I am new in iphone application. I want to make a simple application in which User can login from google and facebook. I have integrate API's for both of them. I have also completed the facebook connection but I dont know how to validate the Google user with its API (Gdata).
Can anybody please help me for authentication of google account using iphone application.I just want to check wether user is valid google user or not that's it. Please help me for that.
Thanks in advance..
Google supports OpenID, though that is typically just used by websites.
There is also authentication for Google accounts called ClientLogin; the Objective-C GData library provides routines to authenticate via ClientLogin to a Google account for use with a specific Google service API.
What is it that your application will do for authenticated users that it would not do for unauthenticated users?

I'm trying to make a chatbot with Dialogflow for Google Home. It requires the user to input a URL. Now it will definitely be a long and complicated URL which I can't recreate and I can't have the user speak into the google home.
The idea I had was that the user would input the URL on an agent on messenger. I store this on a Firebase database and then access it with a second agent.
Now the issue I have is authentication, I was hoping to use account linking on my google action with facebook. But I can't login to Facebook with google home. Or if I can, I can't find any documentation specific to that case. Facebook doesn't provide the necessary client ID and secret(as far as I can see).
I managed amazon and Gmail account linking with Alexa and an Amazon Echo. In those cases, you would have to login to google or amazon on the Alexa app or webpage. Then this will be integrated with your Echo and the skill will become usable.
Anyone have an idea of how I can make the link happen, if not then anyone have an idea as to how I can solve the overall problem?
This question has been left unanswered on other forums, but I was hoping to either get it solved or find an alternative.
There are three approaches to solving your overall problem - getting the URL manually entered and available to your Action. Two of them tackle it the way you've suggested - involving authenticating to Facebook and tying that to the Assistant account somehow. One solves it entirely inside the Assistant.
Account linking to the Facebook account
You've tagged firebase-authentication, so I'm going to assume that you're using it to do the auth and you've enabled Facebook login through it. This means your user has a "Firebase Account", but they log into that account using Facebook.
I will assume you have a way to get the URL from messenger once they're logged in.
The trick in this case is to setup Account Linking between their Firebase account and their Assistant account. This is done by setting up an OAuth2 server that has access to the Firebase accounts and will create authorization and refresh tokens that are given to the Assistant.
In the Action, you'll send the user to the Sign In helper, which will redirect them to your login page and send back a one-time auth code to the Assistant. The assistant will then use your OAuth2 server to exchange this code for auth and refresh tokens. Periodically it will use the refresh token to get new auth tokens.
When the user returns to the conversation through the Assistant, you'll be handed an auth token and you can use this to lookup the user. Since you also know their Facebook account, you can get the URL via however you planned to do so.
There are drawbacks to this method - it is very complicated, and setting up your own OAuth2 server is not for the faint of heart. You may be able to use something like Auth0 instead of Firebase Authentication to accomplish the same thing, but then you don't have the ease of access to the Firebase database.
Account linking to both Facebook and Google
In your Firebase account, however, you don't need to limit them to just logging into Facebook. You can have them use Firebase to record both the Facebook and Google accounts that they're using. This would "link" the two accounts together in your system.
With this, you don't need to setup an OAuth2 server. Instead, you can have the Assistant use Google Sign In for authentication. If the Google Cloud Project that Firebase is using and the Assistant are using are the same project, then once the user has logged in to your project's web page with their Google account, you'll get an identity token on the Assistant which will contain their Google ID. You can use this to match up with their Firebase account and get the Facebook ID and proceed from there.
But this is still a lot of work and kinda messy, jumping between systems.
Using just the Google Assistant (and maybe a web page)
If you're willing to make some assumptions about the devices your users are using, then you may be able to do it all just using the Assistant. The Assistant doesn't just run on the Google Home and other smart speakers, it also works on most current Android and iOS devices.
So you can detect if they have such a device available and, if they do and they're not currently on it, direct them to switch to that device when you need the URL.
If they don't have such a device available (perhaps because their version of Android is older), and you think this may be a common scenario, you may need to make another entry source available. This could be one of the solutions above, or you may want to just have a simple web page (done via Firebase Hosting and Firebase Functions, perhaps) where they log in using their Google account (so you get their ID) and you let them enter the URL. If you just need a URL - going through Dialogflow may be more complexity than you need.
I have been making Google Home apps, but now I want to make apps that are connected to Firebase server and DialogFlow API. How is it possible to integrate user authentication in an ios app to identify that user who is using Google Home with that login state?
For example, if I make a restaurant ordering app, I want any user to make a request through Google Home and the user can check his/her ordering history on an ios app.
A user logs in through an app and then how does google home detect that user as a logged in user? I have been searching how to implement this, but nothing hits.
You will need to implement account linking for Actions on Google. This will require two server-side components that you'll need to build:
You'll need to create an OAuth server that will allow the user to authenticate to your service (and use Firebase auth as a component of this) and authorize the Google Assistant to access your service. It does this by generating tokens that it hands to the Assistant.
Your Dialogflow fulfillment webhook will get this token passed to it as part of the conversation. It uses this token to determine which user is making the request and confirm it is valid.
There are OAuth services that are available that work with Google's auth that you should be able to fit in here, or you can write your own using Firebase Hosting and Firebase Cloud Functions. The Dialogflow webhook can, of course, be done using Firebase Cloud Functions.
I am developing one iPhone application in which I want to post data on the salesforce database.
I have tried from google but not got any success.
Can you please guide me?
Thanks in Advance
Salesforce provides an iOS SDK to talk to their API:
https://github.com/forcedotcom/SalesforceMobileSDK-iOS
Here is a tutorial on getting started:
http://wiki.developerforce.com/page/Getting_Started_with_the_Mobile_SDK_for_iOS
You will need to use an Oauth flow to authenticate to the API. This means you show a Login page from Salesforce.com, the user logs in, and then your UIWebView will get a redirect with a sessionId in the URL. You can extract the sessionId and use it to talk to the API for read or write access, depending on the user's permissions. The SDK includes sample code that implements all of that, so you just need to merge that code in with your app.
I want to make my application to run using Google credentials.
I'm doing an application where user can get his list of events from the server by giving local credentials. I want to make my application run when the user enters Google credentials.
How can integrate that to my application.
You can give a try on Google Data objective C API.. Which handles all google service. i guess you can handle google credentials here..
I am working on an iPhone application that uses Google app engine to host the backend. I need to authenticate with Google but I can't seem to find a way to do it from my app. It seems I am down to making a UIWebView to have a user sign in to the redirected login page I am getting from Google, but I would much rather have the user enter there credentials one time and then have it persist, unless the user signs out.
Is this possible? Should I be looking at other options or am I just not handling the redirect correctly?
Any suggestions or info would be appreciated.
Thanks
O-Auth is available on App Engine.
Just insert GTMOAuth in your projet and present the GTMOAuthViewControllerTouch. You'll be able to store the auth token in the user's keychain.
Then authorize your NSURLMutableRequests via [auth authorizeRequest:myNSURLMutableRequest]...
I think it might be easier than reusing and managing cookies.
This page has pretty complete information on how to access the built-in Signin flow that is included with the generated app-engine endpoint library:
