You're violating principals of MVC. Views should never talk directly to one another. If you need to signal some change in one view upon some event from another view, you need to route it through your controller.

I.e., a push of a button might change a label. In this case, the button receives an event (touches up or whatever) which get routed through its delegate (some controller). This delegate can then signal some action which then changes the text of the label (the second view).

I strongly suggest you become acquainted with the model-view-controller paradigm. It will give you insight into how the frameworks are constructed, and enable you to better write code targeting these frameworks.
