swift - 如何将 barButtonItem 添加到工具栏

Question

如何转换此代码以使该按钮出现在工具栏中？ :

navigationItem.rightBarButtonItem = editButtonItem()

Answer 1

试试这个，

    let barButtonItem = UIBarButtonItem(title: "Edit", style: .Plain, target: self, action: "onEditButtonTapped:")
    self.navigationItem.rightBarButtonItem = barButtonItem

然后像这样编写 Action 函数，

    func onEditButtonTapped(sender:UIBarButtonItem) {
        ...
    }
