Warning: An update (setState, replaceState, or forceUpdate) was scheduled from inside an update function. Update functions should be pure, with zero side-effects. Consider using componentDidUpdate or a callback.

问题出在你在用this.setState的callback的方式，但是在callback里你由调用了setState, 比如：

this.setState((prevState) => {
  // ...
  this.setState({ a: aaa })
})

所以应该返回新的state:

this.setState((prevState) => {
  // ...
  return { a: aaa }
})
