title: Facebook Graph API call not working in iOS application
body: <p>So I'm trying to write an iPhone application that allows a user to "Check-in" to a store using the Graph API method; something like</p>
  
  <pre><code>NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
  app_id, @"app_id",
  @"111664535537155", @"place",
  @"I just Checked Into A Retail Store", @"message", nil];
  
  [appDelegate.facebook requestWithGraphPath:@"me/checkins" andParams: params     andHttpMethod:@"POST" andDelegate:self];
  </code></pre>
  
  <p>but I'm having no luck. I know I've setup the rest of the Facebook Connect stuff fine, since my dialog calls such as </p>
  
  <pre><code>NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 app_id, @"app_id",
                                 @"Facebook Dialogs", @"name",
                                 @"Test Post", @"caption",
                                 @"Check out my Test Post", @"message",
                                 nil];
  
  
  [appDelegate.facebook dialog:@"feed" andParams:params andDelegate:self];
  </code></pre>
  
  <p>works fine.  According to <a href="http://www.raywenderlich.com/1488/how-to-use-facebooks-new-graph-api-from-your-iphone-app" rel="nofollow">This tutorial</a> Facebook Connect supports Graph API calls, and the authentication should be enough. </p>
  
  <p>Am I missing something? What should I try doing to fix this?  I've taken a look at the other related questions on Stack Overflow, but none of the solutions seems to solve my problem. </p>
  
  <p>Thanks</p>
