SpriteKit Touch on Button Not Working?

I have made a menu screen where the user needs to click the play button in order to proceed to the next scene. However, when I wrote the code and ran it, its not registering my touch on the button image, but its registering the touch when I click above the button on the game name label. enter code here-(id)initWithSize:(CGSize)size {

if (self = [super initWithSize:size]){

    SKSpriteNode *background = [SKSpriteNode spriteNodeWithImageNamed:@"menuscreen"];
    background.position = CGPointMake(284, 160);
    background.size = CGSizeMake(self.frame.size.width, self.frame.size.height);
    [self addChild:background];


    SKLabelNode *gameLabel = [SKLabelNode labelNodeWithFontNamed:@"AmericanTypewriter-Bold"];
    gameLabel.position = CGPointMake(self.frame.size.width/2, self.frame.size.height/1.35);
    gameLabel.text = @"Bouncing Block";
    gameLabel.name = @"gameLabel";
    gameLabel.fontSize = 40;
    [self addChild:gameLabel];

    [self animateWithPulse:gameLabel]; // ** GETS RESET LABEL PULSING ** //

    // ** PULSING TEXT ** //
    SKAction *disappear = [SKAction fadeAlphaTo:0.0 duration:1];
    SKAction *appear = [SKAction fadeAlphaTo:1.0 duration:2];
    SKAction *pulse = [SKAction sequence:@[disappear, appear]];
    [gameLabel runAction:[SKAction repeatActionForever:pulse]];

    SKSpriteNode *menuHero = [SKSpriteNode spriteNodeWithImageNamed:@"blokmanamerica"];
    menuHero.size = CGSizeMake(580, 310);
    menuHero.position = CGPointMake(self.frame.size.width/2, self.frame.size.height/4.4);
    menuHero.name = @"hero";
    [self addChild:menuHero];

   // self.backgroundColor = [SKColor colorWithRed:0.171875 green:0.2421875 blue:0.3125 alpha:1.0];
    SKSpriteNode *startButton = [SKSpriteNode spriteNodeWithImageNamed:@"startButton"];
    startButton.position = CGPointMake(self.frame.size.width/1.85, self.frame.size.height/2); //1.85
    startButton.size = CGSizeMake(300, 220);
    startButton.name = @"startButton";
    [self addChild:startButton];

    SKSpriteNode *startButton2 = [SKSpriteNode spriteNodeWithImageNamed:@"settingsButton"];
    startButton2.position = CGPointMake(self.frame.size.width/1.3, self.frame.size.height/2.5);
    startButton2.size = CGSizeMake(300, 220);
    startButton2.name = @"settingsButton";
    [self addChild:startButton2];

    SKSpriteNode *leaderButton = [SKSpriteNode spriteNodeWithImageNamed:@"leaderboardButton"];
    leaderButton.position = CGPointMake(self.frame.size.width/3.12, self.frame.size.height/2.5);
    leaderButton.size = CGSizeMake(300, 220);
   leaderButton.name = @"leaderboardButton";
    [self addChild:leaderButton];


}
return self;

}

enter code here-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInNode:self];

SKNode *node = [self nodeAtPoint:location];

if ([node.name isEqualToString:@"startButton"]) {

    SKTransition *transition = [SKTransition doorsOpenHorizontalWithDuration:1.0];

    MyScene *game = [[MyScene alloc] initWithSize: CGSizeMake(self.size.width, self.size.height)];

    [self.scene.view presentScene:game transition:transition];
}

}
