如何使用Swift在UITableview中加载自定义单元格(Xib) [英] How to load Custom cell (Xib) in UITableview using Swift

问题描述

这是我的代码

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int 
{
    return 10   
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
    var cell :UITableViewCell = tableView.dequeueReusableCellWithIdentifier("discovered") as UITableViewCell!

    bluetoothlog.registerNib(UINib(nibName: "devicedet", bundle: nil), forCellReuseIdentifier: "discovered")
    //NSBundle.mainBundle().loadNibNamed("devicedet", owner: nil, options: nil)[0] as UITableViewCell

    cell = blucell
    devname.text = peri[indexPath.row]
    devstrength.text = signalstrength[indexPath.row]

    bluetoothlog.backgroundColor = UIColor.clearColor()
    return cell        
}

我已尝试使用上述代码，但Tableview中未显示任何内容，请帮助我更改此代码的工作方式

I have tried with the above code and nothing is displayed in Tableview, please help me to change this code working

推荐答案

import UIKit
    class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    //MARK:- Sample Data Array to load in TableView
        let sampleArrray: \[String\] = \["val1", "val2", "val3", "val4", "val5"]

    //MARK:- Cell reuse identifier 
        let cellReuseIdentifier = "cell"


    //MARK:- UITableView outlet 
         @IBOutlet var tableView: UITableView!

          override func viewDidLoad() {
            super.viewDidLoad()

            // Registering the custom cell

            self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)

            // Setting delegate and Datasourse as same viewcontroller (this code is not neccessory if we are setting it from storyboard)

            tableView.delegate = self
            tableView.dataSource = self
        }
    //UITableview required methods 

        func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return sampleArrray.count
        }

        func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
            let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellReuseIdentifier) as UITableViewCell!

            cell.textLabel?.text = sampleArrray\[indexPath.row\]

            return cell
        }

        func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
           print("clicked at: \(indexPath.row)")
           //Here u can get the selected cell and add action related to this cell seelction 
        }
