iOS - UIVIewController中的UITableView不显示所有行[Swift](iOS - UITableView in UIVIewController doesn't display all rows [Swift])

 我在UIViewController遇到了我的UITableView的错误。 我会试着解释一下情况和问题。 
 
 我有一个TabBarController ，其视图是带有UITableView的UIViewController 。 我没有使用UITableViewController因为我的UIViewController上有一些特定的控件。 
 
 所以，当我的UIViewController不是我的TabBarController的孩子时，一切都还可以：所有行都正确显示。 
 
 但是，当我将我的UIViewController设置为我的TabBarController的子TabBarController ，我遇到了这个错误：只显示了一些行（在所有情况下都会显示一个超过三十行）。 
 
 我只是不明白发生了什么。 我的代码似乎工作，但只有当我的UIViewController不是我的TabBarController的孩子。 
 
 在这种情况下是否还有其他方法可以添加？ 
 
 有我的UIViewController的代码： 
 
class ProfileController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet weak var tableChallenges: UITableView!
    @IBOutlet weak var profileTabs: UISegmentedControl!

    var pageViewController : UIPageViewController!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.tableChallenges.dataSource = self
        self.tableChallenges.delegate = self

        self.tableChallenges.reloadData()

    }

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

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5
    }

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

        let cell = tableView.dequeueReusableCellWithIdentifier("challengeCustomCell", forIndexPath: indexPath) as! ChallengeCustomCell

        switch(self.profileTabs.selectedSegmentIndex) {
            case 0:
                cell.challengeSuccededOrFailedImage.hidden = true
            break

            case 1:
                cell.challengeSuccededOrFailedImage.hidden = false
                cell.challengeSuccededOrFailedImage.image = UIImage(named: "challenge-succeded")
            break

            case 2:
                cell.challengeSuccededOrFailedImage.hidden = false
                cell.challengeSuccededOrFailedImage.image = UIImage(named: "challenge-failed")
            break

            case 3:
                cell.challengeSuccededOrFailedImage.hidden = true
            break

            default: break

        }

        return cell
    }

    @IBAction func selectedItemChanged(sender: AnyObject) {
        self.tableChallenges.reloadData()
    }
}
 
 在此先感谢您的回答！ :) 

I'm facing a bug with my UITableView in UIViewController. I'll try to explain what's the situation and my problem.
 
I have a TabBarController which a view is a UIViewController with a UITableView. I don't use a UITableViewController because I have some specifics controls on my UIViewController.
 
So, when my UIViewController isn't a child of my TabBarController, everything is okay : all rows are displayed correctly.
 
But, when I set my UIViewController as a child of my TabBarController, I have this bug : only some rows are displayed (one over threem exactly, in all scenarios). 
 
I just don't understand what's happening. My code seems working, but only when my UIViewController isn't a child of my TabBarController. 
 
Is there another method to add in this case ?
 
There is the code of my UIViewController :
 
class ProfileController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet weak var tableChallenges: UITableView!
    @IBOutlet weak var profileTabs: UISegmentedControl!

    var pageViewController : UIPageViewController!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.tableChallenges.dataSource = self
        self.tableChallenges.delegate = self

        self.tableChallenges.reloadData()

    }

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

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5
    }

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

        let cell = tableView.dequeueReusableCellWithIdentifier("challengeCustomCell", forIndexPath: indexPath) as! ChallengeCustomCell

        switch(self.profileTabs.selectedSegmentIndex) {
            case 0:
                cell.challengeSuccededOrFailedImage.hidden = true
            break

            case 1:
                cell.challengeSuccededOrFailedImage.hidden = false
                cell.challengeSuccededOrFailedImage.image = UIImage(named: "challenge-succeded")
            break

            case 2:
                cell.challengeSuccededOrFailedImage.hidden = false
                cell.challengeSuccededOrFailedImage.image = UIImage(named: "challenge-failed")
            break

            case 3:
                cell.challengeSuccededOrFailedImage.hidden = true
            break

            default: break

        }

        return cell
    }

    @IBAction func selectedItemChanged(sender: AnyObject) {
        self.tableChallenges.reloadData()
    }
}
 
Thanks in advance for your answers ! :)
