xcode potential leak of an object stored into "array"

NSArray * array = [[[NSUserDefaults standardUserDefaults] objectForKey:@"Top"] mutableCopy];
NSString * cellValue = [array objectAtIndex:indexPath.row];

and I get this error:

potential leak of an object stored into "array"

How can I fix this without migrating to ARC. Please help, and thanks a million in advance!

Because you're creating a new object (methods with copy give object with reference count 1) you need to release it.

The error refers to the array stored in the array variable. If you're not using it outside this function or you're later assigning it to a property that would retain it, then autorelease it:

 NSArray *array = [[[[NSUserDefaults standardUserDefaults] objectForKey:@"Top"] mutableCopy] autorelease];
