title: How to disable Xcode4.2 Automatic Reference Counting
body: <p>Today, I have update my xCode to 4.2 version,  And I want to disable the ARC,  I also search with the google.  but can't fix my problem. According the search results, In the target setting,  I can't find the 'Objective-C Automatic reference counting' item,  So have no chance to set it to NO.  I find the item one by one,  and also use the search field.</p>
