title: How to add an action on button touch up in iOS storyboard
body: <p>I am new to iOS app development. I am going through the dev guides. My app has two views - one with a button and clicking that button launches a new view. I added a segue to launch the new view and was able to link it to the button. But its not clear to me what the exact action that launches the new view and how I can handle that action. I want to do some network operation before launching the new view and so want to handle that button click event (touch up). Can I get Xcode to generate a dummy handler function for that specific event?</p>
