如果选择电影，则委托事件didFinishPickingMediaWithInfo未被调用？

Question

我想使用UIImagePickerController。如果我从PhotoLibrary中选择一张图片，一切正常，调用方法didFinishPickingMediaWithInfo。但如果我选择一部电影，电影就会打开。如果我选择“选择”按钮，则该方法未被调用。谁能帮我？我使用Xcode 4.0.2和iOS 4.3.2

谢谢

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    if([[info objectForKey:@"UIImagePickerControllerMediaType"] isEqualToString:@"public.movie"]){
        //something code
        [self dismissModalViewControllerAnimated:YES];
    }
}
