The step-by-step guide on developing a React Native iOS sharing extension application

Is there a way to enable sharing from apps like WhatsApp, Skype, and Photos in my react-native app? I attempted to use react-native-share-extension, but it only seems to work with Safari.

What is the best method for implementing sharing functionality in iOS applications other than Safari using react-native?

Answer №1

After some troubleshooting, I managed to resolve the issue by inserting this code snippet into the info plist file:

<dict>
        <key>NSExtensionActivationRule</key>
        <dict>
            <key>NSExtensionActivationSupportsImageWithMaxCount</key>
            <integer>1</integer>
        </dict>
    </dict>

Answer №2

By default, react-native-share-extension enables sharing only URLs from browsers. However, if you wish for your extension to appear when sharing a URL, additional configuration is required.

For iOS, simply update the Info.plist file with the following:

<key>NSExtensionAttributes</key>
<dict>
  <key>NSExtensionActivationRule</key>
  <dict>
    <key>NSExtensionActivationSupportsWebURLWithMaxCount</key>
    <integer>1</integer>
  </dict>
</dict>

To verify the correct implementation, ensure this setting is reflected in XCode and allows for successful building:

Answer №3

The reason behind this is that the default configuration of this package is designed for sharing URLs to your application.

To customize the behavior, you will need to modify/extend the NSExtensionActivationRule in the Config.plist file of your share extension while continuing to use the react-native-share-extension package. More information on this key can be found directly from the author and also in the Apple documentation.

You have the flexibility to rewrite the rule entirely for specific file types like PDF files (as mentioned in the Apple docs):

<key>NSExtensionAttributes</key>
<dict>
    <key>NSExtensionActivationRule</key>
    <string>
        {extensionItems = ({
            attachments = ({
                registeredTypeIdentifiers = (
                    "com.adobe.pdf",
                    "public.file-url"
                );
            });
        })}
    </string>
</dict>
