什么都没有出现在UITableView单元格中

Question

I am working on an app that needs to display five different images inside of five different tableview cells. This is the storyboard that I have for the cell.

This is the code I have inside of the tableviewcontroller.

    class MasterViewController: UITableViewController, UITableViewDelegate, UITableViewDataSource {
var returnTable = 1
var icons: [String] = ["settings", "calendar", "classes", "envelope", "grades"]




override func viewDidLoad() {
    super.viewDidLoad()






    // Uncomment the following line to preserve selection between presentations
    // self.clearsSelectionOnViewWillAppear = false

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 0
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete method implementation.
    // Return the number of rows in the section.


    return icons.count
}


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! HomeScreenCells


    var image : UIImage = UIImage(named: icons[indexPath.row])!
    cell.icon.image = image


    return cell
}

I also have a custom class for the tableviewcells. Also, I have the correct reuse identifier for the cell. Still, the image does not appear. Not only does the image not appear, nothing appears. When I change the background, the background does not change in the simulator. This is all I get in the simulator.

I have the classes linked up correctly for the split view controller. I have no idea why nothing is appearing in the table. Any help would be appreciated.

Answer 1

我认为您的问题可能是您将节数设置为0。或者将其设置为1，或者完全省略了代码块。

Answer 2

As stated above, return 1 in number of sections (or the number of cells you need). And if your custom cell class has a .xib, you also need to register it, sometimes after you init the tableview

tableView.registerNib( UINib(nibName: "HomeScreenCells", bundle: nil), forCellReuseIdentifier: "Cell")
