如何以编程方式在滚动视图中嵌入堆栈视图

I have tried embedding it, but my stack view is dynamic and my app is also changing orientations time to time. I have segment control at the end of the view. I have also tried googling it but had no luck. thanks in advance.

我试过嵌入它,但我的堆栈视图是动态的,我的应用程序也在不断改变方向。我在视图的末尾有段控制。我也试过谷歌搜索但没有运气。提前致谢。

So far I have done:

到目前为止我做了:

In view did load:

在视图中加载:

mainStackView.axis = UILayoutConstraintAxis.Vertical
mainStackView.spacing = 3
scrollView.frame =  self.view.bounds
scrollView.addSubview(mainStackView)
view.addSubview(scrollView)

In view did layout:

在视图中做了布局:

override func viewDidLayoutSubviews()
    {
        super.viewDidLayoutSubviews()
        let top = topLayoutGuide.length
        let bottom = bottomLayoutGuide.length
                        self.mainStackView.frame = CGRect(x: 0, y: top, width: view.frame.width, height: view.frame.height - top - bottom).insetBy(dx: 10, dy: 10)
        dispatch_async(dispatch_get_main_queue())
            {

                self.scrollView.frame =  self.view.bounds
                self.scrollView.contentSize = CGSize(width: self.view.bounds.width, height: self.segmentedControl.frame.origin.y + self.segmentedControl.frame.height + 50)
        }
        print(scrollView.contentSize)
    }

You need to set the height constraint of segment control.

您需要设置段控制的高度约束。

For Example:

 segmentedControl.heightAnchor.constraintEqualToConstant(50).active = true

More over, you can Add Empty bottom view to avoid stack view's must fill mechanism. This will show you desired view output.

此外,您可以添加空底部视图以避免堆栈视图的必须填充机制。这将显示所需的视图输出。

        var bottomView = UIView(frame: CGRectZero)
        stackView.addArrangedSubview(bottomView)
