Adding unlimited lines in a Text (SwiftUI)

问题:

Just figuring out how I can achieve multiple lines of text in a Text. It seems like the Text has the same default as UILabel (one line), but I can't find any function which meets this criteria.

struct ContentView : View {
    var body: some View {
        VStack(alignment: .leading, spacing: 10) {
            HStack {
                Text("Avocado Toast").font(.system(size: 24))
            }
            // This Text does cut, and I wonder how I can achieve multiple rows
            Text("Ingredients: Avocado, Almond Butter, Bread")
                .font(.system(size: 20))

        }
    }
}

Edit

.lineLimit(X), did the trick. But is it possible to not set a specific amount, for instance. With just a 0?

回答1:

Use .lineLimit() to limit the amount of lines of text. It takes an optional Int (Int?) as an argument, and .lineLimit(nil) allows unlimited lines.

Edit: As of SwiftUI Beta 5, Text has a default line limit of nil, so text in Text will wrap by default.

回答2:

For wrapping Text in a Form .lineLimit(Int.max) did not work for me. It seems there needs to be some width for it to know when to wrap. I believe the official way is with .fixedSize:

Text(message)
    .fixedSize(horizontal: false, vertical: true)

The documentation states:

This example shows the effect of fixedSize(horizontal:vertical:) on a text view that is wider than its parent, preserving the ideal, untruncated width of the text view.

My text kept truncating even with no line limit applied. Wrapping my content in a ScrollView {} solved it.

Use this:

Text("Ingredients: Avocado, Almond Butter, Bread")
    .lineLimit(nil)

If that doesn't work, use this method:

Text("Ingredients: Avocado, Almond Butter, Bread")
    .fixedSize(horizontal: false, vertical: true)

If lineLimit(nil) is not working for you, try setting layoutPriority manually to whatever it suits you .layoutPriority(0.5)
