UINavigationItem上的touchUpInside事件

Question

In my app's main view, I have a button that segues to a subclassed UINavigationController holding a UITableViewController to change settings.

To get back to the app's main view, I have this in the UINavigationController subclass:

navigationBar.setItems([UINavigationItem(title: "Back"), 
                        UINavigationItem(title: "Settings")], 
                        animated: false)

When I tab the Back button, the app segues back to the same view - but the navigation bar now only have the Settings item.

When I click the Back button, I want to dismiss the UINavigationController subclass and come back to my main view.

So how do I get a touchUpInside event on the UINavigationItem or is there some other way I can do this?

Answer 1

So it turns out there's a very easy way of doing this:

• adding a UIBarButtonItem in the storyboard
• subclass the UITableViewController
• control-drag from the UIBarButtonItem to the UITableViewController subclass to create an action
• dismiss the UITableViewController in the action
