ios - UIViewController 到 UITabBarController

Question

我有一个名为 LoginViewController 的 View Controller 其类型为 UIVewController.用户登录后，我想将该 View 传输到由 FirstViewController 组成的 UITabBarController和 SecondViewController.
我尝试使用以下方法来做到这一点:

- (void)switchView {
    FirstViewController *firstView = [[FirstViewController alloc] initWithNibName:nil bundle:nil];
    [self.navigationController pushViewController:firstView animated:YES];
}

但这似乎不起作用。是不是因为我没有考虑整个 UITabBarController？

是的，你应该显示 UITabBarController:

- (void)switchView {
    FirstViewController *firstViewController = [[FirstViewController alloc] initWithNibName:nil bundle:nil];
    SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
    UITabBarController *tabController = [[UITabBarController alloc] init];
    tabController.viewControllers = @[firstViewController, secondViewController];
    [self presentViewController:tabController animated:YES completion:nil];
}
