How to use Control drag in Xcode
提问by Saurabh Hooda
I am just starting off with iOS development. I am trying to add action to a button and it is mentioned on apple developer site that "To Control-drag, press and hold the Control key while you drag from the button to the implementation file in the assistant editor pane." But am not able to do this. What is control key? How can i do this? When I try to add control drag, entire button is getting dragged and am not able to see any control-drag arrow. Thanks a lot for your time.
我刚刚开始使用 iOS 开发。我正在尝试向按钮添加操作，在苹果开发人员网站上提到“要控制拖动，请在从按钮拖动到助手编辑器窗格中的实现文件时按住 Control 键”。但我无法做到这一点。什么是控制键？我怎样才能做到这一点？当我尝试添加控制拖动时，整个按钮都被拖动并且看不到任何控制拖动箭头。非常感谢您的时间。
