    I'm trying properly handle multi touches. I have enabled multitouches property and I'm using touchesBegan, touchesMoved etc and I've run into the following scenario:

    I get an event for touch A
    Then an event for touch B

    Then, I can track if a touch has been moved, but I dont know whether it was A or B that was moved. Any ideas on how to solve this?

    Thanks

    The UITouch object should be consistent during a touch. So store the pointer to this object, and then compare it with the touch object in touchesMoved().
