检索JSON数据作为NSString而不是整数

Question

下面的代码仅适用于我的JSON数据是一系列整数，例如[11,12,13]。我怎么能让它检索消息/短语代替?

- (IBAction)checkmessages:(id)sender
{
        responseData = [[NSMutableData data] retain];       
        NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"file:///Users/Alex/Desktop/Test.json"]];
        [[NSURLConnection alloc] initWithRequest:request delegate:self];
    }
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {      
    [connection release];
    NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
    [responseData release];
    NSError *error;
    SBJSON *json = [[SBJSON new] autorelease];
    NSArray *luckyNumbers = [json objectWithString:responseString error:&error];
    [responseString release];   
    if (luckyNumbers == nil)
        label.text = [NSString stringWithFormat:@"JSON parsing failed: %@", [error localizedDescription]];
    else {      
        NSMutableString *text = [NSMutableString stringWithString:@"Latest Message:n"];
        for (int i = 0; i < [luckyNumbers count]; i++) 
            [text appendFormat:@"%@n", [luckyNumbers objectAtIndex:i]];
        label.text =  text;
    }
}

编辑:当我的JSON文件看起来像:[10,11,12]，它工作得很好，但如果我把它改为:[消息1，消息2]，我得到错误:"JSON解析失败:解析数组时的期望值"

Answer 1

你的JSON看起来有问题，

 [Message 1,Message 2]

应该

 ["Message 1", "Message 2"]

Answer 2

JSON中的"Strings"必须用引号括起来("")
