Disable Multitouch

Greetings

I have a tableview, and a click event for each row, so I click a row and the app opens a new window.

But when I do click with 2 fingers on different rows, the app opens 1 window and inmediately open a 2nd window.

There is a way to disable multitouch, or detect the 1st click, or an event different that 'click' that prevent the multitouch?

Thanks
