，我所面臨的問題，這個（很長的）JSON文件是，我有很多次的JSON對象 我寫的此功能來解析該文件
-(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];
}
}
}
}
此功能在這裏給我一個例外：
NSDictionary *contacts=[clients objectForKey:@"contacts"];
我是新來這個 感謝您的幫助和耐心
你能否正確地格式化你的問題。這太瘋狂了，甚至不能自己開始做。 – Popeye 2013-04-23 11:27:36
這只是普通的'JSON - 沒什麼特別的。你一次「剝離」一層，就像洋蔥一樣。你的問題是「客戶」是一個數組（2個元素），而不是字典。使用在線格式化程序[this one]（http://json.parser.online.fr/）「JSON打印」JSON，並在每個圖層中使用NSLog來檢查您的內容。 （請注意，NSLog用'（）'替換'[]'） – 2013-04-23 11:27:59
@Popeye - 使用在線格式化程序 - 它總比在SO窗口中嘗試閱讀JSON要好。 – 2013-04-23 11:28:35
