Find Facebook SDK Version on iOS

Question

I know I\'m using the latest version (v3.2.1). But I want find it in header or programmatically.

In iOS I can\'t find version number in FacebookSDK.framework headers

Answer 1

For Facebook SDK 3.18, I had to do

#import <FacebookSDK/FacebookSDK.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    NSLog( @"My app is running FB sdk version: %@", [FBSettings sdkVersion]);
}

Answer 2

After about 2014, simply do this:

NSLog( @"### running FB sdk version: %@", [FBSDKSettings sdkVersion] );

For very old versions. Before about 3.6:

I found an undocumented way to print the SDK version (FB_IOS_SDK_VERSION_STRING), try this

NSLog(@"### FB SDK VERSION : %@",
    [[FBRequestConnection class] performSelector:@selector(userAgent)]);

Worked for me with sdk 3.5.1

Hope that helps...

Update: As of FB SDK 3.6, "The SDK version number is defined in FacebookSDK.h and available from [FBSDKSettings sdkVersion]"

Answer 3

You can find the version of your Facebook SDK in FBSDKCoreKit.h defined as

#define FBSDK_VERSION_STRING @"X.XX.X". Have a look at the image below.

Answer 4

If you are using pods you can check in the Info.plist file:

"Pods/FBSDKCoreKit/Support Files/Info.plist"

The version is the key CFBundleShortVersionString

My version was 4.18.0

Example:

<?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>CFBundleDevelopmentRegion</key>
  <string>en</string>
  <key>CFBundleExecutable</key>
  <string>${EXECUTABLE_NAME}</string>
  <key>CFBundleIdentifier</key>
  <string>${PRODUCT_BUNDLE_IDENTIFIER}</string>
  <key>CFBundleInfoDictionaryVersion</key>
  <string>6.0</string>
  <key>CFBundleName</key>
  <string>${PRODUCT_NAME}</string>
  <key>CFBundlePackageType</key>
  <string>FMWK</string>
  <key>CFBundleShortVersionString</key>
  <string>4.18.0</string>
  <key>CFBundleSignature</key>
  <string>????</string>
  <key>CFBundleVersion</key>
  <string>${CURRENT_PROJECT_VERSION}</string>
  <key>NSPrincipalClass</key>
  <string></string>
</dict>
</plist>

Answer 5

Take a look at FBSDKVersion.h. There's a define there:

#define FB_IOS_SDK_VERSION_STRING @"3.2.1"

Answer 6

For those running SDK version >= 4, [FBSDKSettings sdkVersion].

#import <FBSDKCoreKit/FBSDKCoreKit.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    NSLog(@"### Running FB SDK Version: %@", [FBSDKSettings sdkVersion]);
}
