推荐答案
您不能直接在导航栏上设置项目,需要仔细阅读
contacts.navigationItem.leftBarButtonItem = yourItem;
You can't set the items on a navigation bar directly, you need to go through the navigation item, which you get from the view controller your displaying in the navigation controller. So, contacts.navigationItem.leftBarButtonItem = yourItem;
