How do you create a semi-transparent background for a UIView?

Question

I am creating a UIView containing some text that partially covers a UIImageView. I want the user to be able to read the text and still maintain a perspective on the image undern

Answer 1

Swift 3+

white half transparent:

view.backgroundColor = UIColor(white: 1, alpha: 0.5)

or black half transparent:

        view.backgroundColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.5)

Answer 2

I think what you mean is you want the backgroundColor of your UIView to be semi transparent? If you want white/transparent use this:

myView.backgroundColor = [UIColor colorWithWhite:myWhiteFloat alpha:myAlphaFloat];

else if you want it to be another color use the general UIColor method: +colorWithRed:green:blue:alpha:
