In today's interconnected digital world, seamless sharing of content across apps has become a fundamental aspect of user experience. Whether it's sharing an interesting article, a captivating image, or a snippet of text, users expect to effortlessly transfer content between their favorite applications.
React Native, with its versatility and cross-platform capabilities, provides an excellent framework for building mobile apps that cater to these expectations. One powerful feature that React Native offers is the ability to implement Share Extensions Or Share Menu, allowing apps to receive content from other applications and integrate it seamlessly into their workflows.
In this comprehensive guide, we'll delve into the intricacies of implementing Share Extensions in React Native. From setting up your project to handling shared content, we'll walk you through each step of the process, equipping you with the knowledge to enhance your app's functionality and user experience.
Whether you're a seasoned React Native developer looking to expand your app's capabilities or a newcomer eager to explore the world of cross-app content sharing, this guide is designed to provide you with the insights and techniques you need to succeed.
Below is a step-by-step guide on how to implement a Share Extension or Share Menu in React Native
Create a new React Native project
npx react-native init YourProjectName
Install required package
npm i --save react-native-share-menu cd ios pod install
Add Share Extension Target to Xcode Project
Right-click on the project name in the project navigator and select "New Target".Choose "Share Extension" from the list of templates.Name your Share Extension target and click "Finish".
Next, Open the ShareViewController.swift and replace this code below
import UIKit
import Social
import SafariServices
import MobileCoreServices
class ShareViewController: SLComposeServiceViewController {
override func isContentValid() -> Bool {
// Do validation of contentText and/or NSExtensionContext attachments here
return true
}
override func viewDidLoad() {
didSelectPost()
}
override func didSelectPost() {
if let item = extensionContext?.inputItems.first as? NSExtensionItem {
if let attachments = item.attachments {
for attachment: NSItemProvider in attachments {
if attachment.hasItemConformingToTypeIdentifier("public.url") {
attachment.loadItem(forTypeIdentifier: "public.url", options: nil, completionHandler: { (url, error) in
if let shareURL = url as? NSURL {
// Do stuff with your URL now.
let url = NSURL(string: "schema://share/\(shareURL)")
let selectorOpenURL = sel_registerName("openURL:")
let context = NSExtensionContext()
context.open(url! as URL, completionHandler: nil)
var responder = self.parent as UIResponder?
while (responder != nil){
if responder?.responds(to: selectorOpenURL) == true{
responder?.perform(selectorOpenURL, with: url)
}
responder = responder!.next
}
}
self.extensionContext?.completeRequest(returningItems: [], completionHandler:nil)
//super.didSelectCancel()
})
}
if attachment.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
attachment.loadItem(forTypeIdentifier: (kUTTypeImage as String), options: nil, completionHandler: { (item, error) in
if let resultURL = item as? NSURL {
// if let itemImage = item as? UIImage{
let url = NSURL(string: "test.app.link://page1/\(resultURL)")
let selectorOpenURL = sel_registerName("openURL:")
let context = NSExtensionContext()
context.open(url! as URL, completionHandler: nil)
var responder = self.parent as UIResponder?
while (responder != nil){
if responder?.responds(to: selectorOpenURL) == true{
responder?.perform(selectorOpenURL, with: url)
}
responder = responder!.next
}
}
self.extensionContext?.completeRequest(returningItems: [], completionHandler:nil)
//super.didSelectCancel()
})
}
}
}
}
// self.extensionContext!.completeRequest(returningItems: [], completionHandler: nil)
}
override func didSelectCancel() {
super.didSelectCancel()
}
}
Configure AppDelegate.m
Next, In Xcode edit AppDelegate.m and add the following lines
#import <React/RCTLinkingManager.h> //Add this line
@implementation AppDelegate
//Add this code below
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
return [RCTLinkingManager application:application openURL:url options:options];
}
Configure Share Extension
Navigate to ShareExtension target in Xcode. Open Info.plist and add the following keys:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>NSAppTransportSecurity</key>
<dict>
<key>Allow Arbitraty Loads</key>
<true/>
</dict>
<key>NSExtension</key>
<dict>
<key>NSExtensionAttributes</key>
<dict>
<key>NSExtensionActivationRule</key>
<string>SUBQUERY(extensionItems,$extensionItem,SUBQUERY($extensionItem.attachments,$attachment,SUBQUERY($attachment.registeredTypeIdentifiers, $uti, $uti UTI-CONFORMS-TO "public.url" AND NOT $uti UTI-CONFORMS-TO "public.file-url").@count >= 1).@count >= 1).@count >= 1</string>
</dict>
<key>NSExtensionMainStoryboard</key>
<string>MainInterface</string>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.share-services</string>
</dict>
</dict>
</plist>
Example
const linking = {
prefixes: ['myapp://', 'https://yoururl.com'],
// Custom function to get the URL which was used to open the app
async getInitialURL() {
// As a fallback, you may want to do the default deep link handling
const url = await Linking.getInitialURL();
//console.log(url);
return url;
},
// Custom function to subscribe to incoming links
subscribe(listener: any) {
// Listen to incoming links from Firebase Dynamic Links
// Listen to incoming links from deep linking
const linkingSubscription = Linking.addEventListener('url', async ({ url }) => {
listener(url);
console.log(url,url.split('/')[5],'roc')
if (url.split('/').pop()) {
console.log(url.split('/')[5],'url')
}
});
return () => {
// Clean up the event listeners
// unsubscribeFirebase();
linkingSubscription.remove();
};
},
config: {
// Deep link configuration
},
};
