我为我的应用程序和界面构建器中的所有视图控制器创建了一个IBOutlet,我将插座连接到适当的控制器.每个控制器也加载适当的XIB,所以这都不是问题所在.问题是以下更改视图代码.

这是我的代码：

-(void)changeViews {
    CGRect frame = self.view.frame;
    frame.origin.x = CGRectGetMaxX(framE);
    theView4.view.frame = frame;

    [self.view addSubview:theView4.view];
    [self addChildViewController:theView4];

    [self transitionFromViewController:theView1 
                      toViewController:theView4 
                              duration:1 
                               options:UIViewAnimationOptionTransitionNone
                            animations: ^{
                                CGRect frame = self.view.frame;
                                theView4.view.frame = frame;
                                frame.origin.x -= frame.size.width;
                                self.view.frame = frame;
                            }
                            completion:completion:nil];

这是控制台崩溃：

*** TerminaTing app due to uncaught exception 'NSInvalidArgumentexception',reason: 'Children view controllers <MyGameViewController: 0x1dd25210> and <SetTings: 0x1dd249d0> must have a common parent view controller when calling -[UIViewController transitionFromViewController:toViewController:duration:options:animations:completion:]'

有谁知道如何解决这一问题？

谢谢！
