To change the background color of a button in iOS application we need to access the property ‘ backgroundColor’ of the UIButton. We can do this in two ways, programmatically and using the storyboard.
Method 1 − Using the storyboard editor
Add a button on your storyboard, select it Go to it’s attribute inspector and select 'Background' property to choose the color.
Method 2 − Programmatically changing the background
Create outlet of the button on the View Controller.
In the viewDidLoad() or viewWillLayoutSubview() method add the code to change the background color.
btn.backgroundColor = #colorLiteral(red: 0.4392156899, green: 0.01176470611, blue: 0.1921568662, alpha: 1)
