Question

Request:

- (void) getMyImageWithContestOfFace{
currentApiCall = getMyImageFb;
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"SELECT pic FROM user WHERE uid=me()",@"query",
                               nil];
AppDelegate *delegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];
[[delegate facebook] requestWithMethodName:@"fql.query"
                                 andParams:params
                             andHttpMethod:@"POST"
                               andDelegate:self];
}

Parsing:

...
case getMyImageFb:{
        flag = TRUE;
         imageWithFace = [[UIImage alloc] init];
         imageWithFace = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[result objectForKey:@"pic"]]]];
        }
        break;
...

When i call it i catch very strange exeption:

*2011-11-10 00:30:30.661 FaceGraph[1699:f803] I have some information
2011-11-10 00:30:30.664 FaceGraph[1699:f803] -[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0x6d3d470

terminate called throwing an exceptionsharedlibrary apply-load-rules all
Current language: auto; currently objective-c

No idea why. The most strange that i did it before ABSOLUTELY the same, and it worked fine.
I can’t find the difference between my old projects and current. Maybe somebody have the same problem?? If you need more code – ask for it.

thanks

Well, the exception seems to be quite clear: result is probably an array and not a dictionary.

PS: The line imageWithFace = [[UIImage alloc] init]; is totally superfluous given the line that follows it. You should remove it.
