Проблема, с которой я столкнулся в том, что у меня есть много суб JSON объектов я написал эта функция разобрать этот файл
-(void)readJson
{
//Emplacement du json file
NSString *filePath = [[NSBundle mainBundle]pathForResource:@"allClients?userId=2" ofType:@"json"];
//Contenu du fichier
NSString *jsonString = [NSString stringWithContentsOfFile:filePath];
NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&error];
id wordParam = [[json objectForKey:@"words"] objectForKey:@"word"];
if ([wordParam isKindOfClass:[NSArray class]]) {
NSDictionary *word = [(NSArray *)wordParam objectAtIndex:0];
} else if ([wordParam isKindOfClass:[NSDictionary class]]) {
NSDictionary *word = (NSDictionary *)wordParam;
} else {
NSLog(@"error. %@ is not an array or dictionary", wordParam);
}
//_data
NSDictionary *items = [json objectForKey:@"_data"];
for (NSDictionary *item in items)
{
NSDictionary *clients = [items objectForKey:@"clients"];
for(NSDictionary *client in clients)
{
NSString * clientId=[client objectForKey:@"id"];
NSString * name=[client objectForKey:@"name"];
@try{
NSDictionary *contacts=[clients objectForKey:@"contacts"];
}
@catch (NSException *ex) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"%@",ex]
delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
}
}
}
}
Эта функция является давая мне исключение здесь:
NSDictionary *contacts=[clients objectForKey:@"contacts"];
Я новичок в этом Спасибо за вашу помощь и терпение
Не могли бы вы правильно откорректировать ваш вопрос. Это слишком сумасшедший, чтобы даже начать делать это сам. – Popeye
Это просто простой «JSON» - ничего особенного. Вы «очищаете» один слой за раз, как лук. Ваша проблема в том, что «клиенты» представляют собой массив (из 2 элементов), а не словарь. «Достаточно напечатать» JSON с помощью онлайн-форматирования, такого как [этот] (http://json.parser.online.fr/), и использовать NSLog с каждым слоем, чтобы изучить, что у вас есть. (Просто имейте в виду, что NSLog заменяет '[]' на '()'.) –
@Popeye - использовать онлайн-форматирование - это лучше, чем пытаться читать JSON в SO-окне в любом случае. –
