UISearchBar disable animation

Change the search bar to gray (i.e. background color). This might help you

white is the background color of your nav controller

1) in the storyboard, assign your nav controller class and set its background color to whatever you want ... as in my example I did in viewDidLoad ().

2) set backgroundColor as a table. by default it will be the same as the main background of the navigator controller (do this in storyboard ok)

class NavControllerViewController: UINavigationController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        view.backgroundColor = UIColor.redColor()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */

}

      

        
        
        
      

    

if you want to have the same color as the navigation bar

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    view.backgroundColor = navigationBar.tintColor
}

      

        
        
        
      

    

The statusBar color is caused by the extendedLayoutIncludesOpaqueBars property . It is set to "Yes" by default. Set it to "No", then the status bar will always have the same color.

Hope this helps you.

As per your question, I created a similar demo and concluded that you are getting a space between the nav and search bar because you have set a control bar to search instead of the search bar.

I did some more digging and found out that this is the default search behavior .

Whereas when using the Controller search bar, the appearance of the table also shows a space between the nav bar and the search bar.

Instead of using UISearchBarController, you need to use the UISearch bar in the UIView outside of the UItableView.

You can show and hide the navigation bar in a similar way with the search bar in the following method, using animation to hide and show the navigation bar.

EDIT:

func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {

    UIView.animateWithDuration(0.3, animations: {
        searchBar.showsCancelButton = true
        self.navigationController?.navigationBarHidden = true
        }, completion: { value in
            //comment below lines is you want smooth animation.
            self.navigationController!.navigationBar.alpha = 0
    })
    return true
}

      

        
        
        
      

    

func searchBarCancelButtonClicked(searchBar: UISearchBar) {
    UIView.animateWithDuration(0.3, animations: { () -> Void in
        searchBar.showsCancelButton = false
        searchBar.resignFirstResponder()
           // Uncomment below line for smooth animation effect.
           // self.navigationController!.navigationBarHidden = false
        }, completion: { finished in
            //comment below lines is you want smooth animation.
            self.navigationController!.navigationBar.alpha = 1
            self.navigationController!.navigationBarHidden = false
    })
}

      

        
        
        
      

    

Now you don't need to set the background color as the color of the navbar where the wall doesn't have a smooth animation like it used to when searchBarCancelButtonClicked .

But this won't have the smooth animation like it used to.
This way you can just set the background color as the color of the navigation bar.

Hope this solves your problem.
