You can add an image to the button using UIButton's setImage:forState: method and then you set the content sizing using UIView's contentMode property.

An example would look like this:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *img = [UIImage imageNamed:@"myImage.png"];

button.frame = CGRectMake(20, 100, img.size.width, img.size.height);

[button setImage:img forState:UIControlStateNormal];
[button setImage:img forState:UIControlStateHighlighted];
[button setImage:img forState:UIControlStateSelected];

button.contentMode = UIViewContentModeScaleToFill; //Look up UIViewContentMode in the documentation for other options

[self.view addSubview:button];
