I'm creating a space cocos2d game with objetive-c. I have in the bottom left 2 arrows to move the sprite left or right. I also implemented a swipe gesture to change weapon, however it only happens when I'm not touching the screen.

I would like the player to change weapons while he's moving the sprite and not have to lift the finger from the arrows and stop moving the sprite to change weapons.

Is there any way I can detect Gestures while having a finger pressed un a buton in thes screen?
