TextInput value cannot be manipulated via setNativeProps after user input on iOS

[mhoran]

Description

When an uncontrolled TextInput has had its value manipulated via setNativeProps, receives user input and is then manipulated again via setNativeProps, the displayed value does not change.

This looks to be a New Arch issue and the issue is not reproducible in 0.76.0 on the old architecture.

Steps to reproduce

1. Install the application with yarn ios
2. Press "Press me!"
3. Note that the TextInput contains the text "bananas"
4. Clear the input field
5. Press "Press me!"
6. Note that the input field remains empty

I am facing a similar issue, however in my case, text is being updated without issues, but when I update selection using setNativeProps, it messes things up....

On Android: the selection is not updated at all
On iOS: the behaviour is more confusing, the cursor jumps all over the place

RN version 0.79.0
Issue started appearing after enabled New Architecture.

Any ideas

Im having the same problem, using setNativeProps does not change the text of the TextInput.

Hi,
I had the same issue.
Seems it's an issue with textinput event counts in new fabric on iOS.

This work around fixed it for me

RefManager.composerInput.current?.setNativeProps({ text: text + '\u200B' });
// runs again and sees "value" != "value\u200B" -> emits new state -> applies.
requestAnimationFrame(() => {
    RefManager.composerInput.current?.setNativeProps({ text });
});
