Question

I want to get the timestamp when the image is captured in my application. Do we have any notification when the camera is clicked?

Answer 1

use UIImagePickerController delegate:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    NSDictionary *metadataDictionary = (NSDictionary *)[info valueForKey:UIImagePickerControllerMediaMetadata];
        // do something with the metadata

    NSLog(@"meta : %@ \n\n",metadataDictionary);
}
