今天看到的代码，动画效果不错，代码也比较简单，只有想不到，没有做不到。😁😁😁😁😁😁😁

代码也很简单：
[self.iconImageView sd_setImageWithPreviousCachedImageWithURL:model.pictureUrl
placeholderImage:nil
options:0
progress:nil
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
if (cacheType == SDImageCacheTypeNone) {
wself.iconImageView.image = image;
wself.iconImageView.alpha = 0;
wself.iconImageView.scale = 1.25f;
[UIView animateWithDuration:0.35 animations:^{
wself.iconImageView.alpha = 1.f;
wself.iconImageView.scale = 1.f;
}];
}
}];
