NSObject.m的源代码在哪里？ [英] Where is the source code for NSObject.m?

问题描述

我试图找到 NSObject.m 的来源。 （我想比较 retain 和 release 的前后ARC实现。）

我已查看 http://www.opensource.apple.com/ 和< a href =http://www.macosforge.org/> http://www.macosforge.org/ ，但无法找到。

NSObject 的源代码。

http：// www .opensource.apple.com / source / objc4 / objc4-532 / runtime / NSObject.mm

整个Objective-C运行时包可以从 http://www.opensource.apple.com/tarballs/objc4/objc4-532。 tar.gz

回顾一下网站上运行时软件包的以前版本，会出现 NSObject.mm 文件只包含在最新的软件包中。

I'm trying to find the source for NSObject.m. (I want to compare the pre and post ARC implementations of retain and release.)

I've looked on http://www.opensource.apple.com/ and http://www.macosforge.org/ but not been able to find it.

解决方案

The source code for Apple's NSObject is contained in the Objective-C runtime package on Apple's open source repository site.

http://www.opensource.apple.com/source/objc4/objc4-532/runtime/NSObject.mm

The whole Objective-C runtime package can be downloaded from http://www.opensource.apple.com/tarballs/objc4/objc4-532.tar.gz

Looking back through the previous versions of the runtime package on the site it appears the NSObject.mm file is only contained in the most recent package.
