继承UITableViewDataSource必须实现的方法

有两个方法必须实现，一个是cellForRowAtIndexPath（设定cell内容），还有一个是numberOfRowsInSection（设定行数）。

1、设定行数

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 7
    }

 2、设定cell中内容

  //创建单元格（函数名和参数的写法是固定的）

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let row = indexPath.row

        //定义的是reuseIdentifier: reuserIdentifier中的后一个,是cell的标识

        let reuserIdentifier = "Cell"

        let cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: reuserIdentifier)

        

        

        switch row{

        case 0:

            //lineView1是在cell0上方加的一个间隔区

            let lineView1=UIView(frame: CGRectMake(0,0,ScreenSize.SCREEN_WIDTH,10))

            lineView1.backgroundColor=UIColorFromRGB(244, green: 244, blue: 244, alpha: 1.0)

            cell.addSubview(lineView1)

            

            let str = NSMutableAttributedString(string: "*联系人")

            //设定cell中文字的颜色

            cell.textLabel?.textColor=textColor

            //str中的首字符的颜色单独设定

            str.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range: NSMakeRange(0, 1))

            cell.textLabel?.attributedText = str

            

            //在该cell中添加的输入框

            let textF = UITextField(frame: CGRectMake(130,12,ScreenSize.SCREEN_WIDTH-70,42))

            //为了保存输入的内容

            textF.tag=10

            textF.delegate = self

            

            //文本定义

//            textF.text = "emergency" //紧急联络人

            

            let str0 = NSMutableAttributedString(string:"输入联系人")

            str0.addAttribute(NSForegroundColorAttributeName, value: placeholderColor, range: NSMakeRange(0, str0.length))

            //Placeholder占位符定义，占位符在点击输入时，原内容自动消失

            textF.attributedPlaceholder = str0

            textF.font = UIFont.systemFontOfSize(14)

            textF.backgroundColor=UIColor.whiteColor()

            textF.delegate=self

            cell.addSubview(textF)

            

        case 1:

            let str = NSMutableAttributedString(string: "*Tel")

            cell.textLabel?.textColor=textColor

            str.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range: NSMakeRange(0, 1))

            cell.textLabel?.attributedText = str

            let textF = UITextField(frame: CGRectMake(130,2,ScreenSize.SCREEN_WIDTH-70,42))

            textF.tag=11

            textF.font = UIFont.systemFontOfSize(14)

            if duedate != ""{
