2. The Basics: Views • ViewControllers manage View(s) • Each VC manages a portion of your app’s user interface. • Each can manage interactions between that interface and the underlying data.
4. • ViewController classes can be subclasses of UIViewController, UICollectionView, UITableView, SplitView’s, etc. • You can embed ViewController’s Views within other ViewController’s. (parent, child, children). • You should experiment with each. • We won’t be getting into any of the above today.
5. UI… uh what? • Apple often releases Sample Code • Searchable Index: http://apple.co/1DaX9or • UI Catalog http://apple.co/1pOo4Yf is GREAT for learning basic UI Controls and how to work them.
6. Back to Views for a bit
7. Views have frames • Origin (x,y) at the top left • Height & Width • “Coordinate system orientation in UIKit”
8. In practice • Constraint (limits the space from the top of the view the top of the UIImageView
9. Enough boring stuff. Let’s get to it.
10. Make an app • Remember “Hot or Not”? • We’ll make one for Easter; pick the cute bunny. • It’ll have a very basic UI. • And we’ll write unit tests to verify it.
11. The general layout • Picture to view • Buttons to vote
