我正在使用我拍摄的照片中的iPhone EXIF数据。
目前我收到的EXIF数据是:
{
ApertureValue = "2.970854";
ColorSpace = 1;
ComponentsConfiguration = (1,2,3,);
ExifVersion = (2,2,1);
ExposureMode = 0;
ExposureProgram = 2;
ExposureTime = "0.03333334";
FNumber = "2.8";
Flash = 16;
FlashPixVersion = (1,0);
FocalLength = "3.85";
ISOSpeedRatings = (500);
MeteringMode = 3;
PixelXDimension = 640;
PixelYDimension = 480;
SceneCaptureType = 0;
SensingMethod = 2;
Sharpness = 2;
ShutterSpeedValue = "4.911055";
SubjectArea = (319,239,230,172);
WhiteBalance = 0;
}
我希望能够添加一些字段,例如地理位置,日期和时间。 如何指定要返回的新密钥? 任何人都知道在ios 4.1中这是可能的吗?
