Authentication error - Integration SkyDrive in iOS application - ios

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;

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
