.scaleAspectFit - filling the blanks with black color

Question

I have UIImages that I show in a UIImageView. The UIImageView has the

contentMode = .scaleAspectFit

property. The UIImages show just fine on the UIImageView, but I want to edit the UIImages so that they don't have any blank (transparent) space, and instead fill the blank spaces with a black color, and I want it to do this dynamically, depending on the end-users screen size.

Example:

What I want to do is replace the areas I've drawn in, with a black color, and save it as an UIImage.

Answer 1

Simply set backgroundcolor for the uiimageview

Answer 2

Set the background Color of the imageView to black

Using imageView outlet

self.imageView.backgroundColor = UIColor.black

Using IB

Answer 3

Set black color for imageview as well as set frame equal to frame of main view.

self.imageView.backgroundColor = UIColor.black

For AutoRisize:

self.imageView.frame = self.view.frame

For AutoLayout:
Set leading, trailing, top and bottom constraints with main view (self.view)
