Recently, I am learning knowledge related to Animation. The book is called iOS Core Animation Advanced Techniques, and in Chinese it is called iOS Core Animation Advanced Techniques. I have read this book roughly, and it talks about low-level drawing, layers, 3D models and so on. I will update what I have learned every day. If there is any code, I will attach the Github address to witness the progress of my animation. The Chinese version of the book download address here, want to see friends download their own. pan.baidu.com/s/1bocdOGf If the link fails, please leave a message.
