我有这样的代码
Initialize List View Controller
MTListViewController *listViewController = [[MTListViewController alloc] init];
// Initialize Navigation Controller
UINavigationController *listNavigationController = [[UINavigationController alloc] initWithRootViewController:listViewController];
// Initialize Tab Bar Controller
UITabBarController *tabBarController = [[UITabBarController alloc] init];
// Configure Tab Bar Controller
[tabBarController setViewControllers:@[listNavigationController]];
我在最后一行收到错误“程序中出现意外的'@'”。那怎么了??我的 xcode 版本是 4.2
