Facebook Login in ios application

[yugalkishoregoyal]

Hi,
I implemented Instagram Login in my app , that worked like charm !! Thanks for it :)
Now I'm implementing facebook login , I'm copying this code in my appdelegate( am I doing it right ?).
SimpleAuth.configuration()["facebook"] = [
"app_id" : ""
]
It is saying " Called Object type NSMutableDictionary is not a function or a function pointer "
I'm going to test it on simulator , will it work ?

[calebd]

Sorry about that. Pushing an update to CocoaPods right now.

[calebd]

Done!

$ pod update SimpleAuth

Hi,
Thanks for the quick response.
But it did't resolved the issue. I'm attaching a screenshot if that helps you in understanding the problem.

[calebd]

You can't type Swift into Objective-C files.

[calebd]

You want SimpleAuth.configuration[@"facebook"] = @{};

[yugalkishoregoyal]

Hi,
That worked !! Thanks !
Sorry to bother you again , but in Instagram we have access token in the responseObject.
How do we access profile picture or Display name of user in facebook ?

[calebd]

The Facebook response object is built here. Refer to that for all keys that you can use as a SimpleAuth consumer.

[yugalkishoregoyal]

I've tried the keys but I keep getting NS Exception error " this class is not key value coding-compliant for the key token.'
can you help me how to correctly access the keys ?
Thanks.

[calebd]

It's just a dictionary...

SimpleAuth.authorize("facebook", completion: { responseObject, error in
    let dictionary = responseObject as? [String: AnyObject]
    let credentials = dictionary?["credentials"] as? [String: AnyObject]
    let token = credentials?["token"] as? String
    println("\(__FUNCTION__) \(token)")
})

Or Objective-C if you're into that kind of thing:

[SimpleAuth authorize:@"facebook" completion:^(id responseObject, NSError *error) {
    NSDictionary *dictionary = responseObject;
    NSString *token = dictionary[@"credentials"][@"token"];
    NSLog(@"%s %@", __PRETTY_FUNCTION__, token);
}];

[yugalkishoregoyal]

I tried that method before , it is returning null.

[calebd]

Have you tried logging responseObject to see what it's structure is? It's possible that the request is failing along the way. In that case, responseObject will be nil and error will contain some potentially useful information.

[yugalkishoregoyal]

Yes tried, it is returning null only.

[calebd]

And the error?

[yugalkishoregoyal]

Hi,
When I tried to logging the error , I got following issues.

1. When I used account other than the account from which I created the application. I got following error.
   

2. When I used same account from which I created the facebook application, it hits the NSexception.

Can you confirm what version of SimpleAuth you have installed?

[yugalkishoregoyal]

Its the latest version.. I have installed it 2 days ago.

[calebd]

The most recent time you installed it isn’t really relevant. CocoaPods will lock pods to their initial versions unless you update them explicitly. Can you either confirm which version you have installed, or run pod update SimpleAuth?

[yugalkishoregoyal]

Its 0.3.9

[calebd]

It works fine for me... Can you paste the exception stack trace?

[yugalkishoregoyal]

Hi,
I'm not sure if its the exception stack trace you are talking about.

Ok. This bug was only present in 0.3.8, fixed in 0.3.9 (9b7830b). So maybe you need to clean your build, nuke derived data, or something. This works in 0.3.9. Maybe try a clean and see if that helps?

[yugalkishoregoyal]

That worked :))
Can we access facebook friend list with your pods ?

[calebd]

Sorry for the confusion. Yay Xcode.

Yep! Once you have the access token you can make any request to the graph API that you have permission for from the user. Just sign the request like you would any other and you're all set!
