There are various types of spinning indicator in various type of apps and webpages. While not all, many of them can be recreated by using CAReplicatorLayer.

Although CAReplicatorLayer is cool, originally I don’t know what can it be used for, until I found this great article from David Rönnqvist that is to create spinning indicator.

By using QuartzCode, this spinning indicator can easily be created. By using combination of CAReplicatorLayer and other animation properties, there are numerous possibilities of what can be done.

In the following video I’m gonna show you how to create custom activity indicator without using any image and code.
