The Mysterious Case of the Unresponsive “Done” Button: Solving the React-Native iOS Issue in Chrome

Have you ever encountered a situation where your perfectly crafted React-Native iOS app fails to respond to the “Done” button press in Chrome? You’re not alone! Many developers have stumbled upon this peculiar issue, leaving them scratching their heads and wondering what went wrong. Fear not, dear reader, for we’re about to embark on a journey to solve this enigma and get that “Done” button working like a charm.

Understanding the Problem

The issue lies in the way React-Native handles the onSubmitEditing event on iOS devices when accessed through Chrome. For some reason, the “Done” button on the iOS keyboard fails to trigger the onSubmitEditing event, leaving your app in a state of limbo. But don’t worry, we’ll get to the bottom of this and explore the solutions to this conundrum.

Why Does This Happen?

Before we dive into the solution, let’s take a step back and understand why this issue occurs in the first place. There are a few reasons why the “Done” button might not trigger the onSubmitEditing event:

• The keyboard is rendered by Chrome, not the native iOS keyboard, which can cause inconsistencies in event handling.

• The onSubmitEditing event is a native event that isn’t properly propagated to the React-Native layer.

• There might be a bug or limitation in the React-Native library that prevents the event from being triggered.

Solutions and Workarounds

Now that we’ve identified the possible causes, let’s explore some solutions and workarounds to get that “Done” button working:

Solution 1: Use `onBlur` Instead of `onSubmitEditing`

One simple solution is to use the onBlur event instead of onSubmitEditing. This event is triggered when the text input loses focus, which can be a suitable alternative in many cases.

import React, { useState } from 'react';
import { TextInput } from 'react-native';

const MyComponent = () => {
  const [inputValue, setInputValue] = useState('');

  const handleBlur = () => {
    console.log('Blur event triggered!');
    // Perform actions when the "Done" button is pressed
  };

  return (
     setInputValue(text)}
      onBlur={handleBlur}
      placeholder="Enter some text"
    />
  );
};

Solution 2: Create a Custom Keyboard Accessory View

Another solution is to create a custom keyboard accessory view that includes a “Done” button. This approach allows you to control the behavior of the “Done” button and trigger the desired action.

import React, { useState } from 'react';
import { TextInput, Keyboard, View, TouchableOpacity, Text } from 'react-native';

const MyComponent = () => {
  const [inputValue, setInputValue] = useState('');
  const [keyboardVisible, setKeyboardVisible] = useState(false);

  const handleDonePress = () => {
    console.log('Done button pressed!');
    // Perform actions when the "Done" button is pressed
    Keyboard.dismiss();
  };

  return (
    
  );
};

Solution 3: Use a Third-Party Library

If you’re not comfortable with creating a custom keyboard accessory view or using onBlur instead of onSubmitEditing, you can opt for a third-party library that provides a solution to this issue. One such library is react-native-keyboard-toolbar.

import React, { useState } from 'react';
import { TextInput } from 'react-native';
import { KeyboardToolbar } from 'react-native-keyboard-toolbar';

const MyComponent = () => {
  const [inputValue, setInputValue] = useState('');

  const handleDonePress = () => {
    console.log('Done button pressed!');
    // Perform actions when the "Done" button is pressed
  };

  return (
    
  );
};

Solution 4: Modify the React-Native Source Code (Advanced)

If you’re feeling adventurous and want to dive deep into the React-Native source code, you can modify the code to include a custom event handler for the “Done” button press. This approach requires a good understanding of the React-Native source code and is not recommended for beginners.

Conclusion

In this article, we’ve explored the mysterious case of the unresponsive “Done” button in React-Native iOS apps when accessed through Chrome. We’ve discussed the possible causes of this issue and presented four solutions and workarounds to get that “Done” button working. By implementing one of these solutions, you can ensure that your app provides a seamless user experience, even in the Chrome environment.

Additional Tips and Tricks

Here are some additional tips and tricks to keep in mind when working with React-Native and the iOS keyboard:

• Use keyboardShouldPersistTaps={true}

  to prevent the keyboard from dismissing when the user taps outside the text input.

• Use returnKeyType="done" to specify the return key type as “Done” on iOS devices.

• Use blurOnSubmit={true} to blur the text input when the “Done” button is pressed.
