创建具有重叠圆的视图

Question

我正在尝试创建一个简单的UIView行，然后在它上面创建一个圆圈。但是，我不确定我是如何在不产生等级​​问题的情况下绘制圆圈的？到目前为止我在下面，jut创建了行

订单

    self.stepLine = UIView()
    self.stepLine.translatesAutoresizingMaskIntoConstraints = false
    stepView.addSubview(self.stepLine)

    self.stepLine.backgroundColor = Color.theme.value

    self.stepLine.bottomAnchor.constraint(equalTo: stepView.bottomAnchor, constant: -4).isActive = true
    self.stepLine.heightAnchor.constraint(equalToConstant: 6).isActive = true
    self.stepLine.leftAnchor.constraint(equalTo: stepView.leftAnchor).isActive = true



override func layoutSubviews() {
    self.stepLine.widthAnchor.constraint(equalToConstant: self.frame.width/2).isActive = true
}

Answer 1

MainPage::MainPage()
{
  InitializeComponent();

  auto vec = ref new Platform::Collections::Vector<StudentWrapper^>();
  vec->Append(ref new StudentWrapper(Student(L"Alice")));
  vec->Append(ref new StudentWrapper(Student(L"Bob")));
  vec->Append(ref new StudentWrapper(Student(L"Chris")));

  students->ItemsSource = vec;
}

或其一些变化。但考虑到您所呈现的代码的性质，这是我建议的一般概念。
