How do you change UIButton image alpha on disabled state?

Question

I have a UIButton with an image and on its disabled state, this image should have .3 alpha.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
UIIm         


        

Answer 1

The button’s image view. (read-only)

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

Although this property is read-only, its own properties are read/write.
