Drawing Strings
You can draw string objects directly in a focused NSView
using methods such as drawAtPoint:withAttributes:
(to draw a string with multiple attributes, such as multiple text fonts, you must use an NSAttributedString
object). These methods are described briefly in Text in Cocoa Drawing Guide.
The simple methods, however, are designed for drawing small amounts of text or text that is only drawn rarely—they create and dispose of various supporting objects every time you call them. To draw strings repeatedly, it is more efficient to use NSLayoutManager
, as described in Drawing Strings in Text Layout Programming Guide. For an overview of the Cocoa text system, of which NSLayoutManager
is a part, see Cocoa Text Architecture Guide.
