For ios you need to add this to your app.ios to initialize the SDK
var application = require("application");
class MyDelegate extends UIResponder implements UIApplicationDelegate {
public static ObjCProtocols = [UIApplicationDelegate];
applicationDidFinishLaunchingWithOptions(application: UIApplication, launchOptions: NSDictionary): boolean {
return FBSDKApplicationDelegate.sharedInstance().applicationDidFinishLaunchingWithOptions(application, launchOptions);
}
applicationOpenURLSourceApplicationAnnotation(application, url, sourceApplication, annotation) {
return FBSDKApplicationDelegate.sharedInstance().applicationOpenURLSourceApplicationAnnotation(application, url, sourceApplication, annotation);
}
applicationDidBecomeActive(application: UIApplication): void {
FBSDKAppEvents.activateApp();
}
applicationWillTerminate(application: UIApplication): void {
//Do something you want here
}
applicationDidEnterBackground(application: UIApplication): void {
//Do something you want here
}
}
application.ios.delegate = MyDelegate;
application.start();
Add to your Info.plist(the one inside platforms/ios/yourApp) the Facebook App ID credentials
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb{your-app-id}</string>
</array>
</dict>
</array>
<key>CFBundleVersion</key>
<string>1.0</string>
<key>FacebookAppID</key>
<string>{your-app-id}</string>
<key>FacebookDisplayName</key>
<string>FacebookLoginDemo</string>
<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbauth2</string>
<string>fbapi</string>
<string>fb-messenger-api</string>
<string>fbshareextension</string>
</array>
For more information you can consult the official Facebook page for iOS https://developers.facebook.com/docs/ios
Add to your AndroidManifest.xml (the one inside platforms/android/src/main) the Facebook App ID credentials
<uses-permission android:name="android.permission.INTERNET"/>
application android:label="@string/app_name" ...>
...
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name" />
</application>
Add to your Strings (platforms/android/src/main/res/values/strings.xml) your facebook app id
<string name="facebook_app_id">your-app-id</string>
For more information you can consult the official Facebook page for Android https://developers.facebook.com/docs/android
Require the plugin whenever you want to use it
var FacebookLoginHandler = require("nativescript-facebook-login");
Create the callbacks to handle the result of the login
var successCallback = function(result) {
//Do something with the result, for example get the AccessToken
var token;
if (topmost().android){
token = result.getAccessToken().getToken();
}
else if (topmost().ios){
token = result.token.tokenString
}
alert(token);
}
var cancelCallback = function() {
alert("Login was cancelled");
}
var failCallback = function(error) {
var errorMessage = "Error with Facebook";
//Try to get as much information as possible from error
if (error) {
if (topmost().ios) {
if (error.localizedDescription) {
errorMessage += ": " + error.localizedDescription;
}
else if (error.code) {
errorMessage += ": Code " + error.code;
}
else {
errorMessage += ": " + error;
}
}
else if (topmost().android) {
if (error.getErrorMessage) {
errorMessage += ": " + error.getErrorMessage();
}
else if (error.getErrorCode) {
errorMessage += ": Code " + error.getErrorCode();
}
else {
errorMessage += ": " + error;
}
}
}
alert(errorMessage);
}
And finally you can start the login process like this
//Here we select the login behaviour
//Recomended system account with native fallback for iOS
if (topmost().ios) {
FacebookLoginHandler.init(2);
}
//Recomended default for android
else if (topmost().android) {
FacebookLoginHandler.init();
}
//Register our callbacks
FacebookLoginHandler.registerCallback(successCallback, cancelCallback, failCallback);
//Start the login process
FacebookLoginHandler.logInWithPublishPermissions(["publish_actions"]);
Sometimes the .aar library with the sdk for android don't get linked to the platform after installing the plugin. This end up in the error:
TypeError: Cannot read property 'FacebookSdk' of undefined
File: "/data/data/com.ladeezfirstmedia.ThisOrThat/files/app/tns_modules/nativescript-facebook-login/facebook-handler.js line: 9 column:16
You can try to sync the platform tns livesync android
You can try cleaning the platform. -remove the plugin -remove the platform -add the plugin -add the platform in that order
You can try to add manually the dependency change the build.gradle (platforms/android/build.gradle) like this:
dependencies {
....
....
compile "com.android.support:support-v4:$suppotVer"
compile "com.android.support:appcompat-v7:$suppotVer"
//Facebook sdk
compile 'com.facebook.android:facebook-android-sdk:4.6.0'
....
....
}
After installing the plugin CocoaPods creates a .xcworkspace file, use this one to open the project in Xcode instead of the .xcodeproj
