私は次のコードを持っています:
SecondViewController *secondView = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setCameraOverlayView:secondView.view];
[imagePicker setShowsCameraControls:NO];
[self presentModalViewController:imagePicker animated:YES];
私の質問は、「SecondViewController」からModalViewControllerを閉じるにはどうすればよいですか?
