Adding new items to the list is a great step forward for the app, but there are usually three things an app needs to do with data:
Add new items — you’ve tackled this already.
Deleting items — you allow that with swipe-to-delete.
Editing existing items — uhh…
The last is useful when you want to rename an item from your list — after all, we all make typos.
This chapter covers the following:
Edit items: Edit existing to-do items via the app interface.
Refactor the code: Using Xcode’s built-in refactoring capability to rename code to be easily identifiable.
One more thing: Fix missed code changes after the code refactoring using the Find navigator.
Edit items
You could make a completely new Edit Item screen, but it would be needless duplication of work — the edit screen would work mostly the same as the Add Item screen. The only difference is that it doesn’t start out empty — instead, it works with an existing to-do item.
So, let’s re-use the Add Item screen and make it capable of editing an existing ChecklistItem object.
Editing a to-do item
For the edit option, when the user presses Done, you won’t have to make a new ChecklistItem object, instead, you will simply update the text in the existing ChecklistItem.
You’ll also tell the delegate about these changes so that it can update the text label of the corresponding table view cell.
Exercise: What changes would you need to make to the Add Item screen to enable it to edit existing items?
Answer:
The screen title must be changed to Edit Item.
You must be able to pass it an existing ChecklistItem object.
You have to place the ChecklistItem’s text into the text field.
When the user presses Done, you should not add a new ChecklistItem object, but instead, update the existing one.
There is a bit of a user interface problem, though… How will the user actually open the Edit Item screen? In many apps that is done by tapping on the item’s row, but in Checklists that already toggles the checkmark on or off.
To solve this problem, you’ll have to revise the UI a little first.
Revise the UI to allow editing
When a row is given two functions, the standard approach is to use a detail disclosure button for the secondary task:

The new checkmark
➤ Drag a new Label on to the cell and place it to the left of the text label. Give it the following attributes:

The edit screen segue
Next, you’re going to make the detail disclosure button open the Add/Edit Item screen. This is pretty simple because Interface Builder also allows you to make a segue for a disclosure button.

We’ve talked about screen B (the Add/Edit Item screen) passing data back to screen A (the Checklists screen) via delegates. But here, you’re passing a piece of data the other way around – from screen A to screen B – namely, the ChecklistItem to edit.

Iterative development
If you think this approach to development we’ve taken so far is a little messy, then you’re absolutely right.
