UIScroll在UIView做一些奇怪的事情

Question

我在IB上的UIView中有两个UIScrollViews。

每个UIScrollView都有水平按钮。 顶部UIScrollView上的按钮高度为70 底部UIScrollView上的按钮高度为60 然后添加一些填充，即10px

所以我将UIScrollViews设置为一个，其中一个按钮是视图的一半，另一个是UIScrollView中的按钮，但没有任何填充。

有关将UIScrollViews添加到UIView的任何建议，以便它们正确放置并且不进行任何垂直滚动（仅水平），并且按钮适合UIScrollView。

这是设置UIScrollViews的代码。

let scrollingView = ScrollViewEventType(CGSizeMake(62.0,62.0), buttonCount: 10)
        EventScroll.contentSize = scrollingView.frame.size
        EventScroll.addSubview(scrollingView)
        EventScroll.showsHorizontalScrollIndicator = false
        EventScroll.indicatorStyle = .Default


        let datescrollingview = ScrollViewDateType(CGSizeMake(124.0, 70.0), buttonCount: 6)
        DateScroll.contentSize = datescrollingview.frame.size
        DateScroll.addSubview(datescrollingview)
        DateScroll.showsHorizontalScrollIndicator = false
        DateScroll.indicatorStyle = .Default

这是针对两个UIScrollViews

func ScrollViewEventType(buttonSize:CGSize, buttonCount:Int) -> UIView {
        //creates color buttons in a UIView
        let padding = CGSizeMake(10, 10)
        let buttonView = UIView()
        DateScroll.backgroundColor = UIColor(red: 0.84, green: 0.90, blue: 0.95, alpha: 1.0)
        DateScroll.frame.origin = CGPointMake(0, 2)
        buttonView.frame.size.width = (buttonSize.width + padding.width) * CGFloat(buttonCount)
        buttonView.frame.size.height = (buttonSize.height +  padding.height)

        //add buttons to the view
        var buttonPosition = CGPointMake(padding.width * 0.5, padding.height)
        let buttonIncrement = buttonSize.width + padding.width


        for i in 0...(buttonCount - 1)  {
            var button = UIButton.buttonWithType(.Custom) as UIButton
            button.frame.size = buttonSize
            button.frame.origin = buttonPosition
            buttonPosition.x = buttonPosition.x + buttonIncrement
            button.backgroundColor = UIColor(red: 0.13, green: 0.48, blue: 0.81, alpha: 1.0)
            button.tag = i
            button.addTarget(self, action: "EventButtonPressed:", forControlEvents: .TouchUpInside)
            buttonView.addSubview(button)
        }
        return buttonView
    }
