[](https://travis-ci.org/Gruber Kristóf/GKFadeNavigationController)

This is an example implementation of a UINavigationController with support of animated hiding and showing it's Navigation Bar.

Features

• Animates tint color
• Takes care of the status bar color
• Similar pattern to -preferredStatusbarStyle
• Uses native controls where possible (e.g. back button)
• Native looking translucent header
• Demo project with elastic header image

Installation

GKFadeNavigationController is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "GKFadeNavigationController"

Usage

1. To run the example project, clone the repo, and run pod install from the Example directory first.
2. Set your Navigation Controller class to GKFadeNavigationController in Storyboard
3. Make your view controllers to conform GKFadeNavigationControllerDelegate protocol
4. Implement -preferredNavigationBarVisibility (return GKFadeNavigationControllerNavigationBarVisibilityHidden or GKFadeNavigationControllerNavigationBarVisibilityVisible)
5. Send a -setNeedsNavigationBarVisibilityUpdateAnimated:animated message to the navigation controller when you want to hide or show the navigation bar

You can see the attached demo project for easier reference.

Requirements

• iOS 7
• iOS 8 SDK

Known limitations

• Does not handle screen rotation fully
• Supports only light navigation bar style out of the box
• Items under the header are not clickable
• Changing the status bar color happens in -viewDidAppear currently
• On iOS 7 it uses semi-transparent view instead of blurred
