一般我们填充cell数据使用

 let cell = collectionView.mf_dequeueReusableCell(indexPath: indexPath) as MyConcernCell
cell.avatarImageView = UIImage(named:"")
cell.nameLabel.text = ""
return cell

如果cell属性过多会显得很乱，所以cell数据设置放到CellView中
首先在CellView中添加一个变量

import UIKit
import Kingfisher
class MyConcernCell: UICollectionViewCell,RegisterCellOrNib {
    //认证
    @IBOutlet weak var vipImageView: UIImageView!
    //用户头像
    @IBOutlet weak var avatarImageView: UIImageView!
    @IBOutlet weak var nameLabel: UILabel!
    //添加此属性用于接受Controller传来的数值
    var myConcern:MyConcern?{
        didSet{
            avatarImageView.kf.setImage(with: URL(string: (myConcern?.icon)!))
            nameLabel.text = myConcern?.name
            if let isVerify = myConcern?.is_verify{
                vipImageView.isHidden = !isVerify
            }
        
        }
    }
}

设置好之后我们只需要在ViewController中添加此代码即可

  cell.myConcern = myConcerns[indexPath.item]
