multiple instances of a short when switching between uiviewcontrollers

[sregorcinimod]

I have two UIViewcontrollers (A and B) and within UIViewController A i have two "short" variables called C and D, and a method called E.

In the method E it uses D as a counter and loops round until it is the number 3 at which point it loads an image. clicking on the image loads UIViewController B.

When UIViewController B switches back to UIViewController A there are two instances of the shorts, one with the values set in viewDidAppear of UIViewController A (which I want) and one instance holding the values from the first time UIViewController A is used.

I have cheked this by simply putting in an NSLog to show the current value of C and D, the second time UIViewController A is dislayed I get two NSlog messages for each short.

Note: I am switching viewcontrollers by using PresentModalViewController.

Any ideas?

Post code.

modal controllers aren't really a switching mechanism. You present a new controller while the calling controller remains loaded underneath. To go back you don't present the first one again, but dismiss the modal one. In any case, without seeing code we can just guess.
