Answer 1

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.

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.
