MacDev.GarbageCollectionIsDeprecated-WhenXcodeCompileMacAppProject
Garbage Collection is not supported
当Xcode编译Mac OSX App时报错:"Garbage Collection is not supported
" 的解决办法:
1. 不需要迁移到ARC仍然可以编译通过
"If your project is imported from Xcode 3.x and you want to use ARC, you will have the following error at compile time :

|
Garbage Collection is deprecated ; use the "Convert to Objective-C ARC" menu command to switch to Automatic Reference Counting |
To get rid of this, edit the project and remove anything you see under GCC_ENABLE_OBJC_GC.
This will remove the -fobjc-gc parameter from the gcc commands and you will be able to use the smart ARC." Ref[2]
2. Mac Apps不能再使用garbage collection
"Beginning May 1, 2015, new Mac apps and app updates submitted to the Mac App Store may no
longer use garbage collection, which was deprecated in OS X Mountain Lion. Instead, migrate
your apps to Automatic Reference Counting, using the migration assistant in Xcode to help with this transition.
Apps may continue to use retain/release for manual memory management. For more information,
read theTransitioning to ARC Release Notes." Ref[1]
