2.4'' TFT LCD Touch screen, can't touch!!

has used tft lcd touch screen on arduino uno rev3?
http://www.ebay.it/itm/121352096483?sspagename=strk:mewnx:it&_trksid=p3984.m1439.l2649 using right shield

i've bought , can make works drawing shapes, text , on code, can't make works on touches events.

i'm trying use code configurate arduino uno rev 3.

just check part of line . https://github.com/adafruit/tftlcd-library/tree/master/examples try library. pin mapping using not correct.

below link can use it has correct pinout configuration
