TabbarControllerHideable 0.3

You want to add pod 'TabbarControllerHideable', '~> 0.3' similar to the following to your Podfile:

target 'MyApp' do
  pod 'TabbarControllerHideable', '~> 0.3'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

TabbarControllerHideable

A drop in UITabbarController with show and hide options

TabbarControllerHideable

Requirements

Xcode 8.0+
iOS 8.3+

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Usage example

To start the TabbarControllerHideable programmatically you can initialize like a normal UITabbarController

        let firstTab: UIViewController = UIViewController()
        let secondTab: UIViewController = UIViewController() 
        let tabs = NSArray(objects: firstTab, secondTab)
        
        let tabBarController = UITabBarHideableController()
        
        // Set ViewControllers
        tabBarController?.setViewControllers(tabs as? [UIViewController], animated: false)

To use the show / hide methods, yours controllers need the UITabbarItemHideable protocol and get the tabbar item programmatically using one of the protocols methods:

    func getTabbarItem(coder:NSCoder) -> UITabBarItem?
    func getTabbarItem(title: String?, image: UIImage?, tag: Int) -> UITabBarItem
    func getTabbarItem(title: String?, image: UIImage?, selectedImage: UIImage?) -> UITabBarItem
    func getTabbarItem(tabBarSystemItem systemItem: UITabBarSystemItem, tag: Int) -> UITabBarItem

import UIKit

class FirstViewController: UIViewController, UITabbarItemHideable {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.tabBarItem = getTabbarItem(tabBarSystemItem: .featured, tag: 1)
        self.view.backgroundColor = UIColor.red
        let button = UIButton(frame: CGRect(x: self.view.center.x - 30, y: self.view.center.y - 30, width: 60, height: 60))
        button.backgroundColor = UIColor.white
        button.addTarget(self, action: #selector(hideTapped), for: .touchUpInside)
        self.view.addSubview(button)
    }
    
    func hideTapped() {
        if !(self.tabBarController as! UITabBarHideableController).isHidded {
            (self.tabBarController as! UITabBarHideableController).hideTabBar(animated: true, duration: 0.75)
        }
        else {
            (self.tabBarController as! UITabBarHideableController).showTabBar(animated: true)
        }
    }
}


class SecondViewController: UIViewController, UITabbarItemHideable {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.tabBarItem = getTabbarItem(tabBarSystemItem: .search, tag: 2)
        self.view.backgroundColor = UIColor.blue
        
        let button = UIButton(frame: CGRect(x: self.view.center.x - 30, y: self.view.center.y - 30, width: 60, height: 60))
        button.backgroundColor = UIColor.white
        button.addTarget(self, action: #selector(hideTapped), for: .touchUpInside)
        self.view.addSubview(button)
    }
    
    func hideTapped() {
        if !(self.tabBarController as! UITabBarHideableController).isHidded {
            (self.tabBarController as! UITabBarHideableController).hideTabBar(animated: true)
        }
        else {
            (self.tabBarController as! UITabBarHideableController).showTabBar(animated: true, duration: 0.75)
        }
    }
}
