title: Access Calendar Events GData in Objective C
body: <p>I was wondering if anyone knew how to access data from a google calendar in an objective c application. I am trying to create an iPhone application that access the data, process it and display it in a custom format. </p>
  
  <p>I have the sources in the project file and they are compiling fine, but I am having trouble actually getting the data. Can anyone lend me some help. Thanks a lot!</p>
  
  <p>UPDATE:</p>
  
  <p>Alright, I found a simple thing on google's website that gives a brief explanation of stuff, however when I go to use the code provided I get "SIGABRT"</p>
  
  <p>I do believe the error is lying in the didFinishSelector:@selector(ticket:finishedWithFeed:error:).</p>
  
  <p>In method to handle setting everything up.</p>
  
  <pre><code>ticket = [service fetchFeedWithURL:feedURL
                            delegate:self
                   didFinishSelector:@selector(ticket:finishedWithFeed:error:)];
  </code></pre>
  
  <p>The didFinishSelector method is as follows</p>
  
  <pre><code>- (void)ticket:(GDataServiceTicket *)ticket
   finishedWithFeed:(GDataFeedCalendar *)feed
       error:(NSError *)error {
  
  if (error == nil) {  
      NSArray *entries = [feed entries];
      if ([entries count] &gt; 0) {
  
          GDataEntryCalendar *firstCalendar = [entries objectAtIndex:0];
          GDataTextConstruct *titleTextConstruct = [firstCalendar title];
          NSString *title = [titleTextConstruct stringValue];
  
          NSLog(@"first calendar's title: %@", title);
      } else {
          NSLog(@"the user has no calendars");
      }
  } else {
      NSLog(@"fetch error: %@", error);
  }
  
  }
  </code></pre>
  
  <p>I get an error every time it tries to access this method. Does anyone have an idea why?</p>
