做了这个小demo 之后 感觉OC 和swift 还是有很大的差别的 自己还是要去多看些swift的语法 用的不是很熟练
1.这个demo 的资源文件 我都是用原工程的
2.同样的自定义cell 的时候 用的是“SnapKit”这个库
3.其实这一个demo的主要就是自定义cell，思想和OC 是一样的 总感觉swift写的是那么的别扭，可能还是不熟悉语法吧，还是要多看多练
效果
代码 自定义cell 的代码
import UIKit
import SnapKit struct video {
let image: String
let title: String
let source: String } class VideoViewCell: UITableViewCell {
public var titleLabel:UILabel?
public var picImageView:UIImageView?
public var startImageView:UIImageView? override func awakeFromNib() {
super.awakeFromNib() } required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
} override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier);
self.setUpUI()
} func setUpUI() { self.picImageView = UIImageView.init()
self.addSubview(self.picImageView!) self.startImageView = UIImageView.init()
startImageView?.image = UIImage.init(named: "playBtn")
self.addSubview(self.startImageView!) self.titleLabel = UILabel.init()
self.titleLabel?.textColor = UIColor.white;
self.titleLabel?.textAlignment = .center
self.addSubview(self.titleLabel!) self.picImageView?.snp.makeConstraints { (make) in
make.top.equalTo(self).offset()
make.left.equalTo(self).offset()
make.width.equalTo(SCREEN_WIDTH)
make.height.equalTo(self)
} self.startImageView?.snp.makeConstraints({ (make) in
make.center.equalTo(self.snp.center)
make.width.equalTo()
make.height.equalTo()
}) self.titleLabel?.snp.makeConstraints({ (make) in
make.top.equalTo((self.startImageView?.snp.bottom)!).offset()
make.width.equalTo(SCREEN_WIDTH)
make.height.equalTo()
}) } override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated) // Configure the view for the selected state
} }
