NSError* error = nil;
NSArray* jsonArray = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
if (jsonArray == nil) {
    NSLog(@"Error getting jsonArray: %@", error);
    // Handle error condition
}
NSArray* categoryArray = jsonArray[0];
for (NSString* innerJson in categoryArray) {
    NSData* innerJsonData = [innerJson dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary* innerDict = [[NSJSONSerialization JSONObjectWithData:innerJsonData options:0 error:&error];
    if (innerDict == nil) {
        NSLog(@"Error getting innerDict: %@", error);
        // Handle error condition
    }    
    NSString* category_id = innerDict[@"category_id"];
    // etc
}
// Repeat for subcategoryArray = jsonArray[1]
