iPhone Leak while reading string value

Instruments tools says this is a leak, any ideas?

I release the variable object by end of the for loop

and by the begininng of the method above this is how I set the variables obkect, thats autorelease;

NSMutableArray *variables = nil; 
if (self.responseXMLData) {
    variables = [NSMutableArray arrayWithCapacity:10];
            //here is the al开发者_如何学运维l the code in the if statement which posted the screen shots

To all the new readers, after the edit to the question; this isn't the answer !

Yes.

You don't release variables anywhere.

You call alloc] init] so it's your responsibility to release it :)

Make sure you are releasing self.variables property in your dealloc (or somewhere). Also, ensure that your Variable class is releasing variableValues property in the Variable class's dealloc.
