Question

我正在研究的项目取决于UITableView。我在UIStoryboard内建了六个主要类别。我希望每个单元格与另一个UITableView相关联。

我使用segue代理，但它不起作用。我需要一个方法来委托UITableView文件：

class CategoriesView: UITableViewController {
    @IBOutlet weak var OthersCell: UITableViewCell!
    @IBOutlet weak var StoreCell: UITableViewCell!
    @IBOutlet weak var ArtAndDesigneCell: UITableViewCell!
    @IBOutlet weak var StudentServicesCell: UITableViewCell!
    @IBOutlet weak var BeautyCell: UITableViewCell!
    @IBOutlet weak var CheefsCell: UITableViewCell!
    override func viewDidLoad() {
        super.viewDidLoad()
        func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
            if (segue.identifier=="CheefsCelll") {let _=segue.destinationViewController as! CheefsView}
            else  if (segue.identifier=="BeautyCell") {let _=segue.destinationViewController as! BeautyView}
            else if (segue.identifier=="StudentServicesCell") {let _=segue.destinationViewController as! StudentServicesView}
            else  if (segue.identifier=="ArtAndDesigneCell") {let _=segue.destinationViewController as! ArtAndDesigneView}
            else  if (segue.identifier=="StoreCell") {let _=segue.destinationViewController as! StoreView}
            else  if (segue.identifier=="OthersCell") {let _=segue.destinationViewController as! OthersView}    
        }
        // 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 Incomplete implementation, return the number of sections
        return 0
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        return 6      
    }
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {  
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)  
        cell.accessoryType=UITableViewCellAccessoryType.DisclosureIndicator
        return cell
    }

Answer 1

首先，onLoad方法UITableViewDataSource必须返回一个不同于0的值。在您的情况下，它应该是1.

numberOfSectionsInTableView

如果这不起作用，请确保在IB或override func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 1 }中正确设置dataSource。

将表格单元格委托给其他tableview
