I have a Bar Button Item in the navigation bar of the view (Edit Button). Unlike other buttons (UIButton), I am unable to press ctrl and drag to view controller to create a function to handle it. I want when the button is pressed, a function body to execute.
我在视图的导航栏中有一个条形按钮项(编辑按钮)。与其他按钮(UIButton)不同,我无法按ctrl并拖动来查看控制器以创建处理它的函数。按下按钮时我想要一个要执行的功能体。
How can I link them?

Make sure the button is selected (The view should darken a bit everywhere expect where the button is) and open up the Utilities area. Open the Connections inspector in utilities (an arrow pointing to the right) and under Triggered Segues drag from the circle to your code and create your action.
确保选中该按钮(视图应该在按钮所在的任何位置变暗)并打开“实用程序”区域。打开实用程序中的Connections检查器(指向右侧的箭头),然后在Triggered Segues下从圆圈拖动到代码并创建操作。
