如何在swiftui中创建键盘应用程序扩展?

问题描述：

我是 swiftUI 的新手.我需要在 swiftui 中创建一个键盘扩展.我只是不知道如何做到这一点.我在互联网上搜索了一整天，但仍然无法找到如何做到这一点.这是我写的一些代码:

I am new to swiftUI.I need to create a keyboard extension in swiftui. I just can't find out how to do that. I am searching on internet for whole day but still can't find out how to do that. Here is some code that I wrote :

struct ContentView: View {
    var body: some View {
        VStack{
           
            keyboard()
        }
        
    }
}

struct keyboard: UIViewControllerRepresentable {
    func makeUIViewController(context: Context) -> UIInputViewController {
        let inputVC = UIInputViewController()
        return inputVC
    }
    
    func updateUIViewController(_ uiViewController: UIInputViewController, context: Context) {
        print("some text")
    }
     
}

上面的代码写在扩展文件夹的 keyboardViewController.swift 文件中，没有给我任何类型的键盘显示.

The above code is written in extension folder's keyboardViewController.swift file and not giving me any kind of keyboard display.

如果我在同一个文件中编写了 UIKit UIInputController(我们创建扩展时创建的文件)代码，那么我只能看到出现了一个键盘扩展.

IF I write UIKit UIInputController (the file created itself when we create an extension) code in same file then only I can see a keyboard extension appearing.

我想在 UIKit Inputviewcontroller 类型的类中设计键盘，然后在 swiftui contentview 中使用 UIViewControllerRepresentable 显示它.

I want to design keyboard in UIKit Inputviewcontroller type of class and then display it using UIViewControllerRepresentable in swiftui contentview.

现在我的问题是->这个方法对吗??如果是，那么请指导我前进.如果不是，请建议我正确的方法.

Now my question is-> Is this Approach right?? IF yes then please guide me ahead. IF no then please suggest me the right approach.

提前致谢！！

这是我使用 UIHostingController 的方法:

Here's my approach using UIHostingController:

当我添加一个新目标键盘"时键盘扩展，XCode 自动生成一个类 KeyboardViewController:

When I added a new target "Keyboard" of keyboard extension, XCode automatically generated a class KeyboardViewController:

class KeyboardViewController: UIInputViewController {
    // some code
    override func viewDidLoad() {
        super.viewDidLoad()
        self.nextKeyboardButton = UIButton(type: .system)
        // some code
    }
    // some code
}

我通过 UIHostingController 添加了视图，我的键盘视图作为它的 rootView.然后将它及其视图添加为 KeyboardViewController 的子项和 KeyboardViewController 的视图:

I added the view through UIHostingController with my keyboard view as the rootView of it. Then added it and its view as children of KeyboardViewController and the view of KeyboardViewController:

class KeyboardViewController: UIInputViewController {
    // some code
    override func viewDidLoad() {
        super.viewDidLoad()
        let hostingController = UIHostingController(rootView: KeyboardView(viewController: self))
        view.addSubview(hostingController.view)
        addChild(hostingController)

        self.nextKeyboardButton = UIButton(type: .system)
        // some code
    }
    // some code
}

而我的 KeyboardView 就像:

struct KeyboardView: View {
    var viewController: KeyboardViewController
    var body: some View {
        // some view as you designed
    }
}

它对我有用.
