Answer 1

you can reach numbers with two for loops:

for(NSArray *numbers in yourMainArray)
{
     for(NSNumber *n in numbers)
     {
         NSString *urlString = [NSString stringWithFormat:@"http://flicksbank.console360.net/images/%d/default.jpg", [n intValue]];
     }

}

or more general solution for NSString and NSNumber

    for(NSArray *numbers in yourMainArray)
    {
         for(id n in numbers)
         {
             if([n isKindOfClass:[NSNumber class]])
             {
                 NSString *urlString = [NSString stringWithFormat:@"http://flicksbank.console360.net/images/%d/default.jpg", [n intValue]];
             }
              if([n isKindOfClass:[NSString class]])
             {
                 NSString *urlString = [NSString stringWithFormat:@"http://flicksbank.console360.net/images/%@/default.jpg", n];
             }
         }

    }
