Question

我有一个JSON的String格式

 {
    abstract = "Today P.M of India Mr. Narender Modi visited for the eve of Agarasen \njayanti
\n";
    created = 1444733102;
    imgUrl = "";
    nid = 12;
    title = "Latest news";
}

我想转换为NSDictionary

NSError *jsonError;
NSData *objectData = [[[tableDataArray objectAtIndex:indexPath.row]objectForKey:@"NewsValue"] dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&jsonError];
NSLog(@"%@",json);

他们回答是空的请帮助。

Answer 1

这已经存在于字典格式的Json数据中。

所以你不需要转换。只需检索数据。

NSString * abstract = [Dic valueForKey:@"abstract"];

Answer 2

请使用以下代码

NSData * objectData = [[[tableDataArray objectAtIndex：indexPath.row] objectForKey：@＆＃34; NewsValue＆＃34;] NSString * strResponce = [[NSString alloc] objectData encoding：NSUTF8StringEncoding];

NSMutableDictionary *dictResponse = [NSJSONSerialization JSONObjectWithData:[strResponce dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:&error];

if（[dictResponse isKindOfClass：[NSMutableDictionary class]]）{

NSString * abstractStr = [dictResponse valueForKey：@＆＃34; abstract＆＃34;];

}

字符串转换为字典
