"Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.
OOP has been around since the 1970's. It's not actually new.
Classes are Awesome

| Why not simply use textField:shouldChangeCharactersInRange:replacementString:? | |
| === | |
| If you google how to limit a length of text field, you'll see many implementations simply using textField:shouldChangeCharactersInRange:replacementString: like | |
| - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string | |
| { | |
| return [[textField.text stringByReplacingCharactersInRange:range withString:string] length] <= MAX_LENGTH; |
| //Create the rect you would like your text to be inside of... | |
| CGRect maxTextRect = CGRectMake(0, 0, 200, 60); | |
| //Create the attributed string | |
| NSAttributedString *theString = //... do all the setup. | |
| //Find the rect that the string will draw into **inside the maxTextRect** | |
| CGRect actualRect = [theString boundingRectWithSize:maxTextRect.size options:NSStringDrawingUsesLineFragmentOrigin context:nil]; | |
| //Offset the actual rect inside the maxTextRect |
| #!/usr/bin/python | |

| # Read a CSV/TSV with a header row (!) and put it into a new sqlite table | |
