“‘I’d like to create an integrated television set that is
completely easy to use,’ he told me. [...] ‘It will have the simplest user interface you could imagine. I finally cracked it.’”

The future of TV is iOS

WEBKIT
MULTIPEERCONNECTIVITY
STORAGE LIMITATIONS ▸ app is limited to 200 MB ▸
500 KB of persistent storage (NSUserDefaults) ▸ Use iCloud ▸ Use On-Demand resources
PORTING EXISTING APPS
COCOAPODS ▸ Supports tvOS since 0.39.0 ▸ New platform: platform
:tvos, '9.0'
PODS NOT SUPPORTING TVOS If you are adventurous ! https://github.com/orta/cocoapods-expert-difficulty
SPRITEKIT EXAMPLE
None
DOOM CLASSIC ▸ UIKit changes (UIAlertView, UISlider) ▸ AudioSession isn't
available ▸ Newer C++ compiler
NIBS ! If you don't feel like copy-pasting stuff between
NIBs ! https://github.com/neonichu/bohne
NO DIRECT MANIPULATION
FOCUS ENGINE UIButton().canBecomeFocused() // == true or false UIButton().focused //
== true or false UIScreen.mainScreen().focusedView // nil or the view in focus
DEMO
REACTING TO FOCUS CHANGES func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator)
context.nextFocusedView // the view which gets the focus context.previouslyFocusedView // the view which had the focus func addCoordinatedAnimations(_ animations: (() -> Void)?, completion completion: (() -> Void)?)
CUSTOMFOCUSVIEW class CustomFocusView: UIView { override func canBecomeFocused() -> Bool
{ return true } }
CUSTOMFOCUSVIEW override func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator) { coordinator.addCoordinatedAnimations({
// ... }, completion: nil) }
CUSTOMFOCUSVIEW let duration = UIView.inheritedAnimationDuration() UIView.animateWithDuration(duration, animations: { if context.nextFocusedView
== self { self.backgroundColor = UIColor.redColor() } if context.previouslyFocusedView == self { self.backgroundColor = UIColor.whiteColor() } })
DEBUGGING FOCUS print(view.performSelector("_whyIsThisViewNotFocusable")) e.g. for a UILabel Unmanaged<AnyObject>(_value: ISSUE: This
view has userInteractionEnabled set to NO. Views must allow user interaction to be focusable. ISSUE: This view returns NO from -canBecomeFocused. )
GOOD PLACES FOR BREAKPOINTS func shouldUpdateFocusInContext(_ context: UIFocusUpdateContext) -> Bool
func didUpdateFocusInContext(_ context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator)
GESTURES AND BUTTON PRESSES let tapRecognizer = UITapGestureRecognizer(target: self, action:
"tapped:") let pressTypes = [NSNumber(integer: UIPressType.PlayPause.rawValue)] tapRecognizer.allowedPressTypes = pressTypes; self.view.addGestureRecognizer(tapRecognizer) let swipeRecognizer = UISwipeGestureRecognizer(target: self, action: "swiped:") swipeRecognizer.direction = .Right self.view.addGestureRecognizer(swipeRecognizer)
LOWER-LEVEL API: UIPress Very similar to UITouch-based API in iOS
func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) func pressesEnded(presses: Set<UIPress>, withEvent event: UIPressesEvent?) func pressesChanged(presses: Set<UIPress>, withEvent event: UIPressesEvent?) func pressesCancelled(presses: Set<UIPress>, withEvent event: UIPressesEvent?)
TEXT INPUT
SIRI?
HANDOFF IS ALSO NOT SUPPORTED
https://github.com/rsattar/Voucher
GAME CONTROLLERS
None
SIRI REMOTE IS ALSO A GAME CONTROLLER ▸ Profile GCMicroGamepad
▸ Touch surface is a dpad ▸ Two action buttons ▸ Motion (GCMotion) ▸ Seems not to work in the simulator
NSNotificationCenter.defaultCenter().addObserverForName(GCControllerDidConnectNotification, object: nil, queue: nil) { (note) in if let
controller = note.object as? GCController { if let microPad = controller.microGamepad { microPad.dpad.valueChangedHandler = { (_, x, y) in if let paddle = self.childNodeWithName("Paddle") { paddle.position.y += CGFloat(y) } } } } }
GAME CONTROLLERS WORK WITH UIKIT COMPONENTS
2.27 If your app’s core functionality doesn’t work with the
Siri remote it will be rejected. The app may, however, provide enhanced functionality in connection with a game controller or other peripheral
None
A maximum of two game controllers (plus one remote) can
be connected to an Apple TV at any given time.
DEMO
TVML
CONCLUSION ▸ tvOS works very well ▸ If you know
UIKit, it's easy to start ▸ Think about interaction
