Can you pre-fill the text to post to your wall, might integrate Share with Facebook with Snippety

yeah, everything in a message can be changed/added from the code, download the project and write something on my wall.
I understand that some of your friends can be offended that you test your app on their walls in facebook, but feel free to test it on mine

What should I modify in order to write only on my wall a sentence coming from a variable?

Thanks

Hi Sunny:

Do you know why when I get the friend list, the spanish characters like "ñ", "é", "ó", and so on, don't appear properly?

by **sunny** » Mon Jan 18, 2010 8:30 pm

did you specify <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> in <head> section?

by **lmarcogimenez** » Mon Jan 18, 2010 8:34 pm

Yes, I've tried with utf-8 and iso-8859-1, both of them with the same result.

found what is the problem, it's JSON encoder does not encode unicode symbols properly :-\
will fix that in next release, for now you can pass the strings from obj-c (will be even better then whole array as the list of friends will fill one by one rather then wait for long time and get whole list)
here how it can be, replace 'else if' block with this code on 169 line of code:

Code: Select all

      else if ([request.userInfo isEqualToString:@"friend_name_request"])
      {
         NSDictionary* person = [result objectAtIndex:0];
         [self._webView performSelectorOnMainThread:@selector(stringByEvaluatingJavaScriptFromString:) withObject:[NSString stringWithFormat:@"newFriendAdded('%@', '%@')", [person objectForKey:@"name"], [person objectForKey:@"uid"]] waitUntilDone:NO];
      }

and remove this on 50 line of code

Code: Select all

while (_requestInProgress) {
      [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.5]]; // wait for request to complete or fail
   }

and remove on 46 line

Code: Select all

_requestInProgress = YES;

also you will need to modify main.html file to obtain not array but having callback function newFriendAdded(name, uid) and remove &sync=yes from CallNKitAction("getFriendsList?className=AppFBController");
I attach working example here

Great Sunny!

Progressive friend list loading is better to avoid long time delay, but I would like to put in the page an activityIndicator to inform the user that some friends are not loaded yet. Is it possible to know when the list is completed?

yep, else if section on line 167 should be:

Code: Select all

      else if ([request.userInfo isEqualToString:@"friend_name_request"])
      {
         NSDictionary* person = [result objectAtIndex:0];
         [self._webView performSelectorOnMainThread:@selector(stringByEvaluatingJavaScriptFromString:) withObject:[NSString stringWithFormat:@"newFriendAdded('%@', '%@')", [person objectForKey:@"name"], [person objectForKey:@"uid"]] waitUntilDone:NO];
         if (--_uidsCount == 0)
         {
            // here it is loaded, we can call function to stop indicator
            [self._webView performSelectorOnMainThread:@selector(stringByEvaluatingJavaScriptFromString:) withObject:@"stopFriendsLoadingIndicator()" waitUntilDone:NO];
         }
      }
