1.纯代码自定义UICollectionViewCell

swift">import UIKit

class NewDeviceBottomCollectionViewCell: UICollectionViewCell {
    
    var model:NewBottomModel = NewBottomModel(image: "海拔", text: "test") {
        didSet{
            reloadData()
        }
    }
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupUI()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    var bottomLabel = UILabel()
    var topImageView = UIImageView()
    
    func setupUI(){
        contentView.backgroundColor = newUIBlack
        contentView.addSubview(topImageView)
        topImageView.snp.makeConstraints { make in
            make.top.equalToSuperview().offset(10)
            make.width.height.equalTo(25)
            make.centerX.equalToSuperview()
        }
        
        contentView.addSubview(bottomLabel)
        bottomLabel.textColor = .white
        bottomLabel.snp.makeConstraints { make in
            make.centerX.equalToSuperview()
            make.top.equalTo(topImageView.snp_bottom).offset(10)
            
        }
        
    }
    
    func reloadData(){
        bottomLabel.text = "平均速度"
        topImageView.image = UIImage(named: model.image)
    }
}

2.禁止滑动（弹簧效果）

swift">        collectionView.bounces = false

参考博客：
iOS swift-UIScrollview，UITableview，UICollectionView单独禁止下拉（上拉）

3.UICollectionView的长按拖动

2.在一个控制器中放两个UICollectionView或者UITableView,代理方法要怎么写
