tableView.delegate = self
tableView.register(UserCell.self, forCellReuseIdentifier: "UserCell")
view.addSubview(tableView)
// 设置表格视图的布局
tableView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
tableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
])
}
}
extension UserManagementViewController: UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// 返回用户数量
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "UserCell", for: indexPath) as! UserCell
// 设置单元格内容
cell.usernameLabel.text = "用户名(indexPath.row)"
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// 跳转到用户详情页面
}
}
四、性能优化
1. 使用懒加载【16】技术，避免一次性加载过多数据。
2. 使用缓存机制【17】，减少网络请求次数。
3. 使用异步加载【18】图片，避免阻塞主线程。
4. 使用分页加载【19】，提高用户体验。
五、总结
本文以Swift语言为基础，实现了旅游酒店预订功能。通过分析需求、技术选型和功能实现，展示了如何使用Swift语言开发一款实用的旅游酒店预订应用。在实际开发过程中，还需不断优化性能，提高用户体验。希望本文对您有所帮助。
