Question

I’d like to extend a class from UIImageView,which will infinite rotate a universe image. So I can simply put this image view as background view for other UI elements.

3 questions here:

1. Is it the right way to extend from UIImageview class.
2. How to keep rotating infinite, and as background, when put it into other views, I don’t need to write extra lines of code.
3. I wrote a rough prototype, when I put it into other views as background, all UI elements in this view are rotating with the image.

Answer 1

1. There is nothing wrong in extending UIImageview Class.
2. Create rotation animation and set repeat ON.
3. Do not add element on rotating image. (Add elements in base view. Insert rotating imageview at index 0).
