UITableViewController 中的 customCell UITextField 在运行时不显示 swift

Question

我在我的项目中遇到了一个奇怪的问题。我的 UITextField、UILabel 和 UIButton 在运行时没有出现，即使所有引用插座都被正确提及

这是我的 tableview 控制器代码：

class ComposeMessageTableViewController:  UITableViewController, UITableViewDelegate, UITableViewDataSource {


@IBOutlet var composeMessage: UITableView!

let composeCellArray = ["composeMessage"]
override func viewDidLoad() {
    super.viewDidLoad()
    composeMessage.delegate = self
    composeMessage.dataSource = self
    composeMessage.separatorStyle = .None
    composeMessage.backgroundColor = UIColor.whiteColor()

}

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 {
    // Return the number of rows in the section.
    return composeCellArray.count
}
 override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let composeCell = tableView.dequeueReusableCellWithIdentifier(composeCellArray[indexPath.row]) as! ComposeMessageCell
    if(indexPath.row == 0){
 //        composeCell.toLabel.text = composeCellArray[indexPath.row] as String
//        composeCell.recepientTextField?.text = composeCellArray[indexPath.row] as String
    composeCell.toLabel.text = "To"
    composeCell.recepientTextField?.placeholder = "Recepients"
    composeCell.addButton.tag=indexPath.row
    composeCell.addButton.addTarget(self, action: "addMembers:", forControlEvents: UIControlEvents.TouchUpInside)
    }
    // Configure the cell...
    composeCell.backgroundColor = UIColor.clearColor()
    composeCell.selectionStyle = .None

    return composeCell


}
@IBAction func addMembers(sender:UIButton){

}

@IBAction func dismissnav(sender: AnyObject) {
    dismissViewControllerAnimated(true, completion: nil)
}

}

这里是 tableviewcell 代码：

class ComposeMessageCell: UITableViewCell {

@IBOutlet var toLabel: UILabel!
@IBOutlet var recepientTextField: UITextField!
@IBOutlet var addButton: UIButton!

override func awakeFromNib() {
    super.awakeFromNib()

    toLabel.font = UIFont(name: "Avenir-Black", size: 16)
    toLabel.textColor = UIColor.blackColor()
}

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

    // Configure the view for the selected state
}
}

请告诉我哪里错了

Answer 1

以下委托应return1

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1
}

Answer 2

正如@Prabhu 提到的方法委托：

 override func numberOfSectionsInTableView(tableView: UITableView) -> Int {

    return 1
}

应该始终 return 1，这是默认值或您设置的其他值。
