UITextField: change appearance for disabled textfields

Question

I'd like to change the appearance of disabled textfields, i.e. text and background color - is there an easy and legal way to achieve this?

Answer 1

You could subclass your UITextfield and overwrite the enabled property like this

- (void)setEnabled:(BOOL)enabled
{
    [super setEnabled:enabled];
    // Do your customization here, eg:
    self.backgroundColor = [UIColor blackColor];
}

Swift version:

override var isEnabled: Bool {
    willSet {
        backgroundColor = newValue ? UIColor.white : UIColor.black
    }
}
