Can you find out the coordinates of the screen touching at regular intervals?

by NSTimer, etc. Is it possible to know the coordinates of the screen being touched at regular intervals?

It's not when the touch moved.

at the right time. They want to know the coordinates of the finger touching the screen.

Copy the coordinates with touchesBegan to an instance variable, etc., and update or initialize with ...Moved/Ended/Cenceled.I'll send it to the NSTimer for processing.If necessary, copy information other than coordinates.
