Resizing a UIImageView programmatically

Question

I have tried several different solutions to this problem with no success.

I have a UIImageView (created on the Storyboard) that has multiple Gesture Recognizers on it. I have trying to resize this UIImageView based on screen size to take advantage of the 4 inch display.

It appears that since the Imageview was built using the storyboard, I can't change it programmatically???

My current code looks like this:

//determine screen size, set scoring button width based on device size.
CGFloat lCurrentHeight = self.view.bounds.size.height;
if (lCurrentHeight == 568.0) {
    CGRect _redHeadImageFrame = _redHeadImage.frame;
    _redHeadImageFrame.size.width = 220;
    [_redHeadImage setFrame:_redHeadImageFrame];
}

Any ideas??? Thanks.

If you are using autolayout you have to change withConstraint of the image, because manual changing of the frame will not work in this case.

EDIT

You can create IBOutlet for the width constraint as you do it for other controls - just select constraint in IB and move it with right button to your header file. Than in code change constraint:

[self.imageWidthConstraint setConstant:100.0];
