如何将UIView调整为特定的高度和宽度,包括其子视图?

不要忘记为 subView

subView.autoresizesSubviews = true;

根据 Apple documentation

一个整数位掩码,用于确定接收器如何调整自身大小 当其SuperView边界更改时。

所以用你的例子来看

let containerView = UIView(frame: CGRect(x:0, 
                                         y:0, 
                                         width: self.view.bounds.width, 
                                         height: self.view.bounds.height))

containerView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
self.view.addSubview(containerView)

let subView = UIView(frame: CGRect(x:0, 
                                   y:0, 
                                   width: containerView.bounds.size.width / 2, 
                                   height: containerView.bounds.size.height))

subView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
subView.autoresizesSubviews = true;
containerView.addSubview(subView)

通过使用 UIStackView 。

let stackView = UIStackView(frame: .zero)
currentPage.addSubview(stackView)
constraintViewToSuperView(view: stackView) // my helper function to constraint stackview to bounds of parent

stackView.axis = .vertical
stackView.alignment = .fill
stackView.distribution = .fillProportionally
stackView.spacing = 1
stackView.backgroundColor = .red

关键是要约束 UIStackview 进入父母的界限。然后,我对父对象所做的任何调整也会按比例调整 UIStackview 的孩子。
