addArrangedSubview是重叠的视图
问题描述 投票：0回答：1
我的问题-当我以编程方式将安排的子视图添加到stackview时，它们只是堆积在右上角，如下所示。他们为什么不堆积呢？我已经尝试了很多方法，包括使用具有固有大小的视图。
堆栈视图称为mainStack，来自xib。 mainStack是一个垂直堆栈，其中“对齐”设置为“填充”，“分布”设置为“相等填充”（请参阅此问题底部的设置）。它包含一个带有蓝色背景的UIView。为了这个问题，我使用addArrangedSubviews向mainStack添加了两个视图。这是我得到的：
这是xib的代码：
class TaskSheet: UIView {
@IBOutlet var contentView: UIView!
@IBOutlet weak var mainStack: UIStackView!
override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
func setup() {
let nib = UINib(nibName: "TaskSheet", bundle: nil)
nib.instantiate(withOwner: self, options: nil)
contentView.frame = bounds
addSubview(contentView)
}
}
这就是我试图向mainStack添加视图的方式：
class PDFSheet: UIView {
var taskSheet: TaskSheet!
var sheetArray = [UIView]()
func makeSheet() -> [UIView] {
taskSheet = TaskSheet(frame: CGRect(x: 0, y: 0, width: 612, height: 792))
let newView1 = UIView(frame: CGRect(x: 0, y: 0, width: 240, height: 128))
newView1.heightAnchor.constraint(equalToConstant: 128).isActive = true
newView1.widthAnchor.constraint(equalToConstant: 240).isActive = true
newView1.backgroundColor = .green
let newView2 = UIView(frame: CGRect(x: 0, y: 0, width: 120, height: 64))
newView2.heightAnchor.constraint(equalToConstant: 64).isActive = true
newView2.widthAnchor.constraint(equalToConstant: 120).isActive = true
newView2.backgroundColor = .yellow
taskSheet.mainStack.addArrangedSubview(newView1)
taskSheet.mainStack.addArrangedSubview(newView2)
sheetArray.append(taskSheet)
return sheetArray
}
}
并且，这是显示stackview设置的xib，以防万一...

我想我知道你要干什么。
这里是一个例子...
xib布局（顶部标签，垂直堆栈视图，底部标签）：
堆栈视图的属性：
TaskSheet，PDFSheet和示例视图控制器的代码：
class TaskSheet: UIView {
@IBOutlet var contentView: UIView!
@IBOutlet var mainStack: UIStackView!
override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
func setup() {
let nib = UINib(nibName: "TaskSheet", bundle: nil)
nib.instantiate(withOwner: self, options: nil)
addSubview(contentView)
NSLayoutConstraint.activate([
// constrain contentView on all 4 sides with 8-pts "padding"
contentView.topAnchor.constraint(equalTo: topAnchor, constant: 8.0),
contentView.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -8.0),
contentView.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 8.0),
contentView.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -8.0),
])
}
}
class PDFSheet: UIView {
var taskSheet: TaskSheet!
var sheetArray = [UIView]()
override init(frame: CGRect) {
super.init(frame: frame)
_ = makeSheet()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
_ = makeSheet()
}
func makeSheet() -> [UIView] {
taskSheet = TaskSheet()
let newView1 = UIView(frame: CGRect(x: 0, y: 0, width: 240, height: 128))
newView1.heightAnchor.constraint(equalToConstant: 128).isActive = true
newView1.widthAnchor.constraint(equalToConstant: 240).isActive = true
newView1.backgroundColor = .green
let newView2 = UIView(frame: CGRect(x: 0, y: 0, width: 120, height: 64))
newView2.heightAnchor.constraint(equalToConstant: 64).isActive = true
newView2.widthAnchor.constraint(equalToConstant: 120).isActive = true
newView2.backgroundColor = .yellow
taskSheet.mainStack.addArrangedSubview(newView1)
taskSheet.mainStack.addArrangedSubview(newView2)
sheetArray.append(taskSheet)
addSubview(taskSheet)
taskSheet.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
// constrain taskSheet on all 4 sides
taskSheet.topAnchor.constraint(equalTo: topAnchor, constant: 8.0),
taskSheet.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -8.0),
taskSheet.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 8.0),
taskSheet.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -8.0),
])
return sheetArray
}
}
class TaskViewController: UIViewController {
var theSheetView: PDFSheet!
override func viewDidLoad() {
super.viewDidLoad()
theSheetView = PDFSheet()
theSheetView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(theSheetView)
let g = view.safeAreaLayoutGuide
NSLayoutConstraint.activate([
// constrain the sheet view on all top, leading, trailing with 32-pts "padding"
theSheetView.topAnchor.constraint(equalTo: g.topAnchor, constant: 32.0),
theSheetView.leadingAnchor.constraint(equalTo: g.leadingAnchor, constant: 32.0),
theSheetView.trailingAnchor.constraint(equalTo: g.trailingAnchor, constant: -32.0),
// NO height or bottom constraint
])
}
}
