SwiftUI:如何调整UIViewRepresentable输出的大小？

struct MyView: UIViewRepresentable {
    func makeUIView(context: Context) -> UIView {
        let view = UIView()
        view.frame = CGRect(x: 0, y: 0, width: 200, height: 200) // 设置视图的大小为200x200
        return view
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        // 更新视图的内容
    }
}

struct MyView: UIViewRepresentable {
    func makeUIView(context: Context) -> UIView {
        let view = UIView()
        
        // 添加Auto Layout约束
        view.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            view.widthAnchor.constraint(equalToConstant: 200), // 设置宽度为200
            view.heightAnchor.constraint(equalToConstant: 200), // 设置高度为200
            // 添加其他约束...
        ])
        
        return view
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        // 更新视图的内容
    }
}
