How do I hide a custom button that I add to a UITabBar?

    availableButton.frame = CGRectMake(0, screenHeight - tabBarHeight!, CGFloat(screenWidth/5.0) * 2.0, tabBarHeight!)
    availableButton.backgroundColor = FlatGreen()
    availableButton.setTitle("Turn On", forState: UIControlState.Normal)
    availableButton.setTitleColor(UIColor.whiteColor(), forState: UIControlState.Normal)
    availableButton.titleLabel?.font = UIFont(name: "Roboto-Bold", size: 20.0)
    self.view.addSubview(availableButton)

This is the button that I added to my TabBarViewController.

When I hide my Tab Bar:

tabBarController?.tabBar.hidden = true

I want this button to be hidden as well.

My button is the width of 2 tab bar items.

enter image description here

You have added this button to your view, perhaps this is very bad approach to work.

self.view.addSubview(availableButton)

as tabbar is behind it so it shows. Either ad this to tabbar by using tabBarItem or hide this button manually

availableButton.hidden = YES;

Your problem will be solved.Thank you

let tabBarContext = UnsafeMutablePointer<()>()

self.tabBar.addObserver(self, forKeyPath: "hidden", options: NSKeyValueObservingOptions.New, context:tabBarContext) 

override func observeValueForKeyPath(keyPath: String, ofObject object: AnyObject, change: [NSObject : AnyObject], context: UnsafeMutablePointer<Void>) {
    if context == tabBarContext && keyPath == "hidden"{
        let newChange = change[NSKeyValueChangeNewKey] as! Int
        self.availableButton.hidden  = (newChange == 1) ? true :false   
    }
}
