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
    
    # Insert UITableView default methods (delegate and datasource) into a class.
    # insertTableViewMethod.pl - inserts delegate and datasource methods into a class.
    
    use strict;
    print "
    #pragma mark Table view methods
    
    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
    }
    
    // Customize the number of rows in the table view.
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 0;
    }
    
    // Customize the appearance of table view cells.
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @\"Cell\";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    // Set up the cell...
    return cell;
    }
    
    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Navigation logic may go here. Create and push another view controller.
    // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@\"AnotherView\" bundle:nil];
    // [self.navigationController pushViewController:anotherViewController];
    // [anotherViewController release];
    }
    
    /*
    // Override to support conditional editing of the table view.
    - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    // Return NO if you do not want the specified item to be editable.
    return YES;
    }
    */
    
    /*
    // Override to support editing the table view.
    - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
    // Delete the row from the data source
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];
    }
    else if (editingStyle == UITableViewCellEditingStyleInsert) {
    // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
    }
    }
    */
    
    /*
    // Override to support rearranging the table view.
    - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath {
    }
    */
    
    /*
    // Override to support conditional rearranging of the table view.
    - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
    // Return NO if you do not want the item to be re-orderable.
    return YES;
    }
    */
    ";
    
    exit 0;
    
  4. Have -quick-fun!

    Thanks for the script.
    However, it is rather difficult to copy-and-paste your script into Xcode.
    (Please try it, and you will understand what I mean.)
