xcode - 关于Xcode＆＃34;组织标识符＆＃34;，应该是唯一的，可能会产生什么问题？

我想知道＆＃34;组织标识符＆＃34;你必须提供，或者通过连接＆＃34;产品名称＆＃34;自动创建。和＆＃34;公司名称＆＃34;

通过简短的搜索，我发现组织标识符用于识别您的应用。

我的问题如下：

此标识符在您的应用之间或开发者之间应该是唯一的？换句话说，这个标识符在App Store中是唯一的吗？
通常，标识符开头的com用于标识下一个单词是否描述公司？这与域名表示有关，例如org，net等吗？
最后，在创建此标识符时，您应该忽略或注意创建此标识符时的任何建议，因为据我所知，一旦发布到App Store，此标识符就无法更改。换句话说，如果没有正确设置，那么这个标识符可以创建什么问题，以及如何避免。

组织标识符必须是唯一的。通常，开发人员的网站是反向DNS表示法。也就是说，如果开发人员的网站是import java.io.*; import java.net.*; import java.util.*; public class SynchClient { public static void main(String[] args) throws IOException { InetAddress host = null; final int PORT = 1234; Socket socket; Scanner networkInput,keyboard; PrintWriter output; try { host = InetAddress.getLocalHost(); } catch(UnknownHostException uhEx) { System.out.println("\nHost ID not found!\n"); } socket = new Socket(host, PORT); networkInput = new Scanner(socket.getInputStream()); output = new PrintWriter(socket.getOutputStream(),true); keyboard = new Scanner(System.in); String message, response; do { System.out.print("\nEnter message ('QUIT' to exit): "); message = keyboard.nextLine(); if (message.length() < 4) { System.out.print("\nPlease enter a value greater than 4 characters: "); message = keyboard.nextLine(); } output.println(message); if (!message.equals("QUIT")) { response = networkInput.nextLine(); System.out.println("\n" + response); } }while (!message.equals("QUIT")); try { System.out.println("\nClosing down connection...\n"); socket.close(); } catch(IOException ioEx) { System.out.println("\n* Disconnection problem! *\n"); } } }，那么组织标识符将变为public class SynchServer { public static void main(String[] args) throws IOException { ServerSocket serverSocket = null; final int PORT = 1234; Socket client; ClientHandler handler; try { serverSocket = new ServerSocket(PORT); } catch (IOException ioEx) { System.out.println("\nUnable to set up port!"); System.exit(1); } System.out.println("\nServer running...\n"); do { //Wait for client. client = serverSocket.accept(); System.out.println("\nNew client accepted.\n"); handler = new ClientHandler(client); handler.start(); }while (true); } } class ClientHandler extends Thread { private Socket client; private Scanner input; private PrintWriter output; private static String text = ""; public ClientHandler(Socket socket) throws IOException { client = socket; input = new Scanner(client.getInputStream()); output = new PrintWriter(client.getOutputStream(),true); } public void run() { String head, tail, received; received = input.nextLine(); // create head and tail in case first input is rep: or app: head = received.substring(0, 4); tail = received.substring(4); while (!received.equals("QUIT")) { if (head.equals("rep:")) { changeText(tail); output.println(text); // input for next one } else if (head.equals("app:")) { appendText(tail); output.println(text); // get input for next } else { //must be some random thing that just needs to be echoed output.println(text); } //Get next input received = input.nextLine(); //and set the head and tail again head = received.substring(0, 4); tail = received.substring(4); } try { System.out.println("Closing down connection..."); client.close(); } catch(IOException ioEx) { System.out.println("* Disconnection problem! *"); } } private synchronized void changeText(String changedText) { text = changedText; } private synchronized void appendText(String appendedText) { text += appendedText; } }。

根据Apple的说法，这个捆绑标识符在App Store上的应用程序中应该是唯一的（如果你想在Apple的App Store上分发你的应用程序）。因此，确保这种唯一性的一种方法是选择一个唯一的组织标识符。

创建应用程序的两个版本（iOS，macOS），标识符也需要不同，一种方法是在标识符字段中的应用程序名称之前附加public class SynchClient { public static void main(String[] args) throws IOException { InetAddress host = null; final int PORT = 1234; Socket socket; Scanner networkInput,keyboard; PrintWriter output; try { host = InetAddress.getLocalHost(); } catch(UnknownHostException uhEx) { System.out.println("\nHost ID not found!\n"); } socket = new Socket(host, PORT); networkInput = new Scanner(socket.getInputStream()); output = new PrintWriter(socket.getOutputStream(),true); keyboard = new Scanner(System.in); String message, response; do { System.out.print("\nEnter message ('QUIT' to exit): "); message = keyboard.nextLine(); while (message.length() < 4) { System.out.print("\nPlease enter 4 or more characters: "); message = keyboard.nextLine(); } output.println(message); if (!message.equals("QUIT")) { response = networkInput.nextLine(); System.out.println("\n" + response); } }while (!message.equals("QUIT")); try { System.out.println("\nClosing down connection...\n"); socket.close(); } catch(IOException ioEx) { System.out.println("\n* Disconnection problem! *\n"); } } }或example.com。 / p>

将应用程序分发到App Store后，无法更改标识符。

最后，对于最后一个问题，我看不出这部分有任何问题。选择一个好的，独特的，漂亮的组织标识符已经足够了。
