ios - CAPS 页面菜单 : willMoveToPage delegate method getting error

Question

我正在使用 UIPageMenuController。单击按钮时，我必须转到第 3 页。 我正在尝试调用 will willMoveToPage 委托(delegate)方法，出现错误

willMoveToPage:index:]: 无法识别的选择器发送到实例

在我的代码下面:

let storyBoard = UIStoryboard.init(name: "Main", bundle: nil)
        let yourVC = storyBoard.instantiateViewController(withIdentifier: "ProfileConnectionsController") as! ProfileConnectionsController
        pageMenu?.delegate?.willMoveToPage!(yourVC, index: 2)

Answer 1

错误显示 willMoveToPage:index:]: unrecognized selector sent to instance 你没有实现委托(delegate)方法

第一步

确保一旦你在你的类中实现委托(delegate)

class ViewController:UIViewController,CAPSPageMenuDelegate

并确保一旦您确认委托(delegate)

pageMenu.delegate=self

第二步

After that you will be able to set up the following delegate methods inside of your parent view controller

确保调用方法一次

func willMoveToPage(controller: UIViewController, index: Int) {
   if let getSubview=controller as! ProfileConnectionsController
   {
    getSubview.pageNumber=index
  }
}
