ios - Disabled UIButton not faded or grey

In my iPhone app, I have a UIButton which I have created in Interface Builder. I can successfully enable and disable it like this in my code ...

sendButton.enabled = YES;

or

sendButton.enabled = NO;

However, the visual look of the button is always the same! It is not faded or grey. If I attempt to click it though, it is enabled or disabled as expected. Am I missing something? Shouldn't it look faded or grey?

You can use following code:

sendButton.enabled = YES;
sendButton.alpha = 1.0;

or

sendButton.enabled = NO;
sendButton.alpha = 0.5;
