UIButton won't gray out

Question

Isn\'t UIButton supposed to become grayish/grayer when enabled=NO ?

I have a simple UIButton on a blackbackground (no custom images, no custom nothing, just dragged

I face the same problem because I had set background color.

I removed the background color and set it for UIControlStateNormal only and the default behaviour for enable/disable started to appear.

If you are setting background color instead of image try this category for converting UIColor to UIImage:

copied from here:

+ (UIImage *)imageWithColor:(UIColor *)color
{
    CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}

then use this:

[self.loginButton setBackgroundImage:[UIImage imageWithColor:greenColor] forState:UIControlStateNormal];
self.loginButton.enabled = NO;

to set the color as background. Now when you enable/disable, the gray effect should appear.
