Hi guys i am trying to make a window with a view controller (which i guess is like GroupBox in .Net (fix me if i'm wrong..)) and i was trying to start the application on the simulator and it threw an exception. I am using storyboards.
#interface ViewController ()
#end
#implementation ViewController
-(id)init
{
self = [super init];
self.arSongsCollection = [[NSMutableArray alloc] init];
_tableView.delegate = self;
_tableView.dataSource = self.arSongsCollection;
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[_arSongsCollection addObject:[[Song alloc] initWithTitle:#"Song" andArtist:#"Artist" andURL:[NSURL URLWithString:#"http://songurl.com/song.mp3"]]];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end

Answer 1

Read more about tableview datasources, here's the problem:
_tableView.dataSource = self.arSongsCollection;
this ususally should also point to self
_tableView.dataSource = self;
and you have to implement both necessary tableview delegate and dataSource methods in the view controller class.
