If the popover is being displayed when a user taps another interface element such as an image, you should call presentPopoverFromRect instead. The default size of a popover is 320 pixels wide and 1100 pixels tall, but you can easily customize the width and height with the popoverContentSize property. But you may find it interesting that the default 320-pixel width is the same size as the iPhone’s portrait mode width. That’s no coincidence! With that default width, it’s much easier to convert most existing iPhone app views into popovers when creating an iPad version—you won’t need to redesign much (if any) of the view’s original layout.
Since Apple recommends using popovers for user-selectable options, you may wonder why this is the case. There is actually a good reason for this design. Since popovers generally include not only user-selectable items, but also other tappable elements like segmented controls (as shown in Figure 3–4), you don’t want the popover disappearing after just any finger tap. With control over the closing of the popover, you can designate exactly how and when the popover is dismissed based on a user’s selection.
Since this book was designed specifically for iPhone developers, it is assumed that you are already familiar with the Objective-C programming language and the iS frameworks that make up Cocoa Touch. If you’re new to iPhone app development, your first step is to acquire that basic foundation before attempting iPad development, which builds on top of the iPhone development core skill set. Obviously, there’s more to learning Objective-C and Cocoa Touch than can be squeezed into a single chapter. Thankfully, quite a few excellent online resources and books will arm you with the necessary knowledge.
