Hi, thanks for your time to answer my question.

I've got an error when I tried to load the session

HTTP Status 400: Bad Request, Response: {"errors":[{"message":"Bad Authentication data","code":215}]}

if I change the codes when I load the session to this

let swifter = Swifter(consumerKey: myConsumerKey, consumerSecret: myConsumerSecret)
swifter.client.credential = credential

I got this error

HTTP Status 401: Unauthorized, Response: {"errors":[{"message":"Could not authenticate you","code":32}]}

do you know where is the problem?

from swifter.

umm.
there is a possibility that you tweet without setting the write permissions.

Hello s-aska,

I have tried to update twitter session with your code, here is mine :

        let key = "my-twitter-from-keychain"
        let secret = "my-twitter-secret-from-keychain"
        let accessToken = SwifterCredential.OAuthAccessToken(key: key!, secret: secret!)
        let credential = SwifterCredential(accessToken: accessToken)

         self.swifter = Swifter(consumerKey: "my-key", consumerSecret: "my-secret")
        swifter.client.credential = credential

But this seem not working properly, like if not call to twitter were done.
Here is my credential :

As you can see, data are nil, can you tell me have i don't do properly please ?

Thanks,

from swifter.

i did this to solve this problem:

if userHelper.fetchUserToken() != nil {
            self.swifter.client.credential = userHelper.fetchUserToken()
            user = self.userHelper.fetchUserQData()
        } else {
            self.swifter.authorizeWithCallbackURL(NSURL(string: "some.twitterapp://success")!, success: {
                credential, response in
                var tmp = self.swifter.client.credential?.accessToken?
                self.userHelper.saveUserToken(tmp!)

                },failure: failureHandler
            )
        }

func saveUserToken(data: SwifterCredential.OAuthAccessToken) -> Bool {

        var userdata = NSUserDefaults.standardUserDefaults()
        userdata.setObject(data.key, forKey: "key")
        userdata.setObject(data.secret, forKey: "secret")
        userdata.setObject(data.screenName, forKey: "screenName")
        userdata.setObject(data.userID, forKey: "userID")
        userdata.setObject(data.verifier, forKey: "verifier")
        userdata.synchronize()

        return true
    }

    func fetchUserToken() -> SwifterCredential? {
        var userdata = NSUserDefaults.standardUserDefaults()

        if var tkey = userdata.objectForKey("key") as? String {
            if var tsecret = userdata.objectForKey("secret") as? String {

                var access = SwifterCredential.OAuthAccessToken(key: tkey , secret: tsecret)
                return SwifterCredential(accessToken: access)
            }
        }
        return nil
    }

    func fetchUserQData() -> NSDictionary {
        var userdata = NSUserDefaults.standardUserDefaults()
        var data: NSMutableDictionary = NSMutableDictionary()
        data["screenName"] = userdata.objectForKey("screenName") as String?
        data["userID"] = userdata.objectForKey("userID") as String?
        return data
    }

i am sure, there are better ways to do that ;)

Hi Alex,

My question was not about how to save usertoken.

My problem is when i restart my app, how do i ask to twitter/swifter to refresh the token with my saved usertoken for dont have to login again anymore ?

Do you succeed to do this ?

from swifter.

i updated my answer above.

acaccount will stay nil.
i didn't get along with it,..

the others nil values are coming with the credentials i saved. so you can use these.

after authentication (twitter webpage) there is now need to login again, until you uninstall the app from your phone or simulator.

from swifter.

Ok Alex, and can you confirm that when you debug the user variable at this line :
user = self.userHelper.fetchUserQData()
You fetch exactly the same data as authorizeWithCallbackURL do please with your tmp var ?

As you can see in my debug picture, only the key and secret have data,

from swifter.

i had to add another piece of code. ;)

actually, you could just copy and paste the code. it will do a couple of steps to get the data and save it for all coming requests, incl authentication call if neccessary.

from swifter.

Thanks for your code ;)

So you confirm that :

var access = SwifterCredential.OAuthAccessToken(key: tkey , secret: tsecret)
return SwifterCredential(accessToken: access)

Does'nt return the fully object whith screenName and userID ? Its not normal isn't it ?

from swifter.

i do not really know if its normal - to be honest i expected this data, too ;) - but during debugging it shows, i need to do a request to get it....

from swifter.

Ok, i will continu to investigate. Thanks for you help !

It's been over an year since the last update of this issue: I believe the school's project is done by now :)
