Can't get NSTableView to display data.
- by Alberto
Hi! I see there are a lot of questions about this, but nothing helped me to get this work.
I have a nib with a NSTableView with three columns (with the right identifiers set) and a class named ShortcutsTableController. In the nib I have a NSObject with class value ShortcutsTableController. I also connected the NSTableView to my controller as I usually do.
This is header ShortcutsTableController.h.
#import <Cocoa/Cocoa.h>
@interface ShortcutsTableController : NSObject <NSTableViewDataSource> {
IBOutlet NSTableView *shortcutsTable;
NSMutableArray *shortcutsList;
}
- (int) numberOfRowsInTableView: (NSTableView*) tableView;
- (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row;
@property (assign) IBOutlet NSTableView *shortcutsTable;
- (void)setUpTable;
@end
And this is the implementation file ShortcutsTableController.m.
#import "ShortcutsTableController.h"
@implementation ShortcutsTableController
@synthesize shortcutsTable;
- (void)setUpTable {
shortcutsList = [[NSMutableArray alloc] init];
NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys:
@"blabla", @"nameColumn",
@"Bla bla bla", @"shortcutColumn",
@"Ribla", @"actionColumn", nil];
[shortcutsList addObject:dict1];
[shortcutsTable setDataSource:self];
[shortcutsTable reloadData];
}
-(int) numberOfRowsInTableView: (NSTableView *) tableView {
return [shortcutsList count];
}
- (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row {
if (row != -1)
return [[shortcutsList objectAtIndex:row] objectForKey:[tableColumn identifier]];
return nil;
}
@end
But when i try to build nothing appears in the NSTableView. No errors, no warnings. Note that I call setUpTable from within the Delegate Class Method awakeFromNib.
Is there something I am doing wrong? Thank you for you help.

UPDATE. Added lines @property (assign) IBOutlet NSTableView *shortcutsTable; in header and @synthesize shortcutsTable; in implementation. Nothing changes. :(
