So, when you parse that, you will have a NSDictionary with for which the first two keys have a value which is an NSArray:
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (error)
NSLog(@"JSONObjectWithData error: %@", error);
NSArray *array = dictionary[@"22398f2"];
NSString *firstArrayItem = array[0]; // @"CBW32"
NSString *secondArrayItem = array[1]; // @50.1083
Or, if you want all of the first items, you could do something like:
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (error)
NSLog(@"JSONObjectWithData error: %@", error);
[dictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
NSArray *array = obj;
if ([obj isKindOfClass:[NSArray class]])
NSLog(@"first item = %@", array[0]);
else
NSLog(@"The value associated with key '%@' is not array", key);
}];
