ios - 自定义 URL 方案错误 : This app is not allowed to query for scheme

Question

我有 2 个应用程序，一个客户端和一个服务器。我正在尝试使用 URL 方案在 iOS 应用程序之间进行应用程序间通信

(我引用了这个 https://developer.apple.com/documentation/uikit/inter-process_communication/allowing_apps_and_websites_to_link_to_your_content/defining_a_custom_url_scheme_for_your_app 作为指南)

这是客户端的plist

    <key>CFBundleExecutable</key>
    <string>$(EXECUTABLE_NAME)</string>

iOS端代码

@IBAction func tapToClient(){
        let urlsrting = "com.test.serverEndApp://requestInfo?userID='22'"
        let url = URL(string: urlsrting)!
        if UIApplication.shared.canOpenURL(url){

            if #available(iOS 10.0, *) {
                UIApplication.shared.open(url, options: [:]) { (success) in
                    print(" this is \(success)")
                }

            } else {
                UIApplication.shared.openURL(url)
            }
        }else{

            let alertController = UIAlertController(title: "Error", message:
                "There is no such server app here", preferredStyle: .alert)
            alertController.addAction(UIAlertAction(title: "Dismiss", style: .default))

            self.present(alertController, animated: true, completion: nil)

        }
    }

服务器端

代码

 @IBAction func tapToServer(){
        let urlsrting = "com.test.clientEndApp://provideInfo?username='Debanjan'"
        let url = URL(string: urlsrting)!
        if UIApplication.shared.canOpenURL(url){
            if #available(iOS 10.0, *) {
                UIApplication.shared.open(url, options: [:]) { (success) in
                    print(" this is \(success)")
                }

            } else {
                UIApplication.shared.openURL(url)
            }
        }else{
            let alertController = UIAlertController(title: "Error", message:
                "There is no such client app here", preferredStyle: .alert)
            alertController.addAction(UIAlertAction(title: "Dismiss", style: .default))

            self.present(alertController, animated: true, completion: nil)

        }
    }
}

我从他们两个那里得到的只是

-canOpenURL: failed for URL: "com.test.clientEndApp://provideInfo?username='Debanjan'" - error: "This app is not allowed to query for scheme com.test.clientendapp"

-canOpenURL: failed for URL: "com.test.serverEndApp://requestInfo?userID='22'" - error: "This app is not allowed to query for scheme com.test.serverendapp"

我已经执行了所有步骤，但仍处于这种状态。帮助我意识到我做错了什么

我在 iPhone 8 iOS 12.2 模拟器上运行它，在 xcode 12.2 上

如果您注册，则以相反的方式进行:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>com.test.clientEndApp</string>
</array>

你应该调用这个方案

let urlsrting = "com.test.clientEndApp://provideInfo?username='Debanjan'"

您的 LSApplicationQueriesSchemes 中缺少 com.test.
