无法修改Array中的对象，也无法返回值（地图）

Question

我想更新数组中对象的值，然后设置状态

var array=this.state.filter_photos.map(x => {
  var container={}

  if(x.uri===this.state.photo_object.picture){
    x.new_uri=this.state.imageURI;
  }

  container=x;
  console.log('tableau30 ',container)

  return container;
});

console.log('tablau4',array) // can't read this 

this.setState({filter_photos :array}) //  can't setstate

**这是我的全部代码**

  

构造函数（道具）{           超级（道具）;

    this.state = {

      filter_photos: [],
}
    captureScreenFunction  ()  {

      this.refs.viewshot.capture().then(uri => {
        this.setState({ imageURI: uri }),
        CameraRoll.saveToCameraRoll(uri, "photo");
        this.state.photo_object.new_uri=this.state.imageURI;

        this.setState(prev => ({
          filter_photos: prev.filter_photos.map(photo => {
            if (photo.uri === prev.photo_object.picture) {
              photo.new_uri = prev.imageURI;
            }

            console.log('tableau30 ',photo)
            return photo;
          })
        }));
        console.log('tablau4',this.state.filter_photos) // this console doesn't show
      }); 
    }

render（）{

this.state.filter_photos = this.props.filter_photos; // initilisation 

return（）

****当我在控制台上显示this.state.filter_photos时，它不会显示* *我在渲染中启动了filter_photos ****
