How to enable/ disable “Automatic Reference Counting”?

Question

Using Xcode 4.2, how can one enable/disable \"Automatic Reference Counting\"?

ANSWERED Under Build Settings, flip \"yes\" and \"no\" depending whet

Answer 1

In XCode 4.6 this property has now changed to CLANG_ENABLE_OBJC_ARC

Answer 2

Globally:

Go to "Build Settings", look for "Apple LLVM compiler 3.0 - Language". Set the field "Objective-C Automatic Reference Counting" to "No".

For individual files:

Go to "Build Phases", select the file, double-click the "Compiler Flags" column and put "-fno-objc-arc" in it.

Answer 3

To enable ARC per-file, you can also set your "Compiler Flags" under "Build Phases" to -fobjc-arc. Make sure your compiler is set to Apple LLVM compiler 4.x and not LLVM GCC 4.2.
