iOS APP/SWIFT #3 (4–1) using iOS SDK to make a beautiful card

Load an iron man image with 1000 x 1000 pixels

using .contentMode : scaleAspecFit at Frame change to 1000x2000 pixels

using .contentMode : scaleToFill at Frame change to 1000x2000 pixels

using .contentMode : scaleAspecFill at Frame change to 1000x2000 pixels

And then add the text label, set the front size, color, background color.

Using CGAffineTransform to rotated iron man image and then add iron man and messageLabel to a subView of spaceImage

using loop function to add stars around the spaceImage
