scale Image in an UIButton to AspectFit?

Question

I want to add an image to a UIButton, and also want to scale my image to fit with the UIButton (make image smaller). Please show me how to do it.

This is what I have tried, but it does't work:

• Adding image to button and using setContentMode:

[self.itemImageButton setImage:stretchImage forState:UIControlStateNormal];
[self.itemImageButton setContentMode:UIViewContentModeScaleAspectFit];

• Making a "stretch image":

UIImage *stretchImage = [updatedItem.thumbnail stretchableImageWithLeftCapWidth:0 topCapHeight:0];

Answer 1

I had the same problem. Just set the ContentMode of the ImageView that is inside the UIButton.

[[self.itemImageButton imageView] setContentMode: UIViewContentModeScaleAspectFit];
[self.itemImageButton setImage:[UIImage imageNamed:stretchImage] forState:UIControlStateNormal];

Hope this helps.

Answer 2

None of the answers here really worked for me, I solved the problem with the following code:

button.contentMode = UIViewContentModeScaleToFill;
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentFill;
button.contentVerticalAlignment = UIControlContentVerticalAlignmentFill;

You can do this in the Interface Builder as well.
