Has posted on his per­sonal page the inter­view I made to him: http://www2.research.att.com/~bs/interviews.html

The inter­view in in ital­ian lan­guage and is in pdf format.

There is also the orig­i­nal eng­lish ver­sion too.

Enable any class to be an UITableView delegate+datasource” script.

Prob­lem:

your class has to sup­port the  UITable­View del­e­gate and/or data­source and is a sim­ple UITable­View­Con­troller os NSob­ject subclass.

Descrip­tion:

While devel­op­ing on the iPhone, using XCode,  I found really annoy­ing to recre­ate all the uitable­view del­e­gate and data­source meth­ods if the class was before an NSOb­ject or a UIV­iew­Con­troller with­out any table, for now the only way was to do a copy and paste from another class or to cre­ate a new one class that is a sub­class of UITableViewController.

The Solu­tion:

1. XCode: goto Scripts menu->Edit User Scripts
   
2. Cre­ate a new Script
3. Insert the fol­low­ing Code:
   #! /usr/bin/perl –w

   1.  
   2. # Insert UITable­View default meth­ods (del­e­gate and data­source) into a class.
   3. # insertTableViewMethod.pl — inserts del­e­gate and data­source meth­ods into a class.
   4.  
   5. use strict;
   6. print ”
   7. #pragma mark Table view methods

   22. if (cell == nil) {
