Create animation for set of Images

 // The root view of the view controller set in Interface Builder is a UIImageView.

    UIImageView *imageView = (UIImageView *)self.view;

    

    imageView.animationImages = @[

                          [UIImage imageNamed:@"image_animal_1"],

                          [UIImage imageNamed:@"image_animal_2"],

                          [UIImage imageNamed:@"image_animal_4"],

                          [UIImage imageNamed:@"image_animal_5"]

                         ];

    

    // We want the image to be scaled to the correct aspect ratio within imageView's bounds.

    imageView.contentMode = UIViewContentModeScaleAspectFit;

    

    // If the image does not have the same aspect ratio as imageView's bounds, then imageView's backgroundColor will be applied to the "empty" space.

    imageView.backgroundColor = [UIColor whiteColor];

    

    imageView.animationDuration = 5;

    [imageView startAnimating];

    

    imageView.isAccessibilityElement = YES;

    imageView.accessibilityLabel = NSLocalizedString(@"Animated", nil);
