AMScrollingNavbar

Scrollable UINavigationBar that follows the scrolling of a UIScrollView or similar view (e.g. UITableView or UIWebView). It works like the navigation bar in Chrome or Facebook's app for iOS7.

I also wrote about this control in this article

Getting Started

Setup

Add pod 'AMScrollingNavbar' to your Podfile
Run pod install
Run open App.xcworkspace
Import UIViewController+ScrollingNavbar.h in your controller
Implement the two following methods:

- (void)viewWillDisappear:(BOOL)animated
{
	[super viewWillDisappear:animated];
	[self showNavBarAnimated:NO];
}

Enable the scrolling

To enable the scrolling effect you simply need to call followScrollView: providing the UIView's instance that will be tracked, like this:

[self followScrollView:self.scrollView];

You can also set a delay (in points) for the gesture that reveals the navigation bar.

[self followScrollView:self.scrollView withDelay:60];

Make sure to have a barTintColor for your UINavigationBar, or you won't see the fade-in and fade-out effects. Also make sure that you are not using a translucent navigation bar. E.g., in your controller:

[self.navigationController.navigationBar setTranslucent:NO];

Set the view constraints

Make sure to set your scrollview's constraint properly. Please note that the library changes the scrollview's superview frame.
