How to Hide Tab Bar Controller?

Question

How to Hide Tab Bar Controller ? I want to hide the Tab Bar controller with double tap on UIImageView.

Answer 1

Objective-C

[self.tabBarController.tabBar setHidden:YES];

Swift 3

self.tabBarController?.tabBar.isHidden = true

Swift 2

self.tabBarController?.tabBar.hidden = true

Answer 2

Use Tap Gesture Recognizer to detect double taps on a UIImageView. Then invoke a method on detecting the double double tap. Add the following line of code in that method.

self.tabBarController.tabBar.hidden=YES;

Hope this helps.

Answer 3

Try this code:

[self.tabBarController.tabBar setHidden:YES];

where tabbarcontroller is needed to be defined...

EDIT

AppDelegateFileName *appDelegate = (AppDelegateFileName *) [[UIApplication sharedApplication] delegate];
[appDelegate.tabbarController.tabBar setHidden:YES];

before doing this make sure that you create a @property declaration of tabbarController in appDelegate .h file.

Answer 4

UIViewController has a property

@property(nonatomic, readonly, retain) UITabBarController *tabBarController

which you can set:

self.tabBarController.tabBar.hidden = YES;

Answer 5

Objective-C

[self.tabBarController.tabBar setHidden:YES];

Objective-C 2.0

self.tabBarController.tabBar.hidden = YES;

Swift before iOS 9

tabBarController?.tabBar.hidden = true

Swift iOS 9 and above

tabBarController?.tabBar.isHidden = true

Extra trick with Swift 5 and above: if you would like to change the hidden property then toggle it

if let t = tabBarController?.tabBar {
    t.isHidden = t.!isHidden
}
// is equal to 
tabBarController?.tabBar.isHidden.toggle()

Swift Solution for multiple root view controllers

If you or someone would need to hide the tab bar inside a custom controller, for an app that uses multiple rootViewController try something like this:

//instantiate appDelegate in your controller first
let appDelegate = UIApplication.shared.delegate as! AppDelegate

//then just hide the tab bar as following
appDelegate.window?.rootViewController?.tabBarController?.tabBar.isHidden = true
