我正在尝试使UIStackView内的元素从中心位置相等。
这是我想要的效果:
如您所见,我希望两个文本字段彼此等距并在堆栈视图中居中对齐。
此堆栈视图将包含我需要排队的1-7个文本字段。
以下是当前发布的内容:
这是我设置文本字段的方式
let textLabel = UILabel()
textLabel.backgroundColor = UIColor.red
textLabel.widthAnchor.constraint(equalToConstant: 40.0).isActive = true
textLabel.heightAnchor.constraint(equalToConstant: 20.0).isActive = true
textLabel.text = "Hi"
textLabel.textAlignment = .center
let textLabel1 = UILabel()
textLabel1.backgroundColor = UIColor.red
textLabel1.widthAnchor.constraint(equalToConstant: 40.0).isActive = true
textLabel1.heightAnchor.constraint(equalToConstant: 20.0).isActive = true
textLabel1.text = "Hi"
textLabel1.textAlignment = .center
我正在像这样生成堆栈视图:
//Stack View
let stackView = UIStackView()
stackView.axis = UILayoutConstraintAxis.horizontal
stackView.distribution = UIStackViewDistribution.equalCentering
stackView.alignment = UIStackViewAlignment.fill
stackView.spacing = 16.0
stackView.addArrangedSubview(textLabel)
stackView.addArrangedSubview(textLabel1)
stackView.translatesAutoresizingMaskIntoConstraints = false;
self.view.addSubview(stackView)
//Constraints
stackView.leftAnchor.constraint(equalTo: self.view.leftAnchor, constant: 50).isActive = true
stackView.rightAnchor.constraint(equalTo: self.view.rightAnchor, constant: -50).isActive = true
stackView.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 100).isActive = true
如何获得内部的元素以使其居中对齐?
我以为是
UIStackViewDistribution.equalCentering
但是,那没什么大作用。
