为什么 iPhone 上没有 NSAttributedString?

Why No NSAttributedString on the iPhone?(为什么 iPhone 上没有 NSAttributedString?)

问题描述

Does anyone know what made Apple leave out NSAttributedString when turning AppKit into UIKit?

The reason I ask is that I would really like to use it in my iPhone app, and there appears to be no replacement or alternative than doing it myself...

It is possible to have mixed font attributes on a string - it's just a hell of a lot of work to to achieve something similar that was possible with a few lines of code with NSAttributedString.

Also, doing all this extra drawing code myself makes my table view cells really heavy, and really hurts performance.

Anyone got any ideas? Any genius's working on an opensource alternative to NSAttributedString?

NSAttributedString is now on the iPhone as of 4.0 Beta
