Not released value

Reports the owned objects stored in the local variables or parameters that are not released later or are overwritten by another value before they are released.

 - You take ownership of an object if you create it using a method which name begins with alloc or new or contains copy, or if you send it a retain message.

 - You use release or autorelease to relinquish ownership of an object.

Objective-C memory management rules require each owned object to be released or autoreleased, see Memory Management Programming Guide.

If ARC (Automatic Reference Counting) is on, this inspection is disabled.
