I can’t understand why a memory leak occurs here.

Question

I have the following block that gives me problems in the performance tool: in particular, it says that STObject is leaking. I'm not sure why?

for (NSDictionary *message in messages)
{
    STObject *mySTObject = [[STObject alloc] init];

    mySTObject.stID = [message valueForKey:@"id"];

    [items addObject:mySTObject];
    [mySTObject release]; mySTObject = nil;

} 
[receivedData release]; receivedData=nil;
[conn release]; conn=nil;

UPDATE:

is this a property of @property (non-atomic, conservation), will this result in a hold value of +2?
