### CoreTextPageViewer ### |
=========================================================================== |
DESCRIPTION: |
This sample shows how to use CoreText to display large amounts of text on a page |
basis using a flexible frame structure. |
This sample is based on a sample used for WWDC 2010, Session #110, "Advanced Text Handling |
for iPhone OS". The session can be viewed at <http://developer.apple.com/videos/wwdc/2010/> |
To use this sample, you may select from a list of example documents via the |
"Samples" list, and you may make document-wide overrides of the used font and |
font features via the "Fonts and Features" list. To paginate through an example |
document, swipe left or right. Note that while some fonts support applying multiple |
font features simultaneously, for simplicity this sample only allows setting |
one font feature override at a time. |
Please see the ReadMe.xml sample document in this sample itself for more |
details on the application architecture. |
=========================================================================== |
BUILD REQUIREMENTS: |
OS X 10.8, iOS 7.0 SDK |
=========================================================================== |
RUNTIME REQUIREMENTS: |
iOS 6.0 or later, iPad only |
=========================================================================== |
PACKAGING LIST: |
AppDelegate.{h,m} |
A simple application delegate to display the application's window. |
RootViewController.{h,m} |
The root view controller that manages the main Core Text scroll view and popovers. |
SamplesController.{h,m} |
A table view controller to manage and display a list of file names of sample documents to draw. |
FontFamsController.{h,m} |
A table view controller to manage and display a list of font families to use, and supported |
font features. |
AttributedStringDoc.{h,m} |
Manages the construction of AttributedStrings from xml/plist documents. These documents are generated on Mac OS X using the AttributedStringDoc Gen sibling project to this demo. It takes an RTF document created using TextEdit, reads it into an AttributedString, and finally proceeds to serialize it into a format (xml/plist) that is readable by the AttributedStringDoc class. In fact, the AttributedStringDoc class is also used on the desktop to serialize the file. |
This class also keeps track of the characteristics of the document: background colors, frames for each page, page number display, and number of columns to display. |
CoreTextScrollView.{h,m} |
Manages the display of pages for a given document to display. This is the view that you will use in Interface Builder or create directly to display and interact with an AttributedStringDoc in an application. |
It is also fair to say that this view acts as a controller for CoreTextViews. You can change the page to display, manage text selection, and change font parameters for the document. |
TextAccessibilityElement.{h,m} |
This class defines the Accessibility features for CoreTextScrollView. |
