Authentication error - Integration SkyDrive in iOS application

Question

I am trying to integrate SkyDrive in my iOS application and the following is the code where I have written the login authentication code. The client ID provided here is the one assigned for the application at the developer site. But the authentication always fails. Any idea what is the error ?

static NSString * const CLIENT_ID = @"00000000XXXXXXXXX";

@implementation PSMainViewController
@synthesize appLogo;
@synthesize userInfoLabel;
@synthesize signInButton;
@synthesize viewPhotosButton;
@synthesize userImage;
@synthesize liveClient;
@synthesize currentModal;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        _scopes = [NSArray arrayWithObjects:
                   @"wl.signin",
                   @"wl.basic",
                   @"wl.skydrive",
                   @"wl.offline_access", nil];
        liveClient = [[LiveConnectClient alloc] initWithClientId:CLIENT_ID
                                                          scopes:_scopes
                                                        delegate:self];
    }
    return self;

May be you are not providing the redirect url in case of a desktop application.But if it's the mobile application the you have to check the "Mobile or Desktop client app: " as yes in the api settings
