Solved: How to change the backgroundColor of UIDatePicker or UIPicker ?

Understanding the overall theme and visual appeal of an application is largely contingent on the aesthetic elements it incorporates; user interface and user experience. One aspect of this is customizing background colors of elements to enhance the aesthetic appeal. In the instance of a UIDatePicker or a UIPickerView, customizing the background color can provide a better user experience. Swift language provides several ways to achieve this. This article will guide you on how to do so.

Let’s dive into the solution.

let myDatePicker = UIDatePicker()
myDatePicker.backgroundColor = UIColor.cyan

let myPickerView = UIPickerView()
myPickerView.backgroundColor = UIColor.cyan

The solution leans into the properties of Swift’s UIDatePicker and UIPickerView objects. In Swift, backgroundColor is a property of UIView, and since UIPickerViews and UIDatePickers are subclasses of UIViews, they inherit this property.

Step-by-step explanation of the code

1. Initialize the UIDatePicker or UIPickerView.

let myDatePicker = UIDatePicker()
let myPickerView = UIPickerView()

This instantiates a UIDatePicker and a UIPickerView.

2. Use the backgroundColor property to change the background color.

myDatePicker.backgroundColor = UIColor.cyan
myPickerView.backgroundColor = UIColor.cyan

The UIColor class, as the name suggests, offers a variety of ways to define colors.

Understanding UIView background properties in Swift

The UIView class in Swift provides visual elements that form the core of any user interface. Included in these visual elements are UI controls such as buttons, text fields, and, in our case, date pickers and normal picker views.

One of the most versatile properties of UIViews is the availability to change the background color. It offers a neat method to blend views into the overall aesthetic of the application with a single line of code. The backgroundColor property specifically changes the background color of the UIView, which in-turn reflects on the user interface of an application.

A UIView, including its classes and subclasses, has many manipulative attributes. The backgroundColor property is inherited from the UIView superclass which provides us the ability to change the background color as desired.

Considerations of UIColor in Swift

UIColor in Swift is a powerful class. It is used to represent colors in terms of red, green, and blue (RGB) values, hue, saturation, brightness, and alpha values, white and alpha values, or using a patterned image. We can set predefined or system colors.

With the provided properties, you can modify the background color of UIDatePicker or UIPickerView to match the theme of your application, hence creating a cohesive and visually appealing application.

Remember, a good user experience design always matters. Your application’s design can follow the principle of aesthetic integrity whereby the appearance of app elements help users understand how to interact with content and features.
