title: Object library changes using XCode 4 and storyboard
body: <p>When working in the .h or .m of my iPhone app in XCode, the Object Library contains a lot of nice buttons and stuff, i.e. a checkbox, which I would like to add to the interface. But when I enter the storyboard, it changes to just "Objects" and many of the buttons are replaced with view controllers and other stuff. How can I find the Object Library with all the buttons in my storyboard? I wanna add some checkboxes etc in my app. Thanks.</p>
