Using UIView animateWithDuration: delay: Xcode

Question

I'm trying to use

[UIView animateWithDuration:1 delay:2 options:UIViewAnimationOptionCurveEaseIn animations:^{
} completion:^ (BOOL completed) {}         ];

however no matter what number I put for the delay, there is no delay.
I'm trying to make a series of buttons fade out one after another when another button is touched. Therefore, I use a series of UIView animations with different delay times, but they all appear at the same time, no matter what time delay I enter. Does anyone have any suggestions?

        //Leave it empty
                 }
                 completion:^(BOOL finished){

// Your code goes here

Use function like this & set your UI Element properties like this:
 [UIView animateWithDuration:0.6
                          delay:0.3
                        options: UIViewAnimationOptionCurveEaseInOut
                     animations:^{
                         [self.view layoutIfNeeded];
                         [yourviews setTintColor:[UIColor whiteColor]];
                         self.view.backgroundColor = [UIColor greenColor];
                     }
                     completion:^(BOOL finished){

                         // You next action to perform after completion;
                     }];
}
