Mute AVAudioPlayer Background music with UISwitch - ios

Question

I am very new to programming and I am just working on my first app. I haven't been able to find an answer to this for weeks. I would really appreciate some help.
I have background music through AVAudioPlayer (the only sound in my app) that begins playing when my app opens - here is the code in my appdelegate.m:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSString *bgmusic=[[NSBundle mainBundle]pathForResource:#"cloud_two-full-" ofType:#"mp3"];
bgmusic1=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:bgmusic] error:NULL];
bgmusic1.delegate=self;
bgmusic1.numberOfLoops=-1;
[bgmusic1 play];
[bgmusic1 setVolume:1.0];
}
So, I've created a uiswitch that I want to use to be able to mute the background music. Here is the IBAction in my viewcontroller.m:
- (IBAction)speakerOnOff:(id)sender {
static BOOL muted = NO;
if (muted) {
[bgmusic1 setVolume:1.0];
} else {
[bgmusic1 setVolume:0.0];
}
muted = !muted;
}
But when I click the switch to off the music continues to play at its normal volume. I only have 1 view controller. Please help! I just want the music to mute when the switch is clicked to off and then back to volume 1.0 when the switch is back on.

Write this code
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil];
above
bgmusic1=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:bgmusic] error:NULL];
and make your button action like this
- (IBAction)speakerOnOff:(id)sender {
if ( bgmusic1.volume == 0) {
bgmusic1.volume = 1;
} else {
bgmusic1.volume =0;
}
}
