如何将barButtonItem添加到ToolBar

Question

如何转换此代码以使按钮显示在工具栏中？ ：

navigationItem.rightBarButtonItem = editButtonItem()

Answer 1

试试这个，

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

然后编写动作函数，就像这样，

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

Answer 2

试试这个：

    self.navigationItem.setRightBarButtonItem(UIBarButtonItem(barButtonSystemItem: UIBarButtonItemStyle.Plain, target: self, action: "btnClicked:"), animated: true)


  //adding function to bar button

    func btnClicked(sender: UIBarButtonItem)
     {
        //your code here
     }
