1.纯代码自定义UICollectionViewCell
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）
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
