问题描述
当我创建我的项目时，我支持 ARC ，所以我的项目将支持iOS 4.3及更高版本。
When i created my project, i made it to support ARC, so my project will support iOS 4.3 and above.
现在我需要整合Twitter和Facebook。公司提供的Facebook和Twitter框架都不支持 ARC 。
Now i need to integrate Twitter and Facebook to it. Both Facebook and Twitter frameworks given by the companies does not support ARC.
大多数文件都有dealloc，释放其变量。有人说要废弃项目，并重新启动ARC。但是，我不能这样做，因为我做了大部分的事情。
Most of the files have dealloc, and released its variables. Some say to scrap the project and redo it disabling ARC. But, i can't afford to do this, since i have done most of the stuff.
我添加了 FBConnect 文件（其中有4个），并添加 -fno-objc-arc ，如。仍然我得到
I added the FBConnect files (there were 4 of them) and added -fno-objc-arc as described in this tutorial. Still i get
file://localhost/Users/illepmorgan/Documents/Projects/illep/untitled%20folder/alphaproject/alphaproject/FBRequest.m: error: Automatic Reference Counting Issue: Existing ivar '_delegate' for unsafe_unretained property 'delegate' must be __unsafe_unretained
我需要帮助，我不能重做这个。
I need help, i can't redo this again.
推荐答案
确保你添加了-fno -objc-arc标志到每个实现文件（.m文件）。
Make sure that you added the -fno-objc-arc flag to each implementation file (.m file).
然后清理项目（项目菜单 - >清洁）并重新构建。在上课时，我有时不得不清理两次。似乎像一个小bug。
And then clean the project (Project menu -> clean) and build again. I have sometimes had to clean and build twice when doing this in class. Seems like a little bug.
