GTScrollNavigationBar: An Objective-C repository from ronocod

#GTScrollNavigationBar

A scrollable UINavigationBar that follows a UIScrollView. This project was inspired by the navigation bar functionality seen in the Chrome, Facebook and Instagram iOS apps.

=======

##Installation ###CocoaPods Add pod GTScrollNavigationBar to your Podfile. ###Manually Add the GTScrollNavigationBar folder to your project. GTScrollNavigationBar uses ARC, so if you have a project that doesn't use ARC, just add the -fobjc-arc compiler flag to the GTScrollNavigationBar files.

##Usage Set up the navigation controller to use GTScrollNavigationBar:

#import "GTScrollNavigationBar.h"

self.navController = [[UINavigationController alloc] initWithNavigationBarClass:[GTScrollNavigationBar class] 
                                                                   toolbarClass:nil];
[self.navController setViewControllers:@[self.mainViewController] animated:NO];

In your view controller which has a UIScrollView, e.g. UITableViewController, set the UIScrollView object to the GTScrollNavigationBar in viewWillAppear: by:

self.navigationController.scrollNavigationBar.scrollView = self.tableView;

To unfollow the scrollView, simply set scrollView property to nil

self.navigationController.scrollNavigationBar.scrollView = nil;

Implement scrollViewDidScrollToTop: in the view controller to reset the navigation bar's position

- (void)scrollViewDidScrollToTop:(UIScrollView *)scrollView
{
    [self.navigationController.scrollNavigationBar resetToDefaultPosition:YES];
}
