UIView中的中心标签，其y偏移状态栏的高度

Question

我很擅长快速尝试将标签和图像置于屏幕顶部的UIView中心。目前标签是垂直和水平居中的，因为这是我现在唯一可以做的事情。如您所见，我将autoresizing mask设置为约束为false并使用了centerXAnchor和-YAnchor。

但实际上我并不希望标签位于PostView的中心，而是以状态栏高度的y偏移为中心。所以它居中但没有y偏移状态栏的高度。因此，它看起来有点局促（？）：它非常接近状态栏...它看起来像这样：

但是我希望标签（以及后来的图像）在红色框中垂直居中：

这是我现在的代码（PostView class）：

override init(frame: CGRect){

    super.init(frame: frame)

    //add subview containing name (and image)
    infosContainerView.frame = frame
    addSubview(infosContainerView)

    //add sub view containing label to former UIView (infosContainerView)
    infosContainerView.addSubview(infoNameView)
    infoNameView.centerXAnchor.constraint(equalTo: centerXAnchor).isActive = true
    infoNameView.centerYAnchor.constraint(equalTo: centerYAnchor).isActive = true

}

//this UIView shall contain the infoNameView and infoImageView
let infosContainerView: UIView = {

    //set properties of controls container view
    let entireInfoView = UIView()
    entireInfoView.backgroundColor = .white

    return entireInfoView

}()


//label and properties of label with name (autoresizingmaskinto constraint set to false)
let infoNameView: UILabel = {

    //set properties of controls container view
    let nameView = UILabel()

    nameView.translatesAutoresizingMaskIntoConstraints = false
    nameView.backgroundColor = .white

    nameView.font = UIFont(name: "HelveticaNeue", size: 20)

    nameView.text = "Name"
    nameView.textColor = .black
    nameView.textAlignment = .center

    return nameView

}()

JožeWs已接近解决问题，而不是除以2，必须除以4虽然我不知道为什么......：

let statusBarHeight = UIApplication.shared.statusBarFrame.height

infosContainerView.addSubview(infoNameView)
infoNameView.centerXAnchor.constraint(equalTo: centerXAnchor).isActive = true
infoNameView.centerYAnchor.constraint(equalTo: centerYAnchor, constant: statusBarHeight/4).isActive = true

用

替换centerYAnchor约束init

// infoNameView.centerYAnchor.constraint(equalTo: centerYAnchor).isActive = true

   let statusBarHeight = UIApplication.shared.statusBarFrame.height
   infoNameView.centerYAnchor.constraint(equalTo: centerYAnchor, constant: statusBarHeight/2).isActive = true

这会将centerYAnchor的偏移量添加到等于statusBarHeight

的值
