title: Navigation Bar or ToolBar trouble in xcode
body: <p>Ok I was looking at the iPhone iCal app, and was curious whether that top bar is a navigation bar or a toolbar? ive tried using both, but also i cannot figure out how to change the size of the buttons to be as small as the + button in the top right... very confused.. I'm assuming its a navigation bar, but when i read the description of the navigation bar, it said that whenever you are to add a button or item onto the bar, you cannot connect it directly... no idea how else to do it... but anyone wanna help with this issue?</p>
