Based on a number of thread, i've aggregated an answer into a category on UIActionSheet, adding a setButton:toState method as follows. Hope it helps:

@interface UIActionSheet(ButtonState)
- (void)setButton:(NSInteger)buttonIndex toState:(BOOL)enbaled;
@end

@implementation UIActionSheet(ButtonState)
- (void)setButton:(NSInteger)buttonIndex toState:(BOOL)enabled {
    for (UIView* view in self.subviews)
    {
        if ([view isKindOfClass:[UIButton class]])
        {
            if (buttonIndex == 0) {
                if ([view respondsToSelector:@selector(setEnabled:)])
                {
                    UIButton* button = (UIButton*)view;
                    button.enabled = enabled;
                }
            }
            buttonIndex--;
        }
    }
}
@end
