ios - Swift中如何显示数组列表对应的图片

Question

在下面的代码中，我用图像文件名列表初始化了 Images 数组。我希望图像的顺序与 Names 数组的顺序对齐。这是我尝试过的，但我收到一条错误消息

Thread 1: EXC_BAD_INSTRUCTION ( code=EXC_I386_INVOP, subcode = 0x0)

The console output: fatal error: Array index out of range (lldb)

代码

 class NonameTableViewController: UITableViewController {


    var Names = [" Ferro", "Korean", "HUH?","CatCafe", "UINITY", "FAKESTORE" ,"IRANOUTOFNAMES", "OKAY", "KEEP CODING"]

    var Images = ["cafedeadend.jpg", "homei.jpg", "teakha.jpg", "cafelois1.jpg"," petiteoyster.jpg", "forkeerestaurant.jpg"]

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


        let cellIndentifier = "Cell"
        let cell = tableView.dequeueReusableCellWithIdentifier(cellIndentifier, forIndexPath: indexPath)


        //configure cell 

         cell.textLabel?.text = Names[indexPath.row]
        cell.imageView?.image = UIImage(named: Images[indexPath.row])

            return cell
} 


       override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
            // #warning Incomplete implementation, return the number of sections
            return 1
        }

        override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            // #warning Incomplete implementation, return the number of rows
            return Names.count
        }

Answer 1

只需更改您的numberOfRowsInSection 函数:

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return min(Names.count, Images.count)
}

这将确保您只显示您拥有名称和图像的图像的图像/名称。
