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
- 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];
}
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 and enable/disable title view scale feature:
[self followScrollView:self.scrollView withDelay:60 withScaleTitle:YES];
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];
Make sure to set your scrollview's constraint properly. Please note that the library changes the scrollview's superview frame.
