Native dynamic height calculation for UIViews in Titanium Mobile SDK. Useful for situations where getSize(), getRect() or postLayout event is not sufficient. Typically needed when view dimensions are set to Ti.UI.FILL or Ti.UI.SIZE. Add this method to TiUiLabelProxy.m, TiUITableViewProxy.m Reference: http://developer.appcelerator.com/question/14…
