Swift 如何定制UIScrollview'；s指示器位置？

我在tableview的单元格中有一个滚动视图

我正在尝试将scrollview的指示器的位置设置为顶部

我必须检查水平指示器

正如你所看到的。。。我想把位置调到最上面

我的自定义指示器：黑色和蓝色指示器

默认指示器：底部…灰色指示器

我还尝试使用该方法设置

scrollView.ScrollIndicationSets=UIEdgeInsets（顶部：30，左侧：0，底部：0，右侧：10）

我解决了我的问题

有两种方法

1。使用UIPageController

2。使用UIView制作自定义指示器。

class AdvertiseCell: UITableViewCell, UIScrollViewDelegate {

    var advArray = [PFFile]()
    var advSectionArray = [UIImageView]()




    //declaire Custom Indicator using UIView
    var scrollIndicator = UIView()
    var indicator = UIView()


    @IBOutlet weak var pagingView: UIScrollView!

    @IBOutlet weak var pageController: UIPageControl!

    override func awakeFromNib() {
        super.awakeFromNib()

        // Initialization code
        let pagingViewHeight = self.pagingView.frame.height
        let pagingViewWidth = self.pagingView.frame.width


        //set section size
        advSectionArray.append(UIImageView(frame: CGRectMake(5, 5 ,  pagingViewWidth-10, pagingViewHeight-10)))
        advSectionArray.append(UIImageView(frame: CGRectMake(pagingViewWidth * 1 + 5, 5 ,  pagingViewWidth-10, pagingViewHeight-10)))
        advSectionArray.append(UIImageView(frame: CGRectMake(pagingViewWidth * 2 + 5, 5 ,  pagingViewWidth-10, pagingViewHeight-10)))


        //add imageview
        self.pagingView.addSubview(advSectionArray[0])
        self.pagingView.addSubview(advSectionArray[1])
        self.pagingView.addSubview(advSectionArray[2])


        self.pagingView.contentSize = CGSizeMake(self.pagingView.frame.width * 3, self.pagingView.frame.height)




        self.scrollIndicator = UIView(frame: CGRect(x: 0, y: 0, width: pagingViewWidth, height: 3))
        self.indicator = UIView(frame: CGRect(x: 0, y: 0, width: pagingViewWidth / 3, height: 3))

        self.scrollIndicator.backgroundColor = UIColor.blackColor()
        self.indicator.backgroundColor = UIColor(red: 0.0/255, green: 109/255, blue: 242/255, alpha: 1)

        super.addSubview(scrollIndicator)
        super.addSubview(indicator)


        //It is very important!
        self.pagingView.delegate = self

        self.pageController.currentPage = 0
        self.pageController.numberOfPages = 3


        loadAdvertise()
    }


    func scrollViewDidScroll(sclView: UIScrollView) {
        let page:Int = Int(floor(sclView.contentOffset.x / UIScreen.mainScreen().bounds.size.width))
        self.pageController.currentPage = page


        let pages : CGFloat
        pages = CGFloat(self.pageController.numberOfPages)

        self.indicator.frame = CGRectMake(sclView.contentOffset.x / pages, 0, self.pagingView.frame.width / 3, 3);



    }

看看我的结果
