title: Why does UIBarButtonItem not show the Image on Iphone 4
body: <p>I'm trying to add a reload button to my navigation bar using this code</p>
  
  <pre><code>- (void)viewDidLoad 
   {
  
     [super viewDidLoad];
  
     UIButton *butt = [UIButton buttonWithType:UIButtonTypeCustom];   
     [butt setImage:[UIImage imageNamed:@"reload.png"] forState:UIControlStateNormal];
     [butt addTarget:self action:@selector(reloadNews) forControlEvents:UIControlEventTouchUpInside];
  
     UIBarButtonItem *reloadButton = [[UIBarButtonItem alloc]initWithCustomView:butt];
     self.navigationItem.rightBarButtonItem = reloadButton;
     [reloadButton release]; 
  
  }
  </code></pre>
  
  <p>which work fine on iPhone 3GS device (with iOS4) but doesn't show the png on simulator and iPhone 4 device (iOS4 as well). 
  Any ideas?</p>
  
  <p>BTW: It's independent of how I hold the Phone ;-)</p>
