Save Photo to App Directory |
This recipe shows how to save a photo to an application’s Documents directory. |

The sample code uses the Camera helper from TweetStation to take a picture, and then demonstrates how to save it in the completion handler. The photo is saved to the applications Documents directory, like this:
TweetStation.Camera.TakePicture (this, (obj) =>{
var photo = obj.ValueForKey(new NSString("UIImagePickerControllerOriginalImage")) as UIImage;
var documentsDirectory = Environment.GetFolderPath
(Environment.SpecialFolder.Personal);
string jpgFilename = System.IO.Path.Combine (documentsDirectory, "Photo.jpg"); // hardcoded filename, overwritten each time
NSData imgData = photo.AsJPEG();
NSError err = null;
if (imgData.Save(jpgFilename, false, out err)) {
Console.WriteLine("saved as " + jpgFilename);
} else {
Console.WriteLine("NOT saved as " + jpgFilename + " because" + err.LocalizedDescription);
}
});
Saving the image data in this way does NOT include the metadata supplied by the camera (such as GPS location, camera model, exposure, etc).
