Is there a way that I can limit the text to 2 / 3 lines using SwiftUI?

问题

I am trying using

var body: some View {
    Text("This is large text. Is there a way that I can unwrap the large text as discussed").lineLimit(2)
}

FYI: I knew

var body: some View {
    Text("This is large text. Is there a way that I can unwrap the large text as discussed").lineLimit(nil)
}

It will wrap the text to say n number of lines.

回答1:

Call .lineLimit(3) on the Text element. (Technically, it can be called on any View, in which case it will limit the lines of all Text elements in that view.)

From SwiftUI.View:

    /// Sets the maximum number of lines that text can occupy in this view.
    ///
    /// The line limit applies to all `Text` instances within this view. For
    /// example, an `HStack` with multiple pieces of text longer than three
    /// lines caps each piece of text to three lines rather than capping the
    /// total number of lines across the `HStack`.
    ///
    /// - Parameter number: The line limit. If `nil`, no line limit applies.
    /// - Returns: A view that limits the number of lines that `Text` instances
    ///   display.
    public func lineLimit(_ number: Int?) -> Self.Modified<_EnvironmentKeyWritingModifier<Int?>>
