objective-c - 我可以使用以下方法作为 IBAction

Question

我可以将以下功能用作 IBAction - 单击按钮吗？如果是，请告诉我如何...

-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController
      viewControllerAfterViewController:(UIViewController *)viewController

-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController 
     viewControllerBeforeViewController:(UIViewController *)viewController

Answer 1

No, you can't.

IBAction is actually equal to void -> only void returning methods can be connected.

IBOutlet and IBAction

Also the methods you are referring to are implementing the UIPageViewControllerDataSource, therefore a UIPageViewController should call them, but never you, see Delegates and Data Sources.
