No results returned when doing Facebook Query - objective-c

I'm trying to get a list of aid (album ids) using a Facebook Query.
What Works:
Running the query from the browser returns results, but when I run it using Facebook Connect no values are returned.
The problem I'm having is specific the album object, I get results when querying the user table.
The only real difference I can think of is when running from the browser a access_token parameter is included, running from browser without this returns nothing.
Authentication:
I am using OAuth to authenticate as outlined here: Mobile Apps - Getting Started
Do I need to include the access_token in the parameter list when doing a query?
The Code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
facebook = [[Facebook alloc] initWithAppId:#"<myAppId>"];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:#"FBAccessTokenKey"]
&& [defaults objectForKey:#"FBExpirationDateKey"]) {
facebook.accessToken = [defaults objectForKey:#"FBAccessTokenKey"];
facebook.expirationDate = [defaults objectForKey:#"FBExpirationDateKey"];
}
if (![facebook isSessionValid]) {
[facebook authorize:nil delegate:self];
}
NSArray* permissions = [[NSArray arrayWithObjects:
#"email", #"read_stream", nil] retain];
[facebook authorize:permissions delegate:self];
NSString *fql = [NSString stringWithFormat:#"SELECT aid FROM album WHERE owner=me()"];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:fql, #"query", #"json", #"format", nil];
[facebook requestWithMethodName:#"fql.query" andParams:params andHttpMethod:#"GET" andDelegate:self];
return YES;
}
- (void)request:(FBRequest *)request didLoad:(id)result {
if ([result isKindOfClass:[NSArray class]]) {
result = [result objectAtIndex:0]; }
NSLog(#"didLoad() received result: %#", result);
}

Yes, you absolutely need to include the access_token field. We verify that the access token has access to the user_photos permission before allowing you access to that user's data.

UIWebview does not start loading

I'm developing a native application for a website. The application is basically a wrapper around the website, which implements things like push notifications. When a push notification is clicked, the following code is used to go to the appropriate page:
- (NSString *)handlePush:(NSDictionary *)notification
{
if ([[notification objectForKey:#"aps"] objectForKey:#"badge"]) {
int badgeNum = [[[notification objectForKey:#"aps"] objectForKey:#"badge"] integerValue];
NSLog(#"Badge: %i, got from %#", badgeNum, [[notification objectForKey:#"aps"] objectForKey:#"badge"]);
[UIApplication sharedApplication].applicationIconBadgeNumber = badgeNum;
}
if (!active) {
NSLog(#"Got noti while not active, going to that chat!");
NSString *hash;
if ((hash = [notification objectForKey:#"h"])) {
NSLog(#"Hash: %#", [hash stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]);
return [NSString stringWithFormat:#"#%#", hash];
}
return #"";
}
return nil;
}
Active is changed when the application enters the background and after it resumes, to make sure it does not trigger when a push notification arrives when the user is using the app.
The URL is parsed properly, because if i manually paste the exact same URL in the browser, i do go to the correct page.
I am 100% certain the delegate is set, as the UIWebView: ShouldStartLoadWithRequest method is called:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *url = [[request URL] absoluteString];
NSLog(#"shouldStartLoadWithRequest called with url %#", url);
if ([url hasPrefix:BASE_URL]) {
NSLog(#"Yea, i'll load this one for ya");
// remove any get-params / hash suffix
NSRange r = [url rangeOfString:#"?"];
if (r.location == NSNotFound)
r = [url rangeOfString:#"#"];
if (r.location != NSNotFound)
url = [url substringToIndex:r.location];
if (![url isEqualToString:[defaults valueForKey:#"baseUrl"]]) {
NSLog(#"setting new baseUrl %#", url);
[defaults setValue:url forKey:#"baseUrl"];
[defaults synchronize];
}
NSLog(#"Should go and load it now...");
return YES;
}
}
There's some logic for caching versions of the webpage in there. I stepped through with breakpoints, and it reaches the return YES part, and the logs in there are called. However, in that same delegate, the didStartLoad and didFailLoadWithError are not called, which contain purely NSLogs.
On the initial application start, this does work, and it has worded one time too where i stepped through for a long time using the breakpoint, so it seems it's some timing issue. Hoping not having to use any hacky solutions like timers, i was hoping that anyone around here has experience with a similar problem, or has any other valuable input.

FBConnect iOS SDK publish_action Issue

I must say I feel like an idiot right now. :) I've been up and down Facebook, Google and StackOverflow and still cannot get the answer to what I am doing wrong! :) I've looked at both Facebook examples: Hackbook and WishList. Wishlist is obviously the one that should tell me what to do, but ALL the examples I've seen have the OBJECT part as a URL. I do not necessarily desire this, as I just want the post to say (this user) is playing [MyGame].
Ok here's my goal. I have an iPhone game. I want to do what Spotify does when you listen to a song, which posts to timeline and ticker. I'd also like to use this to post the player's score on the user's timeline and ticker.
I setup Open Graph with an action called Play and an object called Game along with it's aggregator. I think I also will need an action called Score?
Anyways, I can successfully post to a user's wall using feed dialog, but that's not what I want for the Play action.
Here's a concise version of what I got so far, any help is much appreciated:
Couple Notes:
I have a singleton FacebookInfo which takes care of handling Facebook delegates and stuff. I also have a FacebookUser class which hold the current user's info for the current session, populated when calling me. I also have a DLog method which simply does an NSlog only on debug mode.
When a user clicks the Play button in my game, I would like to call my method [[Facebook sharedInfo] publishAction:#"play"] below. I'm passing an NSString as action so later I can call the same method and use an action like Score and just modify the post accordingly.

Wow, I know this is a long post, but I hope someone can help point me in the right direction.
UPDATE 1: (2012/18/02)
Ok. So I settled for making a page which contains the og meta-data which I did not want to do and supplied the url for my object. As per the FB Documentation, found here:
Open Graph Mechanics
When users take an action in your app, such as cook the Stuffed Cookie, the app calls a Graph API to create a new cook action that connects the user with the Stuffed Cookie object. This is accomplished by issuing a HTTP POST to the user’s /me/myapp:cook connection with the URL of the recipe object. Facebook will then crawl the object URL, read the metadata, and connect the object to user's Graph via the action.
The diagram below illustrates the process:
User takes an action in the app, such as "cook" a "recipe"
App calls a Graph API /me/action:object=Object_URL
Facebook will crawl the object URL, read its meta tags and connects the object to the user's Graph via the action.
It would be cool if we can define these things in the app itself as params for cases where I do not need a website for.
As of 4/21/12 Facebook requires you to have created a page to get the data desired.

Post to the users Facebook wall from an iOS app

I know this has been asked a lot here, but none of the answers seem to work for me :(
I'm trying to post text to the users Facebook wall from my iPhone app. I already have the Facebook delveloper stuff set up, and almost everything is working. Almost.
facebook = [[Facebook alloc] initWithAppId:#"123813234381280"];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:#"FBAccessTokenKey"]
&& [defaults objectForKey:#"FBExpirationDateKey"]) {
facebook.accessToken = [defaults objectForKey:#"FBAccessTokenKey"];
facebook.expirationDate = [defaults objectForKey:#"FBExpirationDateKey"];
}
if (![facebook isSessionValid]) {
NSArray* permissions = [[NSArray arrayWithObjects:
#"publish_stream", nil] retain];
[facebook authorize:permissions delegate:self];
}
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"123813234381280", #"app_id",
#"http://test.com/", #"link",
#"Test-Name", #"name",
//#"Reference Documentation", #"caption",
#"Download the app NOW from the App Store", #"description",
#"Test-Message", #"message",
nil];
[facebook dialog:#"feed" andParams:params andDelegate:self];
Now there appears a dialog, but the textfield where it should say "Test-Message" in it is empty. You know, the one where it says what to post on the wall. Everything else works, the description, the link, the name. Everything besides the message.
Can anybody help me?
Facebook is now ignoring the message parameter:
http://developers.facebook.com/blog/post/510/
message : This field will be ignored on July 12, 2011 The message to
prefill the text field that the user will type in. To be compliant
with Facebook Platform Policies, your application may only set this
field if the user manually generated the content earlier in the
workflow. Most applications should not set this.

iOS Facebook Connect news feed

I need to get the user news feed data.
Currently I'm using this:
[[FBManager defaultManager]getFBRequestWithGraphPath:#"me/home" params: andDelegate:self];
and then:
- (void)request:(FBRequest *)request didLoad:(id)result {
if ([result isKindOfClass:[NSArray class]])
result = [result objectAtIndex:0];}
result gives me a bunch of data. But how do Extract these individually? Maybe the name and message for example??
I'd change from using requestWithGraphPath to requestWithMethodName.
Here's the sample code:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
[NSString stringWithFormat:#"SELECT post_id, actor_id, message FROM stream WHERE filter_key = 'others '", #"query",
nil];
[facebook requestWithMethodName: #"fql.query"
andParams: params
andHttpMethod: #"POST"
andDelegate: self];
Then in the request didLoad method:
- (void)request:(FBRequest *)request didLoad:(id)result
{
if ([result isKindOfClass:[NSArray class]])
result = [result objectAtIndex:0];
friendID = [[result objectForKey:#"actor_id"]copy];
friendMsg = [[result objectForKey:#"message"]copy];
}
Facebook documentations on the iOS FB Connect SDK are very blend. It helps if you know a bit of SQL(fql) :)

}
dialog.userMessagePrompt = #"Enter anything about the item here:";
[dialog show];
}
What could be wrong?
not sure why you should have a array of delegate...
if stuck, try the old API:
facebook = [[Facebook alloc] initWithAppId:#"YOUR_APP_ID"];
[facebook dialog:#"stream.publish" andParams:fbArguments andDelegate:self];
easier, faster (for prototyping or light needs.
if you want a specific answer to your issue, please provide more details (where do you initialize your fb object, where do you call FBSession from).
