iOS标签栏不适用于push segue

Question

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    TabBarController *tabBarController = [[TabBarController alloc] init];
    UIViewController *vc2 = [[SearchPageControllerViewController alloc] init];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:vc2];
    NSArray *viewControllers = [NSArray arrayWithObjects:navController, vc2, nil];
    [tabBarController setViewControllers:viewControllers];
}

我使用push segue连接，我有标签栏但是当我用push segue标签栏更改屏幕时获取invis如何解决这个问题我添加了这个代码部分但是现在有用吗？

Answer 1

确保您没有选中Storyboard上视图控制器的Attribute Inspector上的“在推送时隐藏底栏”选项。

Answer 2

为了避免在更改viewController时tabbar消失，我会使用presentViewController，而是使用dismissViewController。

UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"testview"];
[self presentViewController:controller animated:YES completion:NULL];

UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"rootVC"];
[self dismissViewController:controller animated:YES completion:NULL];
