Set alpha of background of UIButton but not the title

Question

When I set the alpha of the button it also affects the opacity of the title. Is there a way to target only the background and leave the title alpha at 1.0?

Answer 1

This works for me:

self.myButton.backgroundColor = [UIColor clearColor]; 

or if you don't want to have it completely clear, but still with transparency you can use:

self.myButton.backgroundColor = [UIColor colorWithRed:200.0/255.0 green:200.0/255.0 blue:200.0/255.0 alpha:0.5]; 

The second example would give you gray color with alpha 0.5.

SWIFT 4 Update

myButton.backgroundColor = .clear 

OR

myButton.backgroundColor = UIColor(red: 200.0/255.0, green: 200.0/255.0, blue: 200.0/255.0, alpha:0.5) 

Answer 2

You can also change the alpha of the color in the storyboard,
