Question

    - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
 }

I want to call two methods in this above method,

 -(void) movingUp{

  }

  -(void) movingDown {

  }

I want to call moveUp Method when user will move his touch upward direction, and moveDown when user will touch downward direction,
How can I do this,
I used gestures, but it is sensing one touch moving up or down, but I want call these methods again and again, as per user movement of touch, either upside or downwards

Help!

The touchesMoved: is called with a touches set ; you can use it :

CGFloat diff = [[touches anyObject] locationInView:self].y - [[touches anyObject] previousLocationInView:self].y;
if (diff > 0) {
    // moving down
} else {
    // moving up
}
