Answer 1

Your label is not updating because , you are trying to call updateLabel method with a new instance.

You should call updateLabel of the original instance of viewcontroller from which you have presented your modal view.

you can use a delegate mechansim or NSNotification to do the same.

Delegate mechnaism would be clean. NSNotification is quick and dirty.
