2. What is a storyboard? A collection of views and the transitions between them. May contain all the views in an app or a subset. A necessity for rapid UI development. Great for prototyping. A picture is worth a thousand lines of code.
3. How do UIStoryboards compare to XIBs? UIStoryboard: Interface Builder IBOutlets/IBActions Segues Static cells Prototype cells XIB: Interface Builder IBOutlets/IBActions
4. What is a segue? Not the cool, two-wheeled mobility device invented by Dean Kamen. A transition from one view controller to another. Alternatively can present a popover.
5. -prepareForSegue:sender: Called on the source view controller before the transition happens. The segue keeps track of the destination view controller. Use this method to pass data on to the destination view controller.
6. How do I get data back? Delegate Block Notification center Observer Shared data
7. Types of segues Push Modal All standard modal transitions are supported. Popover (iPad only) Custom Any transition you want.
8. Static cells Used for table views that always look the same. No need for a UITableViewDataSource nor a UITableViewDelegate. May eliminate the need for a UITableViewController subclass.
9. Prototype cells Custom UITableViewCells associated with a UITableView. Makes it easy to create and use custom cells. Usually requires a custom cell class. May eliminate the need for a UITableViewDelegate.
10. Other advantages Keeps similar views together. Gives a bird’s eye view of the app. Makes the view hierarchy easier to analyze. Saves a lot of coding.
