How to adjust an UIButton's imageSize?

Question

How can I adjust the image size of the UIButton? I am setting the image like this:

[myLikesButton setImage:[UIImage imageNamed:@\"icon-heart.png\"] forState:UICo         


        

Answer 1

Tim's answer is correct, however I wanted to add another suggestion, because in my case there was a simpler solution altogether.

I was looking to set the UIButton image insets because I didn't realize that I could set the content mode on the button's UIImageView, which would have prevented the need to use UIEdgeInsets and hard-coded values altogether. Simply access the underlying imageview on the button and set the content mode:

myButton.imageView.contentMode = UIViewContentModeScaleAspectFit;

See UIButton doesn't listen to content mode setting?

Swift 3

myButton.imageView?.contentMode = .scaleAspectFit
