Learn iOS and ios

Learn iOS and ios

After doing this demo, I feel that OC and swift are quite different. I still want to read more about swift syntax, but I am not very skilled.

1. I used the original project for the resource files of this demo.

2. The "SnapKit" library is used for the same custom cell.

3. In fact, this demo mainly involves custom cells. The idea is the same as that of OC. I always feel that swift is so awkward to write. Maybe I am not familiar with the syntax. I still need to read more and practice more.

Code custom cell Code

import UIKitimport SnapKitstruct 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(0)            make.left.equalTo(self).offset(0)            make.width.equalTo(SCREEN_WIDTH)            make.height.equalTo(self)        }                self.startImageView?.snp.makeConstraints({ (make) in            make.center.equalTo(self.snp.center)            make.width.equalTo(100)            make.height.equalTo(100)        })                self.titleLabel?.snp.makeConstraints({ (make) in            make.top.equalTo((self.startImageView?.snp.bottom)!).offset(20)            make.width.equalTo(SCREEN_WIDTH)            make.height.equalTo(20)        })                            }        override func setSelected(_ selected: Bool, animated: Bool) {        super.setSelected(selected, animated: animated)        // Configure the view for the selected state    }}
