iOS - UINavigationController, Hide navigationBar

Question

I have a minor trouble hiding the navigationBar for my UINavigationController

I have added:

self.navigation!.navigationBar.hidden = true

This, unfortunately leaves some kind of background (white) left behind the white status bar that pushes the content (green) downwards, and an unwanted scroll behaviour where I can drag the content up and down to show/hide the white background. What I need is for the statusbar to take up no vertical space what so ever and lay on top of the content (green)

How do I achieve this? Answers in swift as well obj-c are very welcome

enter image description here EDIT: I have tried various versions of the following, the problem remains -.-

override func loadView() {
    self.view = UIView(frame:UIScreen.mainScreen().bounds)
    self.view.backgroundColor = UIColor.whiteColor()


    self.navigation = UINavigationController(rootViewController: self.guideViewController!)

    self.navigation!.navigationBarHidden = true
    self.navigation!.setNavigationBarHidden(true, animated: true)

    self.view.addSubview(self.navigation!.view)
}

override func viewDidLoad() {
    self.automaticallyAdjustsScrollViewInsets = false
    self.navigation!.automaticallyAdjustsScrollViewInsets = false
}

EDIT 2:

printing:

UIApplication.sharedApplication().statusBarFrame.size.height

after viewDidLoad returns 20

Whats "!" IN > self.navigation!.navigationBar.hidden = true ? — iBhavin

It just means to unwrap an optional value, a variable that isn't set when it's defined is optional and needs to be unwrapped when requested — August Bjornberg

Updated :

Just add this in you ViewDidLoad method

self.automaticallyAdjustsScrollViewInsets = NO;

I falsely believed the issue was occurring in my UINavigationController, after some looking i realised the fault lied in one of my pushed views, adding automaticallyAdjustsScrollViewInsets in the view did the trick! Thanks iBhavin

You can use hide navigation bar like

[self.navigationController setNavigationBarHidden:YES];

Hide status bar

// Hide status bar iOS 7 or later
- (BOOL)prefersStatusBarHidden
{
    return YES;
}

Look at this site: https://developer.xamarin.com/recipes/ios/content_controls/navigation_controller/make_the_nav_bar_disappear/

This site says that "The behavior is slightly different depending on whether the Nav Bar is opaque or translucent"

I hope it is helpful.

I know the question has already been answered but I was having the same issue when hiding a navigation bar then using a UIScrollView in the view.

I fixed it programmatically using:

self.edgesForExtendedLayout = UIRectEdgeNone;

Or in interface builder by deselecting all of these:
