Does SwiftUI have customization options?
SwiftUI doesn’t provide us too many customization options on a menu. But still, it gives us the MenuStyle protocol that we can use to create our appearances. It works similarly to all style protocols that we have in SwiftUI. We can set it via the environment to share the styling with the view hierarchy.
Use Case
Dropdown menus should be employed sparingly and reserved for situations when you want your user to select from a fairly limited range of options. Visually the screen real estate that the UI occupies is comparable to a textfield, so you can imagine using it in a ViewController that is busy with several other UI elements.
DropdownTextField: Overview
The logic involved with our dropdown is not so complex, but there is a lot of interplay between the different views, some of which are animated or hidden at different times. To get an appreciation of what we are building and how the parts work together, let’s examine the diagram below:
Step 1: Create Subview Hierarchy
As we have already seen, there is a lot of initial setup of views that needs to happen. To assist with the process, let’s take a quick look at some helpful extensions. First we have a Theme enum that we put in an extension of UIImage.
Step 2: Create and Assign Delegate
The good news is that the subviews appear to be where we want them, and our big chunk of setup code has now been taken care of. Our goal now is to create a delegate so that our ViewController can receive information from the dropDown.
Step 3: Add Options to TableView
Our next step is to get our options to appear in the tableView. First we need our custom DropDownCell subclassing UITableViewCell. There’s very little required here. We add lightColor and cellFont properties to ensure that the cell is styled consistently with the colours and font of our DropDownTextField.
Step 4: Add Animation and Option Selection
With our options displaying correctly in our tableview, we can now turn our attention to animating the appearance of our menu and handling option selection. Our animationView and tableView are both hidden upon initialization, so we can uncomment the isHidden lines from Step 1. We next implement the method menuAnimate (up:) (lines 9–24).
Step 5: Add TextField Logic
At the moment, if the user taps on the last cell in the menu marked “Other”, nothing happens. Let’s fix that. Upon selection, we want to animate the menu up and handle the user typing their own option into the textField. First we need to uncomment the assignment of self as the textfield delegate which we saw in step one.
