TextEditor

Overview 概要

A text editor view allows you to display and edit multiline, scrollable text in your app’s user interface. By default, the text editor view styles the text using characteristics inherited from the environment, like font(_:), foregroundColor(_:), and multilineTextAlignment(_:).

You create a text editor by adding a TextEditor instance to the body of your view, and initialize it by passing in a Binding to a string variable in your app:

struct TextEditingView: View {
    @State private var fullText: String = "This is some editable text..."


    var body: some View {
        TextEditor(text: $fullText)
    }
}

To style the text, use the standard view modifiers to configure a system font, set a custom font, or change the color of the view’s text.

In this example, the view renders the editor’s text in gray with a custom font:

struct TextEditingView: View {
    @State private var fullText: String = "This is some editable text..."


    var body: some View {
        TextEditor(text: $fullText)
            .foregroundColor(Color.gray)
            .font(.custom("HelveticaNeue", size: 13))
    }
}

If you want to change the spacing or font scaling aspects of the text, you can use modifiers like lineLimit(_:), lineSpacing(_:), and minimumScaleFactor(_:) to configure how the view displays text depending on the space constraints. For example, here the lineSpacing(_:) modifier sets the spacing between lines to 5 points:

struct TextEditingView: View {
    @State private var fullText: String = "This is some editable text..."


    var body: some View {
        TextEditor(text: $fullText)
            .foregroundColor(Color.gray)
            .font(.custom("HelveticaNeue", size: 13))
            .lineSpacing(5)
    }
}
