Multiple multiline labels

Hi all
I am working on an iphone application that displays a table view [Navigation based]. When user selects a row then the app switches to details view that has four labels with different fonts and sizes placed one above the other in the view. All these labels are multiline. My problem is that when one label has more than two lines of text, it partially overlapps over the next label below it. How can we render all these labels so that if they are multiline all appears properly and with the desired font and size.
In simple words I want to say that If any label has more than one line of text then the next label below it should move by that amount of space so that both will appear with their full text display with no truncation
