用swift实现tableview的展示
import UIKit
class ViewController:UIViewController,UITableViewDelegate,UITableViewDataSource {
var baby = ["测试0","测试1","测试2","测试3","测试4","测试5","测试6","测试7","测试8","测试9","测试10","测试11"]
var tableView = UITableView()
var isFlag = [Bool](count :12, repeatedValue: false)
override func viewDidLoad() {
super.viewDidLoad()
tableView = UITableView(frame: CGRectMake(0,0, 320, 600), style: UITableViewStyle.Plain)
tableView.dataSource =self
tableView.delegate =self
self.view.addSubview(tableView)
}
func numberOfSectionsInTableView(tableView:UITableView) -> Int {
return 1
}
//每一块有多少行
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) ->Int {
return baby.count
}
//绘制cell
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let initIdentifier = "Cell"
let cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: initIdentifier)
//下面两个属性对应subtitle
cell.textLabel?.text =baby[indexPath.row]
cell.detailTextLabel?.text ="测试\(indexPath.row)"
cell.imageView!.layer.cornerRadius =40
cell.imageView!.layer.masksToBounds =true
//添加附件
cell.accessoryType =UITableViewCellAccessoryType.DetailButton
if isFlag[indexPath.row] {
cell.accessoryType =UITableViewCellAccessoryType.Checkmark
}else{
cell.accessoryType =UITableViewCellAccessoryType.None
}
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
//使用闭包，和嵌套函数或者JAVA中的匿名类类似
let locationActionHandler = {(action: UIAlertAction!) -> Void in

//每个cell的高度
