width)) > (targetSize. height / image. size. height))) //scale to fit width, or scaleFactor = targetSize.
UIImageView* view = [[UIImageView alloc] initWithImage: [UIImage imageNamed: @"your_image.png"]];
view.frame = CGRectMake(0, 0, width, height);
To get the frame of the iPhone screen you can use
CGRect frame = [[UIScreen mainScreen] bounds];
In Interface Builder, select your UIImageView. From the Tools menu, select "Attribute Inspector". In the Image View Attributes palette, select "Scale to Fill" from the Mode popup. That should scale your image to fit.
