how to call an action every time user taps on Space Key on the keyboard?

[alexandergre]

its like this:
when the user taps on space button on the keyboard I want to call this action:

UItextfield.text=@"";
in other words:
UItextfield.text.clear(); c#

Probably could check inside the textField:shouldChangeCharactersInRange:replacementString:
delegate method.

You are great dude...
but I found another method which is much simpler.

I connected the Event Editing changed to an IBAction.
IBAction:
string input = textfield.text
int a = textfield.text.lenght
if(input[a] isequaltoString @" ")
{The code to call goese here
textfield.text=@"";
} :p
