iphone - 导航栏在新联系人页面上不可见

Question

我想在按钮点击时显示新的联系页面我已经在操作按钮中编写了这段代码

{  
    ABNewPersonViewController *abnewpersonviewcontroller = [[ABNewPersonViewController alloc] init];   
    [self.navigationController pushViewController:abnewpersonviewcontroller animated:YES];
    [newPersonController release];
 }
