Share the Love icon lottie
初试lottie动效，确实非常强大，尤其对资源的节省程度。但AE有很多特效不支持，不单如此，导出的lottie文件对各平台的兼容也不是很全面，AE的图层alpha遮罩在iOS下是不支持的。
The initial trial of lottie is really powerful, especially with regard to resource savings. However, AE has many special effects that are not supported. Not only that, the exported lottie files are not very comprehensive for each platform. AE's layer alpha mask is not supported under iOS.
