title: iPhone init method issue
body: <p>I created a property for the NSArray which creates a getter/setter.  I know Apple recommends using the instance variable in the init and dealloc method.  I'm trying to figure what to do in the following code.</p>
  
  <p>(1) Do I need an extra release statement? Wouldn't array have a retain count of 2 then 1 with the dealloc, leave a leak.  Or would autorelease take care of this?</p>
  
  <p>(2) Is there some way in xCode or instruments to follow a specific variable to see its retain count going through the process. </p>
  
  <pre><code>@property (nonatomic, retain) NSArray *array;
  
  @synthesize arrary = _array;
  
  - (id)initWithNibName:(NSString *)nibNameOrNil 
                 bundle:(NSBundle *)nibBundleOrNil 
          initWithArray:(NSArray *)array
  {
      self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
      if (self) {
  
          _array = [[NSArray alloc] initWithArray:array];
  
      }
      return self;
  }
  
  - (void)dealloc
  {
      [_array release];
  
      [super dealloc];
  }
  </code></pre>
