VLCKit: VLCMediaPlayerDelegate in Cocoa app

I am trying to develop a Cocoa app for Mac OSX 10.10 that implements video streaming in VLCKit. Now:

• I put together a .framework library and I imported it into Xcode.
• I added Custom View to my Main.storyboard and set it to VLCVideoView

3. In my ViewController.h, I have implemented VLCMediaPlayerDelegate to receive notifications from the player

Here's my code:

viewController.h

#import <Cocoa/Cocoa.h>
#import <VLCKit/VLCKit.h>

@interface ViewController : NSViewController<VLCMediaPlayerDelegate>

@property (weak) IBOutlet VLCVideoView *_vlcVideoView;

//delegates
- (void)mediaPlayerTimeChanged:(NSNotification *)aNotification;

@end

      

        
        
        
      

    

viewController.m

#import "ViewController.h"

@implementation ViewController
{
    VLCMediaPlayer *player;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    [player setDelegate:self];

    [self._vlcVideoView setAutoresizingMask: NSViewHeightSizable|NSViewWidthSizable];
    self._vlcVideoView.fillScreen = YES;

    player = [[VLCMediaPlayer alloc] initWithVideoView:self._vlcVideoView];

    NSURL *url = [NSURL URLWithString:@"http://MyRemoteUrl.com/video.mp4"];

    VLCMedia *movie = [VLCMedia mediaWithURL:url];
    [player setMedia:movie];
    [player play];
}

- (void)mediaPlayerTimeChanged:(NSNotification *)aNotification
{
    //Here I want to retrieve the current video position.
}

@end

      

        
        
        
      

    

The video starts and plays correctly. However, I can't seem to get the delegate to work. Where am I going wrong?

Here are my questions:

• How do I configure a delegate to receive notifications about the current player time?
• How can I read NSNotification? (I'm not very used to Obj-C)

Thanks in advance for any answer!
