身份验证错误 - 在 iOS 应用程序中集成 SkyDrive

Question

我正在尝试将 SkyDrive 集成到我的 iOS 应用程序中，以下是我编写登录身份验证代码的代码。此处提供的客户端 ID 是为开发人员站点上的应用程序分配的 ID。但是身份验证总是失败。知道错误是什么吗？

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

@implementation PSMainViewController
@synthesize appLogo;
@synthesize userInfoLabel;
@synthesize signInButton;
@synthesize viewPhotosButton;

    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
