(Dynamic Type) – Auto Layout – sizeThatFits: is height for width – table.View.rowHeight =44 (gotcha) – tableView.estimatedRowHeight = 44

Gestures, Fast JavaScript • Powerful integration for Hybrid Apps: • Navigation Delegate • User scripts • Script Messages – JSON" – window.webkit.messageHandlers.<name>.postMessage();"
WKWebView
Modern Objective - C • instanacetype – (instancetype)initWithFrame:(CGRect)frame; " •
Properties vs. method notations ! !"

– Website Links – Campaign Links • App Bundles – Only for paid apps – Complete my bundle
App Previews • 30 Seconds • Shows UI/Functionality • Easily
Capture - OS X Yosemite and iOS 8 • Can Do: – Narrations • Don’t Do: – Hands – Prices – Copyright infringement
