获取Storyboard里面的单独控制器

第一步：要获取单独控制器所在的UIStoryboard
UIStoryboard *story = [UIStoryboard
storyboardWithName:@"Main"
bundle:nil];
第二步：获取该控制器的Identifier并赋给你的单独控制器
  YYJumpToShareViewController *vc = [story
instantiateViewControllerWithIdentifier:@"JumpToShareVC"];
    [self.navigationController
pushViewController:vc animated:YES];
