Thanks, Jake. I will write a wiki page after holidays.
> Add support of ARC to Objective-C
> ---------------------------------
>
> Key: THRIFT-1340
> URL: https://issues.apache.org/jira/browse/THRIFT-1340
> Project: Thrift
> Issue Type: Improvement
> Components: Cocoa - Compiler, Cocoa - Library
> Affects Versions: 0.7
> Environment: Mac OS X Lion, iOS 4.2, 4.3, 5.0..
> Reporter: HIRANO Satoshi
> Assignee: HIRANO Satoshi
> Fix For: 0.9
>
> Attachments: THRIFT-0.8.0-dev_cocoa_ARC.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Objective-C in Xcode 4.2 supports ARC (Automatic Reference Counting, not GC
> but similar) and now it is the default both on OS X Lion and iOS 5. (ARC
> works on iOS 4.2 or higher.)
> The conventional Objective-C code includes many retain/release/autorelease
> for maintaining the life time of objects.
> Since the latest Objective-C compiler automatically generates stubs for
> reference counting, code should not include any retain/release/autorelease.
> Many Mac OS/iOS projects are moving to ARC mode. Although we can specify a
> compiler flag which tells ARC or no-ARC file by file in Xcode 4.2, there is
> no means to tell the Xcode that files generated by the thrift compiler are
> no-ARC. Xcode produces many error messages like "retain is not allowed in ARC
> mode".
> So, the thrift compiler should support ARC mode.
> What we need are:
> 1) add -objc-arc flag to the thrift compiler.
> 2) If -objc-arc flag exists, omit generating code for
> retain/release/autorelease.
> Please look at "Programming with ARC reference notes" in iOS developer
> library.
