How can I alter the height of a UIView using CGAffineTransformScale?

Is it possible to change the height of a UIView alone using CGAffineTransformScale?

I do not want to entirely scale my UIView. I just wanted to increase the height alone?

You may not use transform. Better to set the frame of the UIView. Since this really change the height of the view.

view.frame=CGRectMake(0,0,100,200);

Something like this:

view.transform = CGAffineTransformMakeScale(1.0, 2.0);

Will make your view twice as high but the same width. However, transforms are applied after rasterisation so you'll just get the original pixels stretched out, you won't reveal any extra detail. You should also be aware, from the UIView documentation, that if transform is set to anything other than the identity then frame becomes undefined.
