As something else to post on this blog, I thought I’d add some code help. Going through a number of questions on StackOverflow that’s reached a number of thousand views, I thought I’d post some of them up on here.

To set a text character limit in an NSTextField, the following code should be placed into your view controller and make sure NSTextField delegate is set to self.

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
//limit the size :
int limit = 20;
return !([textField.text length]>limit && [string length] > range.length);
}
