查看@synthesize为getter / setter生成的代码 [英] Viewing the code generated by @synthesize for getter/setter

问题描述

是否可以查看@synthesize生成的确切代码？

解决方案

生成getter和setter方法的C ++代码：

http://llvm.org/svn/llvm-project/cfe/trunk/lib/CodeGen/CGObjC.cpp

您还可以在应用运行时实现。虽然不是字面上与生成的代码相同，但是这个代码更容易阅读，并清楚地表明适当的getter和setter应该做什么。

Is it possible to view the exact code generated by @synthesize?

解决方案

You can read the Clang compiler source to see the C++ code that generates the getter and setter methods:

http://llvm.org/svn/llvm-project/cfe/trunk/lib/CodeGen/CGObjC.cpp

It's pretty cryptic but that's the most accurate way of seeing the code generated.

You can also look at the objc_getProperty and objc_setProperty implementations in Apple's runtime implementation. While not literally the same as the code that is generated, this code is much easier to read and gives a clear indication of what a proper getter and setter should do.
