Easy way to show loading/uploading status for user in a navigation bar.
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.
or build it yourself
pod try UINavigationItem+Loading
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];
Add the following to your CocoaPods Podfile
pod 'UINavigationItem+Loading', '~> 1.1'
or clone it as a git submodule,
or just copy files
