如何更改此 UIViewRepresentable 的高度？

Question

我在网上找到这段代码：

struct CustomTextField: UIViewRepresentable {
    @Binding var text: String
    @State var placeholder: String
    func makeCoordinator() -> Coordinator {
        Coordinator(text: $text)
    }

    func makeUIView(context: Context) -> UITextField {
        let textField = UITextField()
        textField.borderStyle = .roundedRect
        textField.placeholder = placeholder

        textField.autocapitalizationType = .none
        textField.autocorrectionType = .no
        textField.spellCheckingType = .no
        textField.keyboardType = .URL
        textField.frame = CGRect(x: 0, y: 0, width: 20.00, height: 10)
        textField.delegate = context.coordinator
        return textField
    }

    func updateUIView(_ view: UITextField, context: Context) {
        view.text = text
    }
}

extension CustomTextField {
    class Coordinator: NSObject, UITextFieldDelegate {
        @Binding var text: String

        init(text: Binding<String>) {
            _text = text
        }

        func textFieldDidChangeSelection(_ textField: UITextField) {
            DispatchQueue.main.async {
                self.text = textField.text ?? ""
            }
        }
    }
}

代码工作得很好。这个问题是我找不到合适的方法来增加它的高度。如您所见，我尝试使用 CGRect 作为框架，但没有效果。如何更改此自定义项的大小（特别是在我的特定情况下的高度）UIViewRepresentable?

Answer 1

就像您对任何其他 SwiftUI 视图所做的一样：

CustomTextField(text: $text, placeholder: "")
// constant
    .frame(height: 100)
// fill available height
    .frame(maxHeight: .infinity)

如果你想让它尊重 intrinsicContentSize，请查看 this answer
