Get refresh icon on swipe down.

I was just wondering, instead of the refresh button staying there, how about using swipe down on the screen to call the refresh button functionality?

Also like the spotlight functionality in iOS, how do I display a button ( or a text field) when I swipe down on the screen?

Thanks a lot in advance.

You could look into the UIScrollViewDelegate methods (such as scrollViewDidScroll), then compare the content-offset to some value, and take action accordingly.

You could also have icons with a negative y coordinate within the scrollview (so that they're above the top of the screen).
