iphone - UIImagePickerController didFinishPickingMediaWithInfo not being called

I'm having trouble with using a UIImagePickerController. Basically, though the picker is being displayed fine, the UIImagePickerController didFinishPickingMediaWithInfo method is refusing to be called (I've tried NSLogging all the way through, it just doesn't get called). Here's my code (I've defined imgPicker in the header as an UIImagePickerController):

-(IBAction)grabImage {
    self.imgPicker = [[UIImagePickerController alloc] init];
    self.imgPicker.allowsImageEditing = YES;
    self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:self.imgPicker animated:YES];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    imgview.image = [info objectForKey:UIImagePickerControllerEditedImage];
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
}

Anyone have any idea as to why it isn't being called?

Have you set the delegate property of UIImagePickerController , if not do as below

myImagePickerController.delegate = self;

also confirm with the UIImagePickerControllerDelegate protocol,
