I am using UIImagePickerController to capture an image from camera. The app, which I am developing requires to read the metadata of the image just captured, especially its gps information. I am getting the metadata of the image from dictionary passed to the didFinishPickingMediaWithInfo method.
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = [info
objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
NSMutableDictionary *imgInfo = [info objectForKey:UIImagePickerControllerMediaMetadata];
NSLog(@"Image Metadata : %@",imgInfo);
//Passing the imgInfo to other methods for further processing.
}
}
But in the logs I noticed that the metadata does not contains the gps information of the image, also some of the EXIF data is missing when compared with a photo taken by the regular iOS camera.
Why the metadata returned by UIImagePickerController is different from the metadata of image taken by regular ios camera? And how can I get the complete metadata of the image including the gps information?
