    text
    copied!<p>I'm trying to use Facebook's Graph API to retrieve a list of checkins for myself from an iPhone application. I've requested a token and am able to access my profile information and a list of my friends, but when I request checkins I always get back an empty record set. I'm guessing it has something to do with the permissions I'm requesting, but I can do the query with the same permission on the Facebook Graph API Explorer (<a href="https://developers.facebook.com/tools/explorer?method=GET&amp;path=me%2Fcheckins" rel="nofollow">https://developers.facebook.com/tools/explorer?method=GET&amp;path=me%2Fcheckins</a>) and I do get data.</p> <p>Token request:</p> <pre><code>NSArray *perm = [NSArray arrayWithObjects: @"user_status", @"user_events", @"user_location", @"friends_checkins", @"friends_status", nil]; [FBSession openActiveSessionWithReadPermissions:perm allowLoginUI:YES completionHandler: ^(FBSession *session, FBSessionState state, NSError *error) { //handle the session opening }]; </code></pre> <p>Then when I try to retrieve the checkins (in seperate view controller):</p> <pre><code>[[FBRequest requestForGraphPath:@"/me/checkins"] startWithCompletionHandler: ^(FBRequestConnection *connection, NSDictionary&lt;FBGraphObject&gt; *checkins, NSError *error) { if (!error) { NSLog(FBSession.activeSession.description); NSArray *data = [checkins objectForKey:@"data"]; for (FBGraphObject *c in data) { //execution never gets here because data is empty } } }]; </code></pre> <p>The execution never reaches the <code>for</code> loop because the <code>data</code> variable is empty.</p> <p>I've printed out the current session state just before the <code>for</code> loop to ensure that everything is correct. the result was:</p> <pre><code>&lt;FBSession: 0x15555555, state: FBSessionStateOpen, loginHandler: 0x5555555, appID: 55555555555, urlSchemeSuffix: , tokenCachingStrategy:&lt;FBSessionTokenCachingStrategy: 0x15555555&gt;, expirationDate: 4001-01-01 00:00:00 +0000, refreshDate: 2013-05-15 06:55:56 +0000, attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:( "user_status", "user_events", "user_location", "friends_checkins", "friends_status" )&gt; </code></pre> <p>I can't figure out what I might be missing.</p>
