Under automatic reference counting, why are retain, release, and dealloc not allowed?
I want to release variable in xcode 4.2. When i am releasing it throws me an error. The error is Automatic reference counting forbids explicit message send of 'release'

Below marked answer worked for me and also I couldn't realize that this question has been asked. Anyways happy coding.. :)
This is because you have ARC enabled (Automatic Reference Counting). You can either disable this new feature or learn how to use it. To disable it, click on your project -> your current app target -> Build Settings -> Set Objective-C Automatic Reference Counting to NO.
To learn more about this, you can look at Apple's documentation for Transitioning to ARC.
