如何进行文本换行？这是我的代码：

struct ContentView: View {
    private let items: [String] = [
        "OneLineLongggggggggggggggggggggggggggggggggggggggggg",
        "TwoLinesLonggggggggggggg\nLongggggggggggggggg",
        "ThreeLinesLonggggggggggggg\nLongggggggggggggggg\nLongggggggggggggggg"
    ]
    @State private var text: String = ""
    var body: some View {
        VStack {
            Picker("Select Text", selection: self.$text) {
                ForEach(self.items, id: \.self) {
                    Text($0)
                        .tag($0)
                }
            }
            Text("select: \(self.text)")
        }
    }
}

结果如下：

如果我添加 fixSize，那么元素会相互重叠：

struct ContentView: View {
    private let items: [String] = [
        "OneLineLongggggggggggggggggggggggggggggggggggggggggg",
        "TwoLinesLonggggggggggggg\nLongggggggggggggggg",
        "ThreeLinesLonggggggggggggg\nLongggggggggggggggg\nLongggggggggggggggg"
    ]
    @State private var text: String = ""
    var body: some View {
        VStack {
            Picker("Select Text", selection: self.$text) {
                ForEach(self.items, id: \.self) {
                    Text($0)
                        .tag($0)
                        .fixedSize(horizontal: false, vertical: true)
                }
            }
            Text("select: \(self.text)")
        }
    }
}

结果如下：

请告诉我从哪个方向寻找答案？

【解决方案1】：

请在文本中使用 .lineLimit（任意数量的最大行数）。

在这种情况下你可以使用

 Text($0)
    .tag($0)
    .lineLimit(3)

【讨论】：

它不起作用。对于一条很长的线路，这永远行不通。
我现在看到您希望在选择器中使用此功能。这不受支持。
