I'm new to Objective-c and I'm trying to build some test app.
I have the following method:
-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
//here i should put some code
return TRUE;
}
How can i make some code works inside this method to print which key is pressed in my keyboard?
It's possible to change the state of the key? For example, changing background color or letter color?
Thanks in advance!
