pop动画库简单使用小记

- (void)animateInView:(UIView *)view{
    UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"auto_common_点赞高亮"]];
    imageView.frame = view.frame;
    imageView.contentMode = UIViewContentModeScaleAspectFit;
    [self addSubview:imageView];

    view.hidden = YES;

    POPBasicAnimation *animation = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerSize];
    animation.duration = 0.2;
    [animation setCompletionBlock:^(POPAnimation *anim, BOOL finish) {
        if (finish) {
            POPBasicAnimation *animation = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerSize];
            animation.duration = 0.1;
            [animation setCompletionBlock:^(POPAnimation *anim, BOOL finish) {
                if (finish) {
                    [imageView removeFromSuperview];
                    view.hidden = NO;
                }
            }];
            animation.toValue = [NSValue valueWithCGSize:view.lh_size];
            [imageView pop_addAnimation:animation forKey:@"size"];
        }
    }];
    animation.toValue = [NSValue valueWithCGSize:CGSizeMake(40, 40)];
    [imageView pop_addAnimation:animation forKey:@"size"];
}
