Update a tabView from within another tab?
<p>I am having trouble with the tabBar:didSelectItem: in my app...
I have 4 tabs and 1 of them is a settings tab that updates a plist file with the settings on save. </p>

<p>What I want to do is to run an action, when another tabbar item is selected, so I can update the view with the appropriate settings. I just can't get this to work. Can anyone please show me an example on how to use the tabBar:didSelectItem: in this way, or maybe another way to do it? Thanks...</p>
