Simple category to show a loading status in a navigation bar in place of left/right items or title.

UINavigationItem-Loading

Easy way to show loading/uploading status for user in a navigation bar.

Introduction

With needing of this pattern again I decide to make this category. So here it is, with just few methods and fully customized in color.

Demo

or build it yourself

pod try UINavigationItem+Loading

Usage

Just import this category in your view controller (which is embed in UINavigationController).

#import <UINavigationItem+Loading.h>

When you need to show loading status just call

[self.navigationItem startAnimatingAt:ANNavBarLoaderPositionCenter];

Left, right and center position are available. So you can also use ANNavBarLoaderPositionLeft or ANNavBarLoaderPositionRight for loader position. When you need to stop it nothing can be more simple as

[self.navigationItem stopAnimating];

That’s all!

To customize color for loader just set it with appearance proxy like this

[UIActivityIndicatorView appearanceWhenContainedIn:[UINavigationBar class], nil].color = [UIColor blackColor];

Installation

Add the following to your CocoaPods Podfile

pod 'UINavigationItem+Loading', '~> 1.1'

or clone it as a git submodule,

or just copy files
