Using Non-ARC Code in an ARC-Enabled Project - Adding Facebook
Solution 1
Make sure that you added the -fno-objc-arc flag to each implementation file (.m file).
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.
Solution 2
there is actually a much easy way working in mixed ARC and Facebook none ARC . see my post on how to use it http://nabtech.wordpress.com/2012/02/02/facebook-ios-sdk-and-arc/

Illep almost 2 years
When i created my project, i made it to support
ARC
, so my project will support iOS 4.3 and above.Now i need to integrate Twitter and Facebook to it. Both Facebook and Twitter frameworks given by the companies does not support
ARC
.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.
I added the
FBConnect
files (there were 4 of them) and added-fno-objc-arc
as described in this tutorial. Still i getfile://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
I need help, i can't redo this again.

Illep over 12 yearsYou will also have to add the JSON files (which are in a folder). So do i have to add the flag for those files as well ? The JSON files were not identified in the
target
to add the flag. What should i do now ? -
Firoze Lafeer over 12 yearsJSON files are not objective-c code, and you won't compile them, so this flag doesn't apply.

Illep over 12 yearswell,
FBConnect
the Facebook framework has aJSON
folder and when you look in that you will find a lot ofObjective-C
code. So do i have toflag
them too ? -
Firoze Lafeer over 12 yearsYes, any objective-c implementation files (.m), regardless of folder.
