这是我想要实现的布局
Label1 UIView Label2 <- horizontally stack view
Label1 UIView Label2
Label1 UIView Label2
Label1 UIView Label2
Label1 UIView Label2
每个水平堆栈视图都包含标签和视图以及另一个标签。 之后,水平堆栈视图将添加到垂直堆栈视图中。
因此,所有布局都是垂直堆栈视图。
我想在UITableViewCell
内实现这一目标。这是我的代码:
let verticalStackView: UIStackView = {
let hsv = UIStackView()
hsv.axis = .vertical
hsv.alignment = .fill
hsv.distribution = .fill
hsv.spacing = 10
hsv.translatesAutoresizingMaskIntoConstraints = false
return hsv
}()
override func awakeFromNib() {
super.awakeFromNib()
for i in 1..<10 {
let dayLbl: UILabel = {
let l = UILabel()
l.text = "Day " + String(i)
l.font = UIFont.preferredFont(forTextStyle: .caption1)
l.translatesAutoresizingMaskIntoConstraints = false
return l;
}()
let progressBar: ProgressBar = {
let pb = ProgressBar(frame: CGRect(x: 0, y: 0, width: 200, height: 12))
pb.translatesAutoresizingMaskIntoConstraints = false
return pb;
}()
let gradeLbl: UILabel = {
let l = UILabel()
l.text = String(i)
l.font = UIFont.preferredFont(forTextStyle: .headline)
l.translatesAutoresizingMaskIntoConstraints = false
return l;
}()
let horizontalStackView: UIStackView = {
let hsv = UIStackView()
hsv.axis = .horizontal
hsv.alignment = .fill
hsv.distribution = .fill
hsv.spacing = 5
hsv.translatesAutoresizingMaskIntoConstraints = false
return hsv
}()
horizontalStackView.addSubview(dayLbl)
horizontalStackView.addSubview(progressBar)
horizontalStackView.addSubview(gradeLbl)
NSLayoutConstraint.activate([
horizontalStackView.heightAnchor.constraint(equalToConstant: 12)
])
verticalStackView.addSubview(horizontalStackView)
}
contentView.addSubview(verticalStackView)
NSLayoutConstraint.activate([
verticalStackView.topAnchor.constraint(equalTo: vcTitle.bottomAnchor, constant: 30),
verticalStackView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 20),
verticalStackView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: 20),
verticalStackView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: 30),
])
}
这就是我得到的:
它应该出现在&#34; Productivity Chart&#34;标题,但它出现在单元格内容视图x:0 y:0位置。而且只有一条线,一切看起来都很拥挤。
知道我做错了吗?
这是一行的外观:
Day 1 ----------------- 7
(where ----- is the view).
编辑:
用addSubView
替换addArrangedSubview
后:
编辑2:
截断的右侧部分也是固定的。我改变了:
verticalStackView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: 20)
到
contentView.trailingAnchor.constraint(equalTo: verticalStackView.trailingAnchor, constant: 20)
答案 0 :(得分:2)
在向UIStackView添加新子视图时,应使用addArrangedSubview方法。
堆栈视图确保arrangeSubviews数组始终为a 其子视图数组的子集。此方法自动添加 提供视图作为堆栈视图的子视图(如果尚未提供)。如果 视图已经是子视图,此操作不会改变 子视图排序。
