更新UIScrollView的高度

我在xib文件中有以下设置

ScrollView (UIScrollView)
    - ContentView (UIView)
        - ImageSlider (FSPagerView)
        - ClinicName (UILabel)
        - ClinicSlogan (UILabel)
        - LineSeparatorView (UIView)
        - ClinicProfile (UITextView)
        - SectionView (Custom UIView)
        - Doctors View (UICollectionView) - Horizontal Scrolling

约束按以下方式设置

// ScrollView Constraints
ScrollView.Top = NavigationView.Bottom
ScrollView.Leading = SafeArea.Leading
SafeArea.Trailing = ScrollView.Trailing
SafeArea.Bottom = ScrollView.Bottom

// ContentView Constraints
ContentView.Top = SuperView.Top
ContentView.Leading = SuperView.Leading
SuperView.Trailing = ContentView.Trailing
SuperView.Bottom = ContentView.Bottom
ContentView.Height = SuperView.Height (Priority@250)
ContentView.Width = SuperView.Width

ContentView中的子视图的所有约束都设置为与SuperView(ContentView)相关

viewDidLoad() 我正在更新cliniclampose和ClinicProfile的文本值,并更新height常量。这是可行的,但是当我更新滚动视图的高度时它不起作用,下面是我调用的代码 viewDidLoad()

self.clinicSloganLabelHeightConstraint.constant = estimatedFrameFor(
    text: self.clinicSloganLabel.text!,
    font: self.clinicSloganLabel.font!,
    width: self.clinicSloganLabel.frame.width
).height
self.clinicProfileTextViewHeightConstraint.constant = self.clinicProfileTextView.sizeThatFits(
    CGSize(width: self.clinicProfileTextView.frame.width, height: .infinity)
).height
self.scrollView.contentSize.height = 2000

在UIViewController子类中更新滚动视图的高度时,您能帮助我们朝着正确的方向前进吗?

谢谢你
