It's saying you are trying to send a reloadData message to an instance
of NSScrollView. NSScrollViews do not have a reloadData method. So
the diagnostic approach would be to look for where you have an
NSScrollView and where you are sending a reloadData message to it.
[tableView reloadData];
There's your reloadData message...
@interface AppController : NSObject {
NSMutableArray *array;
IBOutlet NSTextField *textField;
IBOutlet NSScrollView *tableView;
...and sure enough, although you've named it tableView, you've
declared it as an NSScrollView, but more importantly...
I've connected everything.
...you connected your tableView outlet to an instance of
NSScrollView. Change the instance variable declaration from
NSScrollView * to NSTableView *. Go back to IB and make sure you
connect the outlet to an NSTableView. Your code is written to expect
an NSTableView.
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.
This is explained by the errors above.
