UIButton *homeBtn=[[UIButton alloc] initWithFrame:CGRectMake(0, 0, 46, 28)];
[homeBtn setBackgroundImage:[UIImage imageNamed:@"homeBtn.png"] forState:UIControlStateNormal];    
[homeBtn addTarget:self action:@selector(homeBtnPressed) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *navHomeBtn=[[[UIBarButtonItem alloc] initWithCustomView:homeBtn] autorelease];    
self.navigationItem.rightBarButtonItem=navHomeBtn;   
[homeBtn release];
