Is it possible to detect another finger touch during one finger is touching on the screen? I need to deal with the gesture of the 2nd finger during which I don’t want my first finger to leave the screen. What should be the general logic in the code to handle this?
Thanks.
Yes. Set your view’s
multipleTouchEnabledproperty to yes. Then in your-touchesXXX:…, the first argument (NSSet* touches) will contain 2 elements when 2 fingers are touching the screen.
