问题
After I updated to Xcode 4.2, I can no longer release anything. When I start typing "release" it suggest "release" but with a red line across.
If I write it anyway it shows an error and displays these two messages:
'release' is unavailable: not available in automatic reference counting mode Automatic Reference Counting forbids explicit message send of 'release'
Does anyone know what I can do?
回答1:
You need to turn off Automatic Reference Counting. You do this by clicking on your project in the navigator (the top item in the finder-like thing on the left), then click on your target, select "Build Settings" and turn off the option "Objective-C Automatic Reference Counting" (you can use the search field on the upper right to search it).
Another possibility is to migrate your project to ARC.

Thanks... its CLANG_ENABLE_OBJC_ARC .. you need to make it NO available under Build Setting. Actually I got this error after updating to Cordova from Phonegap. I hope I wont get into more troubles by doing so.. Cheers.. Happy Coding!!
