Hi Eric,

everything correct so far (datasource, IBAction). You have to write some
methods for the NSTableDataSource protocol.

Here is what worked for me:


//
//  AppController.h
//  ToDoList
//
//  Created by Tom on 04.07.08.
//  Copyright 2008 __MyCompanyName__. All rights reserved.
//

#import <Cocoa/Cocoa.h>


@interface AppController : NSObject {
	IBOutlet NSTextField *textField;
	IBOutlet NSTableView *tableView;
	NSMutableArray *array;
}
- (IBAction) add:(id) sender;
@end

//
//  AppController.m
//  ToDoList
//
//  Created by Tom on 04.07.08.
//  Copyright 2008 __MyCompanyName__. All rights reserved.
//

#import "AppController.h"

@implementation AppController
- (id) init
{
	[super init];
	array = [[NSMutableArray alloc] init];

	return self;
}

- (IBAction) add:(id) sender
{
	NSString *string = [textField stringValue];
	NSLog(@"Got string %@ from textfield", string);

	[array addObject:string];
	[tableView reloadData];
}

- (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView
{
	return [array count];
}

- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn: (NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { return [array objectAtIndex:rowIndex]; }

- (void)tableView:(NSTableView *)aTableView setObjectValue:anObject forTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex { [array replaceObjectAtIndex:rowIndex withObject:anObject]; } @end

Hope this helps,

Tom

First of all, I'm' new to cocoa, so I'm a beginner that just started. I'm trying to make the To-Do list on Chapter 6 from Aaron's new book, Cocoa Programming for Mac OS X Third Edition.

I've made an NSMutableArray, set the data source of the NSTableView to AppController, made an IBACTION and connected it to a Button, made a text field, and connected the AppController and the text field, and made an outlet for the table view, and connected it to the app controller.
For the .m file, I used:
NSString *string = [textField stringValue];
[array insertObject:string atIndex:0];
Then I got stuck....
Help please?
