Restored iOS Example animations

[kwridan]

• The sample app had parts of it's animation code commented out
• The view is now also restored to it's original location to create a seamless animation replay

Not sure why the example was commented out, assuming was a mistake ? here's a restoration of it if you find it helpful.

This is not a mistake, because I wanna debug those animation function. And when i complete, I choose not do delete them to precent writing them down again.
