我在我的应用程序中使用 Kal 库作为日历视图，但它显示为黑色，但是当我在另一个应用程序中添加相同的库时，例如新的 SingleViewApp 它工作正常并显示正常的日历
我的代码是
kal = [[KalViewController alloc] init];
kal.title = @"NativeCal";
kal.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Today" style:UIBarButtonItemStyleBordered target:self action:@selector(showAndSelectToday)] autorelease];
kal.delegate = self;
dataSource = [[EventKitDataSource alloc] init];
kal.dataSource = dataSource;
// Setup the navigation stack and display it.
navController = [[UINavigationController alloc] initWithRootViewController:kal];
UITabBarController *tabBar = [[UITabBarController alloc]init];
tabBar.viewControllers = [NSArray arrayWithObject:navController];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.window.rootViewController = tabBar;
[self.window makeKeyAndVisible];
它给了我这个
