在我的自定义视图的控制器中创建自定义 IBAction [英] Create Custom IBAction in Controller of my Custom View

问题描述

首先我不能发布任何代码，但我会尽量描述我的问题.

firstly I cannot post any Code but I´ll try to describe my problem as best as I can.

好的.我创建了一个自定义 Swift 视图文件作为 view.xib 并将它加载到我的 view.swift 我加载了那个 Xib.Xib 是 imageview 上方的一个简单的 label.我可以在我的 view.swift 文件中创建我的 IBOutlet，例如切换图像或更改标签.view.swift 只是扩展了 UIView.

Ok. I created a Custom Swift View File as view.xib and loading it in my view.swift I loaded that Xib. The Xib is a simple label above a imageview. I can create my IBOutlet in my view.swift file and e.g. switch the image or change the label. view.swift simply extends UIView.

所以现在我将这个视图集成到我的 Storyboard 中，它有一个控制器(我们称之为 otherVC.swift).现在 otherVC.swift 想要获取 view.swift 被触摸的信息.我尝试设置 IBAction 但没有设置选项，仅在 IBOutlet 上设置.在使用 Googe 之后，我发现 UiControl 类具有设置 IBAction 的机制.

So now I integrated this view in my Storyboard which has a Controller (lets call it otherVC.swift). Now otherVC.swift wants to get info that the view.swift is touched. I tried setting a IBAction but there no option to set on, just on IBOutlet. After some Googe I found that the Class UiControl has those mechanics to set a IBAction.

所以我 view.swift 不再扩展 UIView 而是现在 UIControl.之后我可以创建一个带有触摸事件的 IBAction .(如触摸或触摸内部)在模拟器中使用视图运行应用程序时，我可以单击视图，但不会调用 IBAction.

So I view.swift no longer extends UIView but now UIControl. After that I Could create an IBAction with a touch event. (like touch down or touch inside) When running the app with the view in the simulator I can click the view but the IBAction wont be callled.

所以我的问题是如何在其他 VC 中为我的视图设置 IBAction 或者为特定视图创建我自己的 IBActions.

So my question is how can I set a IBAction for my View in a other VC or maybe create my own IBActions for the specific view.

再次..无法发布代码.欢迎带有工作示例的片段或链接

谢谢！

推荐答案

我认为创建自定义 IBAction 会很困难(如果不是不可能的话)，但是您的问题还有许多其他解决方案，例如委托、通知或关闭.我建议您使用闭包，因为我认为这是最简单的方法.

I think that it will be hard to create a custom IBAction (if not impossible), but your problem has many other solutions like delegates, notifications, or closures. I recommend that you use closures as it is the simplest way in my opinion.

以下是如何使用闭包实现这一目标的示例代码:

Below is example code of how you could achieve this with closures:

class View: UIView {

    var someButtonTapped: (UIButton) -> Void = { _ in }

    @IBAction private func someButtonTappedAction(_ sender: UIButton) {
        someButtonTapped(sender)
    }
}

然后在您的控制器中添加:

Then in your controller, add this:

objectOfYourCustomView.someButtonTapped = { (sender: UIButton) in
    // Handle action
}
