TOKYO (MacHouse) – If you want to convince an Apple reviewer that an app that you are submitting to their App Store is something extraordinary, you’ll have to use a unique feature that might surprise or impress them. Maybe, use a custom progress wheel? So I created something a few weeks ago. And I’ve decided to convert it for Swift 3. That’s where I run into a lot of trouble. Well, it’s finally done. So let’s see what my progress wheel looks like.
My progress wheel consists of eight small circles in slightly different colors. In order to create a rotating wheel like mine, you certainly have to know how to animate UIView. And I use CABasicAnimation for this task since I only intend to rotate the wheel for six seconds. (See Screenshot 2.) As for a view object that encapsulates eight small circles, I have created eight CAShapeLayer objects. That’s all done with a class called CirclesView that I have in my Xcode project.
By the way, as far as eight different gradual colors are concerned, I’ve used a desktop application that I developed just about a year ago. It’s call Text n Colors. I never imagined it would be useful in this sort of situation. GGGGG…
