iPhone basic sheet programming?

Question

Hi,

I want to program an "Add"-Window to my application, much like the "Add Contact"-window in the Contacts app or the "Add City"-window in the Weather app.

My question is: how do I code the effect of sliding up that Contacts & Weather feature?

These are called "modal view controllers".

You create a view controller for that "sheet", and from any method of another view controller call

sheetViewController = [[SheetViewController alloc] init…]
[self presentModalViewController:sheetViewController animated:YES];

to slide up the sheet, and from any method of the sheet view controller call

[self dismissModalViewControllerAnimated:YES];

to slide down. Search the term "Modal View Controllers" in the Xcode docs for detail.
