iOS beginner here. I have the following code:
[facebook authorize:nil delegate:self]; NSString *string1=[facebook accessToken]; NSLog(string1);
The log shows: miFOG1WS_7DL88g6d95Uxmzz7GCShsWx_FHuvZkmW0E.eyJpdiI6IjNZZkFBY1c5ZnBaMGEzOWM2RzNKbEEifQ.LNjl06lsOQCO9ArVARqff3Ur2XQHku3CMHDBKkpGg351EB33LGxVv96Hh5R860KDJL0cLq8QezSW0GovYxnhUucOwxlITV364sVKDXIzC3bAn9P_74r2Axl1SgOaTyMMkQ_aSQ2OWh-8d3Zn9BDt3pXVWzBLJ9I4XAosnw0GjuE
This seems too long to be an access token. I read it's supposed to be only 40 characters long. What am I doing wrong?
Go to https://developers.facebook.com/tools/explorer/ and select your app from the first drop down menu, in the left. Click on the button "Get access token", and in the "Select Permissions" window, click in "Extended Permissions" and check manage_pages and publish_stream, and click in "Get Access Token" blue button.
Using v3.2.1 as of March 20, 2013 of Facebook SDK.
NSString *fbAccessToken = [[[FBSession activeSession] accessTokenData] accessToken];
If you prefer dot syntax,
NSString *fbAccessToken = [FBSession activeSession].accessTokenData.accessToken;
For those using Swift;
var fbAccessToken = FBSession.activeSession().accessTokenData.accessToken
Update for v4.1.0 SDK onwards
Objective-C
NSString *fbAccessToken = [FBSDKAccessToken currentAccessToken].tokenString;
Swift
var fbAccessToken = FBSDKAccessToken.currentAccessToken().tokenString
