I’ve come across another excellent “floating” modal view library for iPhone.
What makes this control different is that you have a built in nav bar that has the great look of a native control. The view also adjusts automatically for portrait and landscape orientations.
Here’s a video showing the included demo application in action:
As you can see it looks just like a native component.
You can download the open source control by Hiroki Kokubun known as CQMFloatingController on Github here.
A great option if you need a modal popup containing multiple views.
