Question

Easiest way to authenticate user in iPhone app?

Answer 1

+3 A:

In our application, we use Facebook and Twitter. Facebook Connect is great. Really easy to do authentication, just few lines of codes:

session = [FBSession sessionForApplication:myApiKey secret:myAppSecret delegate:self];

handle delegate:

- (void)session:(FBSession*)session didLogin:(FBUID)uid

and add the login button:

FBLoginButton* button = [[[FBLoginButton alloc] init] autorelease]; 
[self.view addSubview:button];

More info here.

The tricky part maybe the fql. But if you experienced about SQL before, it should not be a problem. I already have experience on SQL and it took me few hours to understand fql and post/get in facebook.

About Twitter, it is harder, because the Oauth Authentication requires more jobs from you. The Get API of Twitter is easy to start but hard to scale further, imo, but may not be your problem if you only care about user authentication

Currently, in Iphone, Twitter recommends us to use XAuth instead of OAuth because it creates better User Experience. More about XAuth and OAuth here. We used this library before for OAuth, but now when we change to XAuth, we stopped using it.

cool thanks! are you using other methods of logging in? or does your app only support Facebook Connect?

I just asked my colleague about Twitter and add it in:). Our app currently supports Facebook and Twitter but I mainly work on Facebook

Answer 2

A:

This is a very simple answer to this problem... Tell the user to get a real phone. Android or WP7 prehaps:)

wth? But don't tell me that if users use Android or WP7, they never need to do authentication, with Facebook, with Twitter, with your own server?

Hi, so cool. Thanks a lot for sharing

be careful a little bit about UX, because what I can see is the Facebook Login is not the one provided by FBConnect for iPhone. Users are get used to that login screen
