最近一个将Objective C 2.0移植到Windows的尝试是Subjective项目。

自述:

Subjective is an attempt to bring Objective C 2.0 with ARC support to Windows. This project is a fork of objc4-532.2, the Objective C runtime that ships with OS X 10.8.5. The port can be cross-compiled on OS X using llvm-clang combined with the MinGW linker. There are certain limitations many of which are a matter of extra work, while others, such as exceptions and blocks, depend on more serious work in 3rd party projects. The limitations are: • 32-bit only - 64-bit is underway • Static linking only - dynamic linking is underway • No closures/blocks - until libdispatch supports them on Windows • No exceptions - until clang supports them on Windows • No old style GC - until someone cares... • Internals: no vtables, no gdb support, just plain malloc, no preoptimizations - some of these things will be available under the 64-bit build. • Currently a patched clang compiler is required; the patch adds -fobjc-runtime=subj flag

该项目可在Github上使用，在Cocotron Group上也有一个线程概述了一些进展和遇到的问题。

另外:

Cocotron是一个开源项目，旨在实现一个类似于苹果公司Cocoa文档所描述的跨平台Objective-C API。这包括AppKit, Foundation, Objective-C运行时和支持api，如CoreGraphics和CoreFoundation。

你可以在Windows环境中使用Objective C。如果你按照以下步骤操作，它应该可以正常工作:

Visit the GNUstep website and download GNUstep MSYS Subsystem (MSYS for GNUstep), GNUstep Core (Libraries for GNUstep), and GNUstep Devel After downloading these files, install in that order, or you will have problems with configuration Navigate to C:\GNUstep\GNUstep\System\Library\Headers\Foundation1 and ensure that Foundation.h exists Open up a command prompt and run gcc -v to check that GNUstep MSYS is correctly installed (if you get a file not found error, ensure that the bin folder of GNUstep MSYS is in your PATH) Use this simple "Hello World" program to test GNUstep's functionality: #include <Foundation/Foundation.h> int main(void) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; NSLog(@"Hello World!."); [pool drain]; return; } Go back to the command prompt and cd to where you saved the "Hello World" program and then compile it:2 gcc -o helloworld.exe <HELLOWORLD>.m -I /GNUstep/GNUstep/System/Library/Headers -L /GNUstep/GNUstep/System/Library/Libraries -std=c99 -lobjc -lgnustep-base -fconstant-string-class=NSConstantString Finally, from the command prompt, type helloworld to run it

祝一切顺利，并在Objective-C中玩得开心!

注:

我使用默认的安装路径-相应地调整您的命令行 确保您的文件夹路径与我的文件夹路径相似，否则将报错

你可以在这里得到一个objective - c编译器，它可以在Windows上工作，并且在Visual Studio 2008\2010上运行良好。

open-c争吵

只需下载最新的源代码。你不需要构建所有的CF-Lite有一个解决方案叫做objc.sln。您将需要修复一些包括路径，但它将构建良好。甚至还包含了一个测试项目，这样你就可以看到一些objective-c .m文件正在visual studio中编译和工作。可悲的是，它只适用于Win32而不是x64。需要为x64编写一些汇编代码来支持它。
