UIAlertView

UIAlertView is a class to display alert messages on screen.

Showing with Undo dialog animation

Signature	-(void)showWithAnimationType:(int)type;

Unlike all other dialogs which pops up, the Undo dialog appears by jiggling in from the side. You can do so with [alert showWithAnimationType:1].

You can create multiple text fields using the -addTextFieldWithValue:label: method. If you only need 1 text field, using the -textField method will automatically create only 1 for you. When the alert view has text fields, it will only be available in portrait position.
