Not a problem. If you want to adjust image view height and width according to view so use some thing like this,

float height=yourView.height;
float width=yourView.Width;

CGRect imageFrame=yourImageView.view.frame;

//set these values according to you
imageFrame.size.height=height-50;
imageFrame.size.width=width-50;

imageFrame.origin.x=20;
imageFrame.origin.y=40;

yourImageView.view.frame=imageFrame;
