Question

Three days ago this code worked…:(

The label will not update to show the loaded facebook username.

//Interface .h
IBOutlet UILabel *namefb;  
...
@property(nonatomic, retain)UILabel *namefb;


//Implementation .m

- (void)request:(FBRequest*)request didLoad:(id)result {

        NSArray* users = result;

    NSDictionary* user = [users objectAtIndex:0];

    NSString* name = [user objectForKey:@"name"];

       namefb.text=[NSString stringWithFormat:@"Log-in: %@", name];//not update
}

(I have also connected the label in IB and imported all fbconnect delegates )

When I run it in debug, the variable name is right, but namefb.text does not get updated..

Any ideas?

sorry for my english..:)

Answer 1

Your code assumes three things:

1. The result object is of type NSArray.

2. The NSArray has at least one object, which is an NSDictionary.

3. That object has a key “name” that has an NSString object associated with it.

Test each of these three things, perhaps by using some NSLog() statements, and you should see where the problem is.
