我一直在尝试在SwiftUI中创建多行TextField，但是我不知道怎么做。

这是我目前拥有的代码：

struct EditorTextView : View {
    @Binding var text: String

    var body: some View {
        TextField($text)
            .lineLimit(4)
            .multilineTextAlignment(.leading)
            .frame(minWidth: 100, maxWidth: 200, minHeight: 100, maxHeight: .infinity, alignment: .topLeading)
    }
}

#if DEBUG
let sampleText = """
Very long line 1
Very long line 2
Very long line 3
Very long line 4
"""

struct EditorTextView_Previews : PreviewProvider {
    static var previews: some View {
        EditorTextView(text: .constant(sampleText))
            .previewLayout(.fixed(width: 200, height: 200))
    }
}
#endif

但这是输出：

我正在通过 UIViewRepresentable 为 SwiftUI 构建自定义 UITextView。它旨在显示NSAttributedString和处理链接按下。一切正常，但是当我在NavigationView带有内联标题的 a 中显示此视图时，框架高度完全混乱。

import SwiftUI

struct AttributedText: UIViewRepresentable {
  class Coordinator: NSObject, UITextViewDelegate {
    var parent: AttributedText

    init(_ view: AttributedText) {
      parent = view
    }

    func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
      parent.linkPressed(URL)
      return false
    }
  }

  let content: NSAttributedString
  @Binding var height: CGFloat
  var linkPressed: (URL) -> Void

  public func makeUIView(context: Context) -> UITextView {
    let textView = UITextView()
    textView.backgroundColor = .clear …
