ios - How to prefer tap gesture over draw gesture? -

-

in view i'm overriding "touches*" methods let user draw on screen. i'm recording locations. in addition have 2 gesture recognizers on view detect single tap , double tap. if move finger little bit , short enough, recording small "draw" gesture. when raising finger, additional tap gesture triggered. trial , error possibly figure out minimum time , movement threshold i'm sure there smarter ways? need know after how movement and/or save assume no tap gesture trigger.

you can avoid tap gestures. instead of can recognize taps in touch events itself. 

- (void)touchesended:(nsset*)touches withevent:(uievent*)event {     if(touches.count == 1)     {           if([[touches anyobject] tapcount] == 1)        {        // action here single tap        }         else if([[touches anyobject] tapcount] == 2)        {        // action here double tap        }     } }

and have set global bool variable check whether user moved finger on screen. 

bool _ismoved;

and make true in touch move event 

- (void)touchesmoved:(nsset*)touches withevent:(uievent*)event {      _ismoved = yes; }

before recording track, check whether flag true or not? , dont forget make flag false after saving track

hope :)
