Question

Not quite sure how to phrase this, but should I release a variable in this situtation:

NSString *string = @"HELLO WORLD";
NSArray *array = [NSArray arrayWithObject:string];  
NSString *shouldIReleaseThis = [array objectAtIndex:0];
NSLog(@"%@", shouldIReleaseThis);
//????  [shouldIReleaseThis release] ??????

//Do stuff with array

Should I release it? Why or why not?

You don’t own it (you didn’t get that reference from new, alloc, retain or copy), so you shouldn’t release it. See Apple’s memory management programming guide for a brief but complete overview of the memory management rules in Cocoa.
