Get Started - Facebook SDK for iOS
The Facebook SDK for iOS is the easiest way to integrate your iOS app with Facebook. It enables:
- Facebook Analytics - Understand how people are using your product.
- Facebook Login - Authenticate people with their Facebook credentials.
- Share and Send dialogs - Enable sharing content from your app to Facebook.
- App Events - Log events in your application.
- Graph API - Read and write to Graph API.
Before You Start
This procedure assumes you are using the latest version of iOS and Xcode. Learn more at the Apple Developer.
You will need:
- A Facebook for Developers Account If you need one, click this button and follow the steps.
- An App ID for Your App click this button and follow the steps to register your app and get an App ID
Step 1: Set Up Your Development Environment
- In Xcode, click File > Swift Packages > Add Package Dependency.
- In the dialog that appears, enter the repository URL: https://github.com/facebook/facebook-ios-sdk.
- In Version, select Up to Next Major and the default option.
- Complete the prompts to select the libraries you want to use in your project.
Step 2: Configure Your Project
Configure the
Info.plist file with an XML snippet that contains data about your app. - Right-click
Info.plist, and choose Open As ▸ Source Code. - Copy and paste the following XML snippet into the body of your file (
<dict>...</dict>). - In
<array><string>in the key[CFBundleURLSchemes], replace [APP_ID] with your App ID. - In
<string>in the keyFacebookAppID, replace [APP_ID] with your App ID. - In
<string>in the keyFacebookDisplayName, replace [APP_NAME] with the name of your app. - To use any of the Facebook dialogs (e.g., Login, Share, App Invites, etc.) that can perform an app switch to Facebook apps, your application's
Info.plistalso needs to include:<dict>...</dict>).<key>LSApplicationQueriesSchemes</key> <array> <string>fbapi</string> <string>fbapi20130214</string> <string>fbapi20130410</string> <string>fbapi20130702</string> <string>fbapi20131010</string> <string>fbapi20131219</string> <string>fbapi20140410</string> <string>fbapi20140116</string> <string>fbapi20150313</string> <string>fbapi20150629</string> <string>fbapi20160328</string> <string>fbauth</string> <string>fb-messenger-share-api</string> <string>fbauth2</string> <string>fbshareextension</string> </array>
Step 3: Connect the App Delegate
Replace the code in If you are using iOS 13 or above please add the following method to your SceneDelegate:
AppDelegate.swift with the following code. This code initializes the SDK when your app launches, and allows the SDK handle results from the native Facebook app when you perform a Login or Share action:
// Swift
//
// AppDelegate.swift
import UIKit
import FBSDKCoreKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
ApplicationDelegate.shared.application(
application,
didFinishLaunchingWithOptions: launchOptions
)
return true
}
func application(
_ app: UIApplication,
open url: URL,
options: [UIApplication.OpenURLOptionsKey : Any] = [:]
) -> Bool {
ApplicationDelegate.shared.application(
app,
open: url,
sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplication.OpenURLOptionsKey.annotation]
)
}
}
// Objective-C
//
// AppDelegate.m
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
return YES;
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
options:(nonnull NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options
{
[[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
options:options];
return YES;
}
// Swift
//
// SceneDelegate.swift
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
guard let url = URLContexts.first?.url else {
return
}
ApplicationDelegate.shared.application(
UIApplication.shared,
open: url,
sourceApplication: nil,
annotation: [UIApplication.OpenURLOptionsKey.annotation]
)
}
// Objective-C
//
// SceneDelegate.m
#import <FBSDKCoreKit/FBSDKCoreKit.h>
@import FacebookCore;
@interface SceneDelegate ()
@end
@implementation SceneDelegate
- (void)scene:(UIScene *)scene openURLContexts:(NSSet<UIOpenURLContext *> *)URLContexts
{
UIOpenURLContext *context = URLContexts.allObjects.firstObject;
[FBSDKApplicationDelegate.sharedInstance application:UIApplication.sharedApplication
openURL:context.URL
sourceApplication:context.options.sourceApplication
annotation:context.options.annotation];
}
Step 4: Build and Then Run Your Project in the Simulator
In Xcode, select an iOS simulator and click Run. Xcode builds your project and then launches the most recent version of your app running in Simulator.Step 5: See the Results in Events Manager
The Events Manager displays the events you send to Facebook Analytics. If this is the first time you launched your app with this code, you may have to wait at least 20 minutes before your events appear.
Note: Events may take up to 20 minutes to appear in the dashboard.
