I have an app that I'm accessing a remote website with NSURLConnection to run some code and then save out some XML files. I am then accessing those XML Files and parsing through them for information. The process works fine except that my User Interface isn't getting updated properly. I want to keep the user updated through my UILabel. I'm trying to update the text by using setBottomBarToUpdating:. It works the first time when I set it to "Processing Please Wait..."; however, in the connectionDidFinishLoading: it doesn't update. I'm thinking my NSURLConnection is running on a separate thread and my attempt with the dispatch_get_main_queue to update on the main thread isn't working. How can I alter my code to resolve this? Thanks! [If I need to include more information/code just let me know!]

myFile.m

NSLog(@"Refreshing...");

dispatch_sync( dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
     [self getResponse:@"http://mylocation/path/to/file.aspx"];
});

[self setBottomBarToUpdating:@"Processing Please Wait..."];

queue = dispatch_queue_create("updateQueue", DISPATCH_QUEUE_CONCURRENT);

connectionDidFinishLoading:

if ([response rangeOfString:@"Complete"].location == NSNotFound]) {
  // failed
} else {
  //success
  dispatch_async(dispatch_get_main_queue(),^ {
       [self setBottomBarToUpdating:@"Updating Contacts..."];
  });

  [self updateFromXMLFile:@"http://thislocation.com/path/to/file.xml"];

  dispatch_async(dispatch_get_main_queue(),^ {
       [self setBottomBarToUpdating:@"Updating Emails..."];
  });

  [self updateFromXMLFile:@"http://thislocation.com/path/to/file2.xml"];  

}
