转换的NSString的NSDictionary在Objective-C

Posted 2021-04-07

这是我的字符串

     {
       ColorModel = RGB;
       DPIHeight = 72;
       DPIWidth = 72;
       Depth = 8;
       Orientation = 1;
       PixelHeight = 2848;
       PixelWidth = 4288;
       ProfileName = "Adobe RGB (1998)";
"{Exif}" =     {
       ColorSpace = 1;
       ComponentsConfiguration =         (
        1,
        2,
        3,
        0
    );
    DateTimeDigitized = "2011:03:12 16:17:25";
    DateTimeOriginal = "2011:03:12 16:17:25";
    ExifVersion =         (
        2,
        2
    );
    ExposureBiasValue = 0;
    ExposureProgram = 3;
    ExposureTime = "0.000625";
    FNumber = 4;
    Flash = 0;
    FlashPixVersion =         (
        1,
        0
    );
    FocalLength = 26;
    ISOSpeedRatings =         (
        200
    );
    LightSource = 14;
    MaxApertureValue = 4;
    MeteringMode = 5;
    PixelXDimension = 4288;
    PixelYDimension = 2848;
    SceneCaptureType = 0;
    SensingMethod = 2;
};
"{GPS}" =     {
    Latitude = "38.0374445";
    LatitudeRef = N;
    Longitude = "122.8031783333333";
    LongitudeRef = W;
};
"{IPTC}" =     {
    DateCreated = 20110312;
    DigitalCreationDate = 20110312;
    DigitalCreationTime = 161725;
    ObjectName = "DSC_0001";
    TimeCreated = 161725;
};
"{JFIF}" =     {
    DensityUnit = 1;
    JFIFVersion =         (
        1,
        0,
        1
    );
    XDensity = 72;
    YDensity = 72;
};
"{TIFF}" =     {
    DateTime = "2011:05:03 20:30:44";
    Make = "NIKON CORPORATION";
    Model = "NIKON D90";
    Orientation = 1;
    PhotometricInterpretation = 2;
    ResolutionUnit = 2;
    Software = "QuickTime 7.7.1";
    XResolution = 72;
    YResolution = 72;
};
}

我想用下面的代码把它转换成的NSDictionary

  NSData *myData = [myStr dataUsingEncoding:NSUTF8StringEncoding];
  NSDictionary *json = [NSJSONSerialization JSONObjectWithData:myData
                                                             options:kNilOptions
                                                               error:&err];

但要在末尾的空

我的事问题是串甲...我怎样才能改变我的字符串格式将其转换成的NSDictionary

编辑：得到这个错误

Error Domain=NSCocoaErrorDomain Code=3840 "No string key for value in object around character 6." UserInfo={NSDebugDescription=No string key for value in object around character 6.}

任何一个请？

答案

这不是JSON;它看起来更像是从[NSDictionary description]输出。

为了得到一些接近JSON，您需要：

• 将所有=字符:，提供name : value。
• 更改;元素之间,。
• 更改所有阵列分隔符从( ... )到[ ... ]。
• 添加双引号的所有非数值。

另一答案

尝试这个：

NSError *err = nil;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData: myData options: NSJSONReadingMutableContainers error: &err];
