UIButton imageView example in Objective C (iOS).

UIButton imageView

The button’s image view. (read-only)

@property(nonatomic, readonly, retain) UIImageView *imageView

Discussion of [UIButton imageView]
Although this property is read-only, its own properties are read/write. Use these properties to configure the appearance and behavior of the button’s view. For example:

UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect];
button.imageView.exclusiveTouch = YES;
The imageView property returns a value even if the button has not been displayed yet. The value of the property is nil for system buttons.

    return toReturn;
}
