs
    for portDescription in availableOutputs
    {
        if portDescription.portType == AVAudioSessionPortHeadphones
        {
            return true
        }
    }
    return false
}
