title: How to adjust space between two UIBarButtonItem in rightBarButtonItems
body: <p>I am using the following codes to add two button to self.navigationItem.rightBarButtonItems, and I think in iOS7, the space between two buttons are too wide, is there a way to decrease the space between these two buttons?</p>
  
  <pre><code>UIBarButtonItem *saveStyleButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"save.png"] style:UIBarButtonItemStyleBordered target:self action:@selector(saveStyle)];
  
  UIBarButtonItem *shareStyleButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(shareStyle)];
  
  NSArray *arr= [[NSArray alloc] initWithObjects:shareStyleButton,saveStyleButton,nil];
  
  self.navigationItem.rightBarButtonItems=arr;
  </code></pre>
  
  <p>Appreciate any hint or idea. </p>
