iOS 7 introduced "Text Kit," a broad set of APIs and modifications of existing classes, built on MonoTouch.CoreText, that greatly expands the typographical flexibility of iOS.

The MonoTouch.UIKit.NSLayoutManager's NSLayoutManager.TextStorage property holds a reference to a MonoTouch.UIKit.NSTextStorage object, that holds a potentially large amount of styled text. The MonoTouch.UIKit.NSLayoutManager's NSLayoutManager.NSTextContainers property holds an ordered array of MonoTouch.UIKit.NSTextContainer objects in which it lays out text. The MonoTouch.UIKit.NSTextContainers, in turn, hold references to MonoTouch.UIKit.UITextView objects, which actually display the text.
