JDFNavigationBarActivityIndicator is a UIView subclass that provides an easy, space-effective way to show an activity indicator on a UINavigationBar.
It is visually similar in concept to the progress indicator shown in iOS Safari, in that it appears as a thin, animating line at the bottom of a navigation bar. The difference is that it is an indeterminate progress indicator, making it useful for when you don't know the completion progress of a task.
Create an instance with the vanilla init initialiser. You do not need to set its frame. Use addToNavigationBar:startAnimating: to add it to your desired UINavigationBar. Methods are provided for starting & stopping the animation. You should call setNeedsLayout after device rotation, if required.
You can supply a custom color and highlightColor.
To run the example project, clone the repo, and run pod install from the Example directory first.
JDFNavigationBarActivityIndicator is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "JDFNavigationBarActivityIndicator"
