从UIPageViewController的根视图控制器执行Segue

Question

我有一个UIPageViewController并在其中有一个按钮。无论何时按下按钮，我想从父视图控制器（其中嵌入导航控制器）执行Segue到导航堆栈中的下一个视图控制器。我也希望能够通过segue传递数据。我尝试了几件事，但我对iOS开发非常陌生，一直都没有成功。

您需要选择故事板中的segue，并为其指定一个唯一的标识符并将其放在下面的代码中。

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ 

if ([segue.identifier isEqualToString:@"YourSegueIdentifier"]) { 
    // get a reference to the destination View Controller 
    UIViewController *destinationVC = [segue destinationViewController]; 
    XXYourViewControllerSubclass *yourVC = (XXYourViewControllerSubclass*)destinationVC; 
    // create the data and pass it to the view controller 
    id someData = // create your data (unless you have a property holding it already) 
    [yourVC acceptData:(id)someData]; // make a public method on your VC subclass to accept the data 
} 
// after this method has returned the seque will be performed 
} 

这有道理吗？
