iOS layout positioning now respects native properties like automaticallyAdjustsScrollViewInsets, edgesForExtendedLayout, extendedLayoutIncludesOpaqueBars, navigationBar.translucent, tabBar.translucent
Removed frame-tests.ios.ts - those tests are now invalid
Added new layout tests inside page-tests.ios.ts
Commented few asserts in scroll-view-tests
View now expose ios namespace with layoutView method and UILayoutViewController used by page, tab-view and application module
ViewBase now expose viewController property that should be set from all widgets that are using viewcontrollers internally (like Page, Frame, TabView)
ViewBase now sets ios property to either the view returned from createNativeView or to nativeViewProptected
fragment.transitions now use animation/transition start to add fragments to waitingQueue. Before we did it manually in navigate/goBack. This way we can reuse the fragment.transition when calling showDialog. Also when animation/transition ends we check the animation/transition to see if this fragment should be set as current.
Frame expose new loadViewFromEntry method (to load a view from URI)
Frame navigation happens once frame is loaded
Frame now supports Page as a child in XML
Fixed GridLayout row, rowSpan, column, columnSpan properties type
Fixed bug in GridLayout where add/remove of columns/rows won't update the internal state of the grid (backport from android when GridLayout is recycled)
ListView will no longer invalidate layout when cell is removed
Fixed bug in ScrollView ios where effectiveMinWidth/Height was multiplied to density (it is already on device pixels so no need to multiply)
TabView android now calls loaded only on the selected child (not all)
Core refactoring
recycleNativeView filed now accepts: "always" | "never" | "auto". Always will recycle the nativeView no matter if its nativeView or android proprties are accessed. Never will disable recycling. Auto will recycle it only if nativeView and android properties are not accessed.
Less than 30 erros left, let's hope it still works
Added lib.*.d.ts from typescript, removed lib and dom stuff, added by hand XHR, alert etc. .d.ts-es for polyfills
Roll back some changes involved in separating UIEvent for dom and ios
Test combined dts-es will now use lib, while internally we will not to avoid UIEvent conflict with dom stuff
Added View.isLayoutRequired - to check if Layout call is needed after a measure call. Use in list-view.
Measure pass now get all its properties from nativeLayoutParams property instead of using instance dependency properties (e.g. perf improvement).
List-view now layouts cells only if there is need to.
List-view now measure rows with the specified rowHeight.
