Question

我的JSON字符串是

"{\"CommentList\":[{\"SubmittedDate\":\"02/01/2017 06:09:32\",\"SubmittedTime\":\"\",\"UserId\":\"af0e1cda5c0\",\"UserName\":\"NepolionBon\",\"Comments\":\"\",\"Complete_Hour\":\"\",\"Complete_Minute\":\"\"}]}"

我需要＆＃34; SubmittedDate＆＃34;和＆＃34; Complete_Hour＆＃34;从它。

当我尝试使用

转换此字符串时

NSData *responseData = [responseString dataUsingEncoding:NSUTF8StringEncoding];

收到错误

 -[__NSSingleObjectArrayI dataUsingEncoding:]: unrecognized selector sent to instance 0x14decfc0

任何人都可以帮助我吗？

您可以使用此代码获取SubmittedDate和Complete_Hour。

NSString *jsonString = @"{\"CommentList\":[{\"SubmittedDate\":\"02/01/2017 06:09:32\",\"SubmittedTime\":\"\",\"UserId\":\"af0e1cda5c0\",\"UserName\":\"NepolionBon\",\"Comments\":\"\",\"Complete_Hour\":\"\",\"Complete_Minute\":\"\"}]}";

    NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
    id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

    NSArray* arrComments = [json objectForKey:@"CommentList"];

    for (NSDictionary *dict in arrComments) {
        NSLog(@"Submit date :%@",[dict objectForKey:@"SubmittedDate"]);
        NSLog(@"Comlplete Hour : %@",[dict objectForKey:@"Complete_Hour"]);

    }

- [__ NSSingleObjectArrayI dataUsingEncoding：]目标C.
