hide tab bar in view with push

问题:

I have a tabBar + NavigationViewController. The Tab bar has collection view with cells(Say view1) and with cells a push seague is implemented to another view(Say view2).

In view2 I want to have a navBar but no tab bar.

I tried

self.tabBarController?.tabBar.hidden = true,

it worked fine for view2 but when I went back to view1 by back button the tab was still hidden( even after in view1 class I added self.tabBarController?.tabBar.hidden = false in viewDidLoad func).

How can i make the tab bar reappear in view1?

I'm working in swift.

回答1:

In the viewDidload set the UIViewController hidesBottomBarWhenPushed to yes:

self.hidesBottomBarWhenPushed = YES;

This way the UINavigationController takes care of hiding the tab bar.

回答2:

Use in prepareforsegue

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"showRecipeDetail"]) {
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
    RecipeDetailViewController *destViewController = segue.destinationViewController;
    destViewController.recipeName = [recipes objectAtIndex:indexPath.row];

    // Hide bottom tab bar in the detail view
    destViewController.hidesBottomBarWhenPushed = YES;
}}

Try to check this on your controller!

Bruno Fernandes's answer in Swift:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "YourSegueIdentifier" {
        let destinationController = segue.destinationViewController as! YourViewController
        destinationController.hidesBottomBarWhenPushed = true
    }
}

This was the answer that worked for me. Putting hidesBottomBarWhenPushed in the viewDidLoad method didn't work.

Thanks Bruno!

You have to work with viewWillAppear or viewDidAppear. viewDidLoad will be called when view1 is loading (showing) the first time. If you move from view1 to view2 and back the viewDidLoad won't be called again. Therefore you have to use viewWillAppear or viewDidAppear like

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    self.tabBarController?.tabBar.hidden = false
}

Put this code in your view1 controller. The viewWillAppear or viewDidAppear will be called every time navigating back to view1

if you want to hide TabBarController Bottom Bar : #Swift 3

In YourViewController : in ViewDidLoad() method

self.tabBarController?.tabBar.isHidden = false
