带有“（""）”的JSON括号不等于“[”] "]" [英] JSON with "(" ")" brackets istead of "[" "]"

问题描述

in .m：

   @implementation ViewController
    {
    NSDictionary *_json;
}

- (void)viewDidLoad
{
    [super viewDidLoad];


    NSURL* url = [NSURL URLWithString:@"http://api.worldweatheronline.com/free/v1/weather.ashx?q=Si%C3%B3fok&format=json&num_of_days=5&key=mykey"];

    NSData *jsonData = [NSData dataWithContentsOfURL:url];

    NSError *error;
    _json = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

    NSDictionary* fullDictFromjson = _json[@"data"];

    NSLog(@"%@",fullDictFromjson);

    NSDictionary* currentCondition = fullDictFromjson[@"current_condition"];

    NSLog(@"%@",currentCondition);

之后我在Console（currentCondition）中得到了这个：

After this I got this in Console ( currentCondition ):

2013-04-18 22:18:16.758 weather[18111:c07] (
        {
        cloudcover = 0;
        humidity = 74;
        "observation_time" = "08:18 PM";
        precipMM = "0.0";
        pressure = 1019;
        "temp_C" = 11;
        "temp_F" = 51;
        visibility = 10;
        weatherCode = 113;
        weatherDesc =         (
                        {
                value = Clear;
            }
        );
        weatherIconUrl =         (
                        {
                value = "http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0008_clear_sky_night.png";
            }
        );
        winddir16Point = S;
        winddirDegree = 170;
        windspeedKmph = 5;
        windspeedMiles = 3;
    }
)

我无法解决这个问题。

And I can t work with this.

如果我在safari中打开此网址：

If I open this url in safari:

current_condition：[{cloudcover：0 ，......所以有[不是（

"current_condition": [ {"cloudcover": "0", ..... So there is "[" not "("

所以我的json错了，在xcode中

So my json is wrong, in xcode

我该怎么办？

推荐答案

您在日志输出中看到的只是集合的格式 NSArray 和 NSDictionary 对象，而不是实际的JSON本身。哪里有 [和日志语句中的（，你有一个数组;其中有一个 {你有一本字典。

What you are seeing in your log output is just the formatting of a collection of NSArray and NSDictionary objects, not the actual JSON itself. Where there's a [ in the source JSON and a ( in your log statements, you have an array; where there's a { you have a dictionary.

所以你需要从单元素数组中提取字典才能使用它：

So you need to extract the dictionary from the single-element array before you can use it:

NSDictionary* currentCondition = fullDictFromjson[@"current_condition"][0];
