How to add a continuous sinusoidal mask to an iOS image?

Question

I am trying to create a loader framework that will look something like this. But I have little information on how to do this. It is possible to create a sine wave using UIBezierPathand CAShapeLayer. But how can I create a continuous sine wave? Also how to use this as a mask?

Any hint would be a big help.

I would suggest that the designer create a flash file and then convert the flash memory to multiple images. When you have multiple images, use the below lib to show the animation as a loader.
