Add NSTableView data to NSPopUpButton items - objective-c

Question

I have a NSTableView where items can be added and deleted. Once items have been added to the table, I would like those items to also show as items for an NSPopUpButton. I tried the addItemsWithTitles: method but it gives me an error.
#import "TableController.h"
#import "Favorites.h"
#interface TableController ()
#property NSMutableArray *array;
#property (weak) IBOutlet NSTableView *tableView;
#property (weak) IBOutlet NSPopUpButton *popButton;
#end
#implementation TableController
- (id)init {
self = [super init];
if (self) {
_array = [[NSMutableArray alloc] init];
}
return self;
}
- (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView {
return [_array count];
}
- (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
Favorites *fav = [_array objectAtIndex:row];
NSString *ident = [tableColumn identifier];
return [fav valueForKey:ident];
}
- (void)tableView:(NSTableView *)tableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
Favorites *fav = [_array objectAtIndex:row];
NSString *ident = [tableColumn identifier];
[fav setValue:object forKey:ident];
}
- (IBAction)add:(id)sender {
[_array addObject:[[Favorites alloc] init]];
[_tableView reloadData];
[_popButton addItemsWithTitles:_array];
}
-(IBAction)delete:(id)sender {
NSInteger row = [_tableView selectedRow];
[_tableView abortEditing];
if (row != -1) {
[_array removeObjectAtIndex:row];
}
[_tableView reloadData];
}
#end
So I tried logging the objectAtIndex:0 for the array and didn't get a string but received some numbers instead:
Array string is <Favorites: 0x10013e820>
And also for reference my Favorites class is
#import "Favorites.h"
#interface Favorites ()
#property (copy) NSString *location;
#end
#implementation Favorites
- (id)init {
self = [super init];
if (self) {
_location = #"City, State or ZIP";
}
return self;
}
#end

Your array has instances of your class, Favorites, and in your addItemsWithTiles: method you are adding those instances, not some string property of those instances, which is what I presume you want. If you use [_array valueForKey:#"whateverKeyHasYourStrings"] as the argument to addItemsWithTitles: instead of just _array, I think it will work ok.
