Text

This deprecated feature is only supported in the Legacy Runtime, not the New Runtime.

DEPRECATION NOTICE: This entire page documents the legacy Text manipulation system. For new projects: Use Data Binding instead. For existing projects: Plan to migrate from direct text run manipulation to Data Binding as soon as possible.

For more information on designing and animating Text, please refer to the editor’s text section:

Read/Update Text Runs at Runtime

⚠️ LEGACY CONTENT WARNING: The following sections document the deprecated Text manipulation system. This content is provided for legacy support only. New implementations should use Data Binding.

If you intend to update a text run at runtime it’s important to manually enter a unique name for the run in the editor: And then export the name: right-click and select Export name You can identify an exported component if it’s surrounded by square brackets. This makes it possible for the run to be “discoverable” at runtime by its name. For more information, see Exporting for Runtime.

If the name is not set manually in the editor the name will not be part of the exported .riv (to reduce file size).

Text runs can also be updated on components at runtime, see Read/Update Nested Text Runs at Runtime below.

Reading Text

To read a given text run text value at any given time, reference the .getTextRunValue() API on the RiveViewModel:

open func getTextRunValue(_ textRunName: String) -> String?

Supply the text run name and you’ll have the Rive text run value returned, or nil if the text run could not be queried.

Setting Text

To set a given text run value at any given time, reference the .setTextRunValue() API on the RiveViewModel:

open func setTextRunValue(_ textRunName: String, textValue: String) throws

Supply the text run name and a second parameter, textValue, with a String value that you want to set the new text value for.

If the supplied textRunName Rive text run cannot be queried on the active artboard, Rive will throw a RiveError.textValueRunError that you may need to catch and handle gracefully in your application.

Example Usage

@State private var userInput: String = ""
@State private var rvm = RiveViewModel(fileName: "my-rive-file")

var body: some View {
    VStack(spacing: 20) {
        Text("Enter text:")
            .font(.headline)
        TextField("Enter text...", text: $userInput)
            .textFieldStyle(RoundedBorderTextFieldStyle())
            .padding()
            .onChange(of: userInput, perform: { newValue in
                if (!newValue.isEmpty) {
                    try! rvm.setTextRunValue("MyTextRunName", textValue: userInput)
                }
            })
        rvm.view()
    }
}

Read/Update Nested Text Runs at Runtime

⚠️ DEPRECATED FEATURE: Nested Text Runs are part of the legacy Text manipulation system. Use Data Binding instead for controlling component text properties at runtime.

It’s possible to set nested text runs at runtime—text that is not on the main artboard but on a Component. To set a nested text run, you’ll need to take note of the path where the input exists at an artboard level. For example, to get/set the text run named button_text on the Button artboard, you need to provide the correct path. Setting Nested Text Runs The artboard names here are:

Main -> NestedArtboard -> Button

However, the path is determined based on the names set in the hierarchy:

ArtboardWithUniqueName -> ButtonWithUniqueName

The path is then: ArtboardWithUniqueName/ButtonWithUniqueName

Be sure to mark the components and text runs as exported.

Export component name

Do not use ”/” in the name for your components, as that will break the search functionality at runtime.

Reading Text

Similar to reading text from a text run within a parent artboard, you can set the value of a text run within a component instance using the following API:

open func getTextRunValue(_ textRunName: String, path: String) -> String?

Setting Text

Additionally, similar to setting text within a parent artboard, you can read the value of a text run within a component instance using the following API:

open func setTextRunValue(_ textRunName: String, textValue: String, path: String) throws

Example:

@State private var userInput: String = ""
@State private var rvm = RiveViewModel(fileName: "my-rive-file")

var body: some View {
    VStack(spacing: 20) {
        Text("Enter text:")
            .font(.headline)
        TextField("Enter text...", text: $userInput)
            .textFieldStyle(RoundedBorderTextFieldStyle())
            .padding()
            .onChange(of: userInput, perform: { newValue in
                if (!newValue.isEmpty) {
                    try! rvm.setTextRunValue("MyTextRunName", textValue: userInput, path: "Artboard/NestedArtboard")
                }
            })
        rvm.view()
    }
}
