您可以使用自定义按钮自定义您的右栏按钮项目。

//custom back button 
    button = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [button setBackgroundImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal]; 
    [button addTarget:self action:@selector(backButtonClicked) forControlEvents:UIControlEventTouchUpInside]; 
    [button setFrame:CGRectMake(-2, 0, 52, 30)]; 

    UIBarButtonItem *btnItem = [[UIBarButtonItem alloc] initWithCustomView:button]; 
    self.navigationItem.rightBarButtonItem = btnItem; 
    [btnItem release];
