发现会OC的 看swift还是比较简单的，只是不用分号很不习惯，仅此记录下学习时候写的简单代码
创建按钮
let button = UIButton(type: .custom)
button.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
view.addSubview(button)
button.backgroundColor = UIColor.blue
button .addTarget(self, action: #selector(click), for: .touchUpInside)
实现Button点击方法
func click() -> () {
}
创建imageView
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height))
imageView.backgroundColor = UIColor.red
imageView.image = UIImage(named: "timg.jpeg")
view .addSubview(imageView)
创建tableView
let tab = UITableView(frame:view.frame, style: .plain)
tab.delegate = self
tab.dataSource = self
view.addSubview(tab)
tab.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
//MARK: delegate
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView .dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = "\(indexPath.row)"
cell.selectionStyle = .none
cell.contentView.backgroundColor = UIColor.brown
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 44
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("\(indexPath.row)")
}
