【iOS】使用xib自定义UITableViewCell

你可以使用xib，推荐使用，创建cell，同时创建Xib即可，xib上面可以自定义布局

// 注册nib
tableView.registerNib(UINib(nibName: "nibName", bundle: mainBundle), forCellReuseIdentifier: "cellIdentifier");
// 注册类
tableView.registerClass(TableViewCell.self, forCellReuseIdentifier: "cellIdentifier")

// 数据源
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        
        let cell = tableView.dequeueReusableCellWithIdentifier("cellIdentifier", forIndexPath: indexPath) as! TableViewCell
        return cell;
    }

使用注册类的时候需要手写代码
重写init(style: UITableViewCellStyle, reuseIdentifier: String?)方法，并在里面进行UI设置

1.自定义列

新建一个xib文件 carTblCell，拖放一个UITableViewCell,再拖放一个图片和一个文本框到tableviewcell上

并给我们的xib一个标识

为了学习，我这里的xib和后台的class是分开建的。我们再建一个cocoa touch class文件名称为CarCellTableViewCell继承自UITableViewCell

并把我们的xib和新建的CarCellTableViewCell建立联接

//  课程信息列表cell

import UIKit

class CourseViewCell: UITableViewCell {

    @IBOutlet weak var txtccredit: UILabel!
    @IBOutlet weak var txtcnum: UILabel!
    @IBOutlet weak var txtcname: UILabel!
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
    //  cell填充函数
    func loadData(name:String,num:String,credit:String){
        txtcname.text = name;
        txtcnum.text = num;
    
        txtccredit.text = credit;
    }

    
}

2.关联cell和tableview

1. 在main.storyboard上拖放一个uitableview，并在后台代码建立输出联接

1.在load事件里注册xib

2.在tableveiw的方法里得到当前的列，指定数据源。

    var tablelist=[String](repeating: "CourseName", count: 99)

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView!.register(UINib(nibName:"CourseViewCell", bundle:nil),
                                 forCellReuseIdentifier:"cell")
        
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

        return 1
    }
    //  列表行数
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return CourseItem().count
    }
    
    //  填充行
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell",for: indexPath)

        let credit0 = (CourseItem()[indexPath.row].value(forKey: "ccredit")as? String)!
        
        cell.loadData(name:name0 , num:num0, credit: credit0)
        
        tablelist[indexPath.row] = name0
