15. Creating the Edit Interface

Written by Sarah Reichelt

In the previous chapter, you created a contextual menu for the movies table. One of the menu items is for editing a movie, but at the moment, it doesn’t do anything.

Over the next two chapters, you’ll add and configure a new window for doing these edits, with edit fields for the data like the movie title and year, plus a table for listing and editing the movie principals.

When you finish, the edit window will look like this:

Adding a New Window

Launch Xcode and open your MovieTables project or get the starter project from the downloads for this chapter.

The first task is to add a new window controller and view controller in the storyboard. Open Main.storyboard and then open the Library using the + button in the bottom toolbar or by pressing Shift-Command-L.

Search for win and drag a Window Controller into any blank area in the storyboard. This adds a Window Controller with a window and a connected View Controller with a view.

Select the window and press Command-Option-5 to open the Attributes inspector. Set its Title to Edit. The window and view are too small, so switch to the next inspector along — the Size inspector — and set the Width to 600 and Height to 400. Press Tab or Return to process your new size, then check Minimum Content Size and make sure the same numbers appear there.

How do you decide what sizes to set? Looking at the design, the table is the widest component. It needs three columns, each of which will be between 150 and 200 pixels wide. Rounding that to a neat number gives a width of 600. For the height, you want to use a fraction of the width. Two-thirds of the width gives 400, which looks good. You may need to change this later as the design develops, but this provides a decent starting point.

Next, select the View Controller ▸ View and set its width and height to 600 and 400 to match.

This View Controller needs its own class. Press Command-N to open the new file template chooser. This time, choose macOS ▸ Source ▸ Cocoa Class. This gives a file containing a subclass of a known AppKit class.

Click Next and set the Class to EditViewController. Choose NSViewController from the Subclass of: popup. Uncheck Also create XIB file for user interface. You’ll use Main.storyboard for the design, so you don’t need a separate design file. Make sure Language is set to Swift and press Next, then Create:

This gives your project a new NSViewController class and now you can set it as the class for the newly added View Controller.

In Main.storyboard, select the new View Controller. Use the outline view to be sure you select the controller and not its view. Press Command-Option-4 to open the Identity inspector and use the Class popup to change it to EditViewController:

When you do this, the names in the outline view change too, making it easier to identify this view controller from now on.

Segueing to the New Window

The navigation link between two view controllers is a segue (pronounced SEG-way). To create a segue, position the objects in the storyboard so you can see the original View Controller and the new Edit window’s Window Controller. Click in the bar at the top of the View Controller so you can see its buttons. Control-drag from the View Controller icon into the new Edit Window Controller, not the Edit View Controller:

Preparing Data for the Edit Window

When you initiate a segue, it triggers a method called prepare(for:sender:). You can override this method to customize what happens during the transition. At this point, the segue knows where it’s heading, so this is a great place to set some properties on the destination.

The Editing Interface

The edit window has three main sections. The top section is for the single chunks of data: title, year etc. The middle is a table for the list of principals. And finally the bottom has the Cancel and Save Changes buttons.

Placing the Table View

Find Table View in the Library and drag it so it aligns with the left alignment guide and clicks into the standard spacing above the Cancel button:

Labeling the Edit Fields

The Principals label is set up the way you want, so select it and use Command-D or Option-Drag, whichever you prefer, to duplicate it. Drag the copy up to beside the top edit field. These field labels align to the left of their matching edit fields, so use the Attributes inspector to set the alignment to Right.

Saving the Edits

In order for EditViewController to call a method in ViewController, it needs access to that view controller.

Making Editing Easier

Before getting into the actual editing, there’s a feature you can add to the main table to make editing faster and easier. How about letting the user double-click a line to open the Edit window?

Key Points

• To show a secondary window, add a Window Controller and a View Controller to the storyboard.
• Use a segue to transition to the new window.
• Attach data to the segue to send it to the secondary window.

Where to Go From Here?

The next step is to show the data in the fields and table. You’ll also want to configure the fields for editing and set up the table for sorting and editing. That’s all in the next chapter.
