Fetching and Displaying Facebook Comments in an iPhone Native App via Facebook SDK

Introduction

In today’s digital age, social media platforms like Facebook play a crucial role in enhancing the user experience of web applications. One way to achieve this is by integrating Facebook comments into your app using the Facebook SDK. In this blog post, we’ll explore how to fetch and display Facebook comments in an iPhone native app using the Facebook SDK.

Background

To understand how to fetch and display Facebook comments, it’s essential to first understand the Facebook Comment Social Plugin. The plugin allows users to engage with comments on a specific web page (article) through their Facebook profile. This plugin is used in desktop versions of Facebook to facilitate commenting.

For mobile applications, however, integrating this plugin directly is challenging due to security concerns and limitations imposed by iOS. Instead, we need to rely on the Facebook SDK for fetching comments from the server and displaying them within our app.

Why it’s Complicated

While it may seem straightforward to integrate Facebook comments into an iPhone native app, there are several reasons why this process can be complicated:

• Security Concerns: The Facebook Comment Social Plugin is primarily designed for desktop applications, which means it relies heavily on user authentication and session management. When moving to mobile apps, we need to ensure that our implementation adheres to Apple’s guidelines and security standards.
• iOS Limitations: Mobile devices have strict app sandboxing policies, which can limit the functionality of third-party libraries like the Facebook SDK. This might require us to implement custom solutions or work around these limitations.

Connection to Article URL

To fetch comments for a specific article, we need to obtain the page ID of that article. Once we have this information, we can use it to query the Facebook Graph API and retrieve the corresponding comments.

Here’s an example code snippet in Objective-C that demonstrates how to connect the comment to the same article URL on the web:

NSDictionary *params = @[@"ids" : pageId];
self.connection =
    [FBRequestConnection
     startWithGraphPath:@"comments"
     parameters:params
     HTTPMethod:@"GET"
     completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
         // ...
}];

Fetching Next Page of Comments

When we fetch the first page of comments, we receive a JSON response that includes a URL for fetching the next page. We can use this URL to continue fetching more comments until there are no more pages available.

Here’s an example code snippet in Objective-C that demonstrates how to fetch the next page of comments:

FBRequest *fbRequest = [[FBRequest alloc] initWithSession:[FBSession activeSession]
                                                  graphPath:nil];
FBRequestConnection *connection = [[FBRequestConnection alloc] init];
[connection addRequest:fbRequest completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    // ...
}];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:moreCommentsURL];
connection.urlRequest = request;
[connection start];

Building Your Own Solution

While the Facebook SDK provides a convenient way to integrate comments into your app, we need to build our own solution for displaying these comments. This might involve implementing custom UI components or integrating with existing third-party libraries.

Some possible approaches include:

• Custom UI Components: Create custom UI components that display the fetched comments in a clean and engaging manner.
• Third-Party Libraries: Integrate with existing third-party libraries like react-native-fbsdk or pod-FacebookSDK to simplify comment fetching and display.

Conclusion

In this blog post, we explored how to fetch and display Facebook comments in an iPhone native app using the Facebook SDK. We discussed the challenges associated with integrating comments into mobile apps due to security concerns and iOS limitations. By understanding how to connect comments to article URLs and fetch next pages of comments, we can build our own solutions for displaying these comments.

Whether you choose to implement custom UI components or integrate with existing third-party libraries, the key takeaway is that fetching and displaying Facebook comments requires careful planning and execution.
