Question

为什么UItableView需要数据源？？？？

Answer 1

The data source is a delegate. It tells you that I put my basket here (corresponding proxy method). You only need to put what you want to display here, and I will display it for you. You don’t need to do anything else. worry.
This separates the view and the model.
