Unrecognized Selector when I click on CCMenuItemImage

Unrecognized Selector when I click on CCMenuItemImage

I'm trying to load a start menu for a game, and I've added a play button
using a CCMenuItemImage. Everything loads just fine. However, when I try
to click on the play button, I get this error message.
013-08-18 13:38:46.091 PeevedPenguins-iOS[5169:c07] * Terminating app due
to uncaught exception 'NSInvalidArgumentException', reason:
'-[StartMenuLayer ]: unrecognized selector sent to instance 0x9e5b400'
I don't know what I'm doing wrong since my selector is defined and all.
Please help me out? I've been pulling my hair out trying to figure out why
Xcode would do this
@interface StartMenuLayer ()
@end
@implementation StartMenuLayer
-(id) init
{
if ((self = [super init]))
{
CCMenu *myMenu = [CCMenu menuWithItems: nil];
CCMenuItemImage *menuBackground = [CCMenuItemImage
itemWithNormalImage:@"menu-background-hd.png"
selectedImage:@"menu-background-hd.png" target:self selector:nil];
[myMenu addChild:menuBackground];
CCMenuItemImage *menuPlayButton = [CCMenuItemImage
itemWithNormalImage:@"button-hd.png"
selectedImage:@"button-hd.png" target:self
selector:@selector(playGame:)];
menuPlayButton.position = ccp(0, 0);
[myMenu addChild:menuPlayButton];
CCMenuItemImage * menuItem3 = [CCMenuItemImage
itemWithNormalImage:@"catapult-hd.png"
selectedImage:
@"catapult-hd.png"
target:self
selector:@selector(doSomethingThree:)];
[myMenu addChild: menuItem3];
menuPlayButton.position = ccp(0,-83.5);
[self addChild:myMenu];
}
return self;
}
-(void) playGame:(CCMenuItem *)sender
{
// [[CCDirector sharedDirector] replaceScene: (CCScene*)[[GameLayer
alloc] init]];
NSLog(@"Play the game!");
}
- (void) doSomethingThree:(CCMenuItem *)sender
{
NSLog(@"The third menu was called");
}
@end
