Swift 实现简单自定义TableViewCell

自定义cell其实还是比较简单的，个人理解，直接把自己需要的控件添加为子视图就行了。

下面直接给出简单代码块：

TableViewCell.swift代码块如下：

class TableViewCell: UITableViewCell {    var title:UILabel!    var clickBtn:UIButton!    override func awakeFromNib() {        super.awakeFromNib()    }        override init(style: UITableViewCellStyle, reuseIdentifier: String?) {        super.init(style: style, reuseIdentifier: reuseIdentifier)        if !self.isEqual(nil) {            title = UILabel(frame: CGRectMake(20, 20, 200, 30))            self.contentView.addSubview(title)            clickBtn = UIButton(frame: CGRectMake(200, 20, 60, 30))            clickBtn.setTitle("app", forState: UIControlState.Normal)            clickBtn.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)            clickBtn.setTitleColor(UIColor.whiteColor(), forState: UIControlState.Highlighted)            self.contentView.addSubview(clickBtn)        }    }    required init(coder aDecoder: NSCoder) {        fatalError("init(coder:) has not been implemented")    }    override func setSelected(selected: Bool, animated: Bool) {        super.setSelected(selected, animated: animated)    }}

ViewController.swift代码块如下：

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {        var table:UITableView!    var array = ["item1","item2","item3","item4","item5","item6","item7"]    override func viewDidLoad() {        super.viewDidLoad()        title = "FirstApp"        var view: UIView = UIView(frame: self.view.frame)        view.backgroundColor = UIColor.whiteColor()        self.view.addSubview(view)                var leftButton:UIBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Edit, target: self, action:"leftCall:")                self.navigationItem.leftBarButtonItem = leftButton                var rightButton:UIBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Add, target: self, action: "rightCall:")                self.navigationItem.rightBarButtonItem = rightButton                var rect  = self.view.frame        rect.origin.y += 65        table = UITableView(frame: rect)        table.registerClass(TableViewCell.self, forCellReuseIdentifier: "cell")                self.view.addSubview(table)                table.delegate = self        table.dataSource = self    }    func numberOfSectionsInTableView(tableView: UITableView) -> Int {        return 1    }        func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {        return 60    }        func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {        return array.count    }        func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        var str:String = "cell"                var cell:TableViewCell = tableView.dequeueReusableCellWithIdentifier(str, forIndexPath: indexPath) as TableViewCell                if cell.isEqual(nil) {            cell = TableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: str)        }        cell.title.text = array[indexPath.row]                cell.clickBtn.tag = indexPath.row        cell.clickBtn.removeTarget(self, action: "tableViewCellClicked:", forControlEvents: UIControlEvents.TouchUpInside)        cell.clickBtn.addTarget(self, action: "tableViewCellClicked:", forControlEvents: UIControlEvents.TouchUpInside)                return cell    }    func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {        if editingStyle == UITableViewCellEditingStyle.Delete  {            array.removeAtIndex(indexPath.row)            table.reloadData()        }    }        func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {        println("clicked at \(indexPath.row)")    }        override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }        func leftCall(sender:AnyObject) {        table.setEditing(!table.editing, animated: true)        var btn:UIBarButtonItem = sender as UIBarButtonItem        btn.title = "Done"        println("leftButton pressed")    }    func rightCall(sender:AnyObject) {        array.append("新建cell")        table.reloadData()        println("rightButton pressed")    }    func tableViewCellClicked(sender:AnyObject) {        println("tableViewCell appButton at \((sender as UIButton).tag) clicked")    }}

以上便是swift中自定义TableViewCell的简单实现，第一次写blog，有错得地方希望大神指教，当然实现自定义TableViewCell的方式不止这一种。
