Question

First i create facebook object with my appId:

facebook = [[Facebook alloc] initWithAppId:kAppId];

When i call

[_facebook authorize:_permissions delegate:self] 

my safari opens up and after i enter my FB username and password, safari closes and everything returns to my app (like it should).
My permissions are:

_permissions =  [[NSArray arrayWithObjects:@"read_stream", @"publish_stream", @"offline_access",nil] retain];

The strange thing is that my delegate method – (void)fbDidLogin or -(void)fbDidNotLogin:(BOOL)cancelled is not called like in FB sample app that comes with SDK. In my .h file i implement protocols “FBRequestDelegate,
FBDialogDelegate, FBSessionDelegate” and in .m file i have the necessary methods.

If i try to make a post after that with

[_facebook requestWithGraphPath:@"me/feed" 
        andParams:[NSMutableDictionary dictionaryWithObject:@"test wall post" forKey:@"message"]
                  andHttpMethod:@"POST"
                    andDelegate:self];

i get error “req failed with error The operation couldn’t be completed. (facebookErrDomain error 10000.)”. This must be something related to authorization, but since i get no message after authorize call, i don’t know that to do.

Any ideas?

NSMutableDictionary *params = [NSMutableDictionary  dictionaryWithObjectsAndKeys:
                      @"My new status message", @"message",
                      nil];
[_facebook requestWithGraphPath:@"/me/feed"
                  andParams:params
                  andHttpMethod:@"POST"
            andDelegate:self];

or

The error object returned has the details about what’s happening.
I suggest to implement that method to get more infos:

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error {
    NSLog(@"%@", [error localizedDescription]);
    NSLog(@"Err details: %@", [error description]);
};

For example for my problem gived me that info, and I’ve fixed it:

2011-05-27 11:19:57.313 Challengein[7704:207] The operation couldn’t be completed. (facebookErrDomain error 10000.)
2011-05-27 11:19:57.314 Challengein[7704:207] Err details: Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0x6878b90 {error=<CFBasicHash 0x6879be0 [0x141c400]>{type = mutable dict, count = 2,

}
}
