Count Collision Cocos2d 3.0

How can i code collision count? So then it can be displayed as the score :D

This is my collision code

- (BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair monsterCollision:(CCNode *)monster projectileCollision:(CCNode *)projectile {
//Creating another sprite on the position the monster one was.
CCSprite *explosion = [CCSprite spriteWithImageNamed:@"explosion.png"];
explosion.position = monster.position;
[self addChild:explosion];

CCActionDelay *delay = [CCActionDelay actionWithDuration:.0f];
CCActionFadeOut *fade = [CCActionFadeOut actionWithDuration:.4f];
[explosion runAction:[CCActionSequence actionWithArray:@[delay,fade]]];

[monster removeFromParent];
[projectile removeFromParent];
return YES;

}

What would i add to count the collision of the Monster?

Thank you :)

New Code

CCLabelTTF *scorelabel = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"score: %d",score] fontName:@"Verdana-Bold" fontSize:18.0f];
scorelabel.positionType = CCPositionTypeNormalized;
scorelabel.color = [CCColor blackColor];
scorelabel.position = ccp(0.85f, 0.95f); // Top Right of screen
[self addChild:scorelabel];

Declare an attribute on the class to count times of the collision. 

int score;

Then on your init method set it to zero

int score=0;

And finally each time collision happens increment the value by one as.

- (BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair monsterCollision:(CCNode *)monster projectileCollision:(CCNode *)projectile {
//Creating another sprite on the position the monster one was.
CCSprite *explosion = [CCSprite spriteWithImageNamed:@"explosion.png"];
explosion.position = monster.position;
[self addChild:explosion];

CCActionDelay *delay = [CCActionDelay actionWithDuration:.0f];
CCActionFadeOut *fade = [CCActionFadeOut actionWithDuration:.4f];
[explosion runAction:[CCActionSequence actionWithArray:@[delay,fade]]];
score++;

[monster removeFromParent];
[projectile removeFromParent];
return YES;

}
