facebook connect not working - iphone

Question

This all is driving me nuts.
I just integrated facebook in my iphone app.
After typing in my username and password in the login dialog this method is called.
- (void)request:(FBRequest*)request didLoad:(id)result {
if ([request.method isEqualToString:#"facebook.fql.query"]) {
NSLog(#"result %#",result);
NSArray* users = result;
NSLog(#"users %#",users);
NSDictionary* user = [users objectAtIndex:0];
NSString* name = [user objectForKey:#"name"];
self.facebookName = name;
if (_posting) {
[self postToWall];
_posting = NO;
}
}
}
But after this the app crashes most of the times and when I tried to log the "result" array it appears to be empty. Why is it so?
What should I do? Please suggest.

Answer 1

use this code
NSArray *users=[[NSArray alloc]initWithObjects:result, nil];
NSLog(#"users %#",users);
NSDictionary* user = [[NSDictionary alloc]initWithObjectsAndKeys:users,#"users", nil];
NSLog(#"%#",user);

Answer 2

I got the reason for this.
This was due to the session getting lost frequently in between.
So I had to call [session resume] in the facebook login action event
and in this manner if at all the session is lost by any chance then the previous session is resumed and the "result" does not appears to be nil in (void)request:(FBRequest*)request didLoad:(id)result method.
Hope this helps out those who are stuck in the same issue.
