From a quick glance, I'd say you've connected your tableview outlet
to the scrollview in Interface Builder, not the tableview. Tableviews
are contained within scrollviews. You can confirm by checking what
the outlet's connected to under the 'outlets' tab of the info panel in
IB.

I'm doing Challenge from Chapter 6 in the 3rd edition of the Cocoa
Programming for mac OS X book, and I've ran into some trouble.
While I'm trying to reload data, there's always this warning the says:
Warning: 'NSScrollView' may not respond to '-reloadData' (Messages
without a matching method signature will be assumed to return 'id'
and accept '...' as arguments)
I have no idea what it means, and no idea how to correct it.
here's the code:
App Controller.m
-----------------------------------------
#import "AppController.h"
@implementation AppController
- (id) init
{
[super init];
array = [[NSMutableArray alloc] init];
return self;
}
- (NSInteger)numberOfRowsInTableView:aTableView
{
return [array count];
}
- (id)tableView:(NSTableView *)aTableView
objectValueForTableColumn:(NSTableColumn *)aTableColumn
row:(NSInteger)rowIndex
{
return [array objectAtIndex:rowIndex];
}
- (void)tableView:(NSTableView *)anotherTableView
setObjectValue:(id)anObject
forTableColumn:(NSTableColumn *)anotherTableColumn
row:(NSInteger)rowIndex
{
[array replaceObjectAtIndex:rowIndex withObject:anObject];
}
- (IBAction)addThing:(id) sender
{
NSString *string = [textField stringValue];
NSLog(@"Got string %@ from textfield", string);
[array addObject:string];
[tableView reloadData];
}
@end
AppController.h
----------------------------------
#import <Cocoa/Cocoa.h>
@interface AppController : NSObject {
NSMutableArray *array;
IBOutlet NSTextField *textField;
IBOutlet NSScrollView *tableView;
}
- (IBAction)addThing:(id)sender;
@end
-------
I've connected everything. Also, I think there are other problems,
since when I press a button that's supposed to add an object into
the TableView, nothing happens, even though a log appears on the
console.
Thanks!
