Hi,

I have an UITextField object in my view and want to launch a method when user press backspace button and textField is empty.

First I have to do is to create a cursor storing text length, so when cursor changes from 1 to 0 there is nothing to do.

The only way to launch the method is when text length is 0 -> press backspace -> remain to 0.

How to catch the event of pressing the backspace key in my UITextField ?

Thanks in advance !
