从一个类调用IBOutlet UIButton到另一个Viewcontroller [英] call IBOutlet UIButton from one class to another Viewcontroller

问题描述

我有一个名为dataviewcontroller的视图控制器.另一种名为scopeviewcontroller

I have one view controller called dataviewcontroller.Another view controller called scopeviewcontroller

在dataviewcontroller中，我有一个UIButton的IBOutlet称为AddData.我想在我的scopeviewcontroller中调用此按钮.我想隐藏该按钮.

In dataviewcontroller i have an IBOutlet of UIButton called AddData.I want to call this button in my scopeviewcontroller. And I want to hide that button.

我在 pager 中使用了该视图控制器.我想将AddData按钮隐藏在第三页上的scopeviewcontroller中.

I have used this view controller in my pager. I want to hide AddData button in my scopeviewcontroller which is present at the third page.

我在scopeviewcontroller的viewdidload中尝试了此代码.

I tried this code in viewdidload in my scopeviewcontroller.

但是我得到了这个错误:Value of type 'UIViewController' has no member 'AddData'

But is m getting this error: Value of type 'UIViewController' has no member 'AddData'

我在第一个视图控制器中的代码:

my code in first view controller:

class dataviewcontroller: UIViewController {

    @IBOutlet var AddData: UIButton! 
}

我的第二个视图控制器:

class scopeviewcontroller: UIViewController,UITableViewDelegate, UITableViewDataSource {

 override func viewDidLoad() {
        super.viewDidLoad()
let storyboard = UIStoryboard(name: "data", bundle: nil)
       let controller = storyboard.instantiateViewController(withIdentifier: "dataviewcontroller")

        controller.AddData.hidden = true

    }


}

请帮帮我！...谢谢

推荐答案

您无需访问每个添加在寻呼机上的视图控制器上的按钮.您可以隐藏scopeviewcontroller本身上的按钮.在CAPSPageMenuDelegate

You no need to access the button on every view controllers, which you added on the pager. You can hide the button on the scopeviewcontroller itself. with the help of CAPSPageMenuDelegate

在ScopeViewController中，设置寻呼机的委托.

In ScopeViewController, set the delegate of your pager.

fun viewDidLoad() {
   super.viewDidLoad()
   pageMenu.delegate = self 
}

并实施协议CAPSPageMenuDelegate

extension scopeviewcontroller: CAPSPageMenuDelegate {
    func willMoveToPage(_ controller: UIViewController, index: Int) {
        self.AddData.isHidden = (index == 2)
    }
}
