You shoud have:

a root UIScrollView
a programmatically-created UIView for every icon
to iterate through the icons use [root subviews]
an animation function shakeView:(UIView *)paramView that adds the delete icon and starts shaking the icon
a global bool isShaking to have the state of the screen

Use touchesBegan to detect the view that is clicked/selected and the type of touch

That about sums it up. Try to create a maximum amount of elements programmatically.

Are you sure each icon should be its own UIView? It would be more lightweight to have a CALayer for each icon and then assign the `CGImageRef` of the icon to each layer. But as usual, one has to profile it, if it is worth the optimization. – GorillaPatch Apr 07 '11 at 09:12
It's the structure I used and it works flowlessly on iPhone 3G and higher. – Stefan Ticu Apr 07 '11 at 09:21
Thanks for the comment. I asked because on the mac a `NSView` is quite a hefty class which could lead to performance degradation. In UIKit `UIView` is obviously much more resource friendly. – GorillaPatch Apr 07 '11 at 09:23

There is no harm if you take a look at this:

Move UIViews to avoid collision like rearranging icons on Springboard

Unfortunately Apple doesn't provide a GridView Class, but you can use the very handy TTLauncherView from Three20 that implements all the default behaviour for you:

From their website http://three20.info/

Three20 is a open source Objective-C library used by dozens of well-known brands in the App Store, including Facebook, Posterous, Pulse, Meetup.com, and SCVNGR. Three20 provides powerful view controllers such as the Launcher, the popular Photo Browser, and internet-aware tables.
