本文介绍了使用Core Animation实现视图动画与过渡效果的方法，包括CATransition类的应用及UIView动画属性的配置。

CATransition *animation = [CATransition animation];
animation.duration = 0.5;
animation.type = kCATransitionMoveIn;
animation.subtype = kCATransitionFromRight;
[myImageView.layer addAnimation:animation forKey:@"imageTransition"];
myImageView.image = newImage;

        /////1
//        [UIView
//         animateWithDuration:duration
//         delay:delay
//         options:(UIViewAnimationCurve)opt
//         animations:^{
//             self.image47.alpha = 0;
//             self.imageView472.alpha = 1;
//         }
//         completion:^(BOOL finished){
//             self.image47.hidden = YES;
//         }
//         ];
            ////2
        [UIView transitionFromView:self.image47
                            toView:self.imageView472
                          duration:duration
                           options:UIViewAnimationOptionTransitionCrossDissolve
                        completion:^(BOOL finished) {
                            // animation completed
                        }];
