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
   8.  
   9. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
   10. return 1;
   11. }
   12.  
   13. // Customize the number of rows in the table view.
   14. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
   15. return 0;
   16. }
   17.  
   18. // Customize the appearance of table view cells.
   19. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
   20. static NSString *CellIdentifier = @\"Cell\";
   21. UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
   22. if (cell == nil) {
   23. cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
   24. }
   25. // Set up the cell…
   26. return cell;
   27. }
   28.  
   29. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
   30. // Navigation logic may go here. Create and push another view controller.
   31. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@\"AnotherView\" bundle:nil];
   32. // [self.navigationController pushViewController:anotherViewController];
   33. // [anotherViewController release];
   34. }
