Answer 1

Basically what you need to do is add a "cover page" view over your current view.

These usually work best if you set the alpha to about 50%.

Hitting the button you can call addSubview:coverPage where you init coverPage somewhere with the right attributes.

If you want, cover page can have it's own spinners or labels if necessary.

after your refresh completes, just call [coverPage removeFromSuperview] to dismiss.

Answer 2

UIActivityIndicatorView is the spinning thing that is the default busy indicator. It inherits from UIView. If you subclass it and have your own drawRect: implementation you should be able to draw any image you like in place of the spinning bars.
