What is the difference between the app ID and the bundle ID? Where is the app ID in the Xcode project?
提问by user255607
In the pList file, there is a bundle ID of the form com.mycompany.myapp, but Apple also provides an app ID on the developer portal.
在 pList 文件中，有一个形式为 com.mycompany.myapp 的 bundle ID，但 Apple 还在开发者门户上提供了一个应用 ID。
Thus, basically, what is the use of the bundle ID? Where can we find the app ID in the Xcode project?
因此，基本上，bundle ID 的用途是什么？我们在 Xcode 项目中在哪里可以找到应用 ID？

app ID 和 bundle ID 有什么区别？
Because most people think of the App ID as a string, they think it is interchangeable with Bundle ID. It appears this way because once the App ID is created in Member Center you only ever use the App ID Prefix which matches the Bundle ID of the Application Bundle
因为大多数人认为 App ID 是一个字符串，他们认为它可以与 Bundle ID 互换。之所以出现这种情况，是因为一旦在会员中心创建了 App ID，您就只能使用与应用程序包的包 ID 匹配的 App ID 前缀
Where is the app ID in the Xcode project?
Xcode 项目中的应用 ID 在哪里？
You don't find the App ID in Xcode. It is an object (not just a string) in Member Center. Xcode is where the Bundle ID is found. It is specified when creating a new project. (screenshot below) Each Target in a project will have a unique Bundle ID. It can be found/changed by selecting the project in the Project Navigator the choosing the Target and either General or Info from the Jump Bar.
The Xcode interface is described hereor here(depending on how Apple is feeling that day).
您在 Xcode 中找不到 App ID。它是会员中心中的一个对象（不仅仅是一个字符串）。Xcode 是 Bundle ID 所在的位置。创建新项目时指定。（下面的屏幕截图）项目中的每个 Target 都将有一个唯一的 Bundle ID。可以通过在项目导航器中选择项目、从跳转栏中选择目标和常规或信息来找到/更改它。
What is the use of the bundle ID?
捆绑ID有什么用？
It uniquely defines each App. It is specified in Xcode. A single Xcode project can have multiple Targets and therefore output multiple apps. A common use case for this is an app that has both lite/free and pro/full versions or is branded multiple ways.
它唯一地定义了每个应用程序。它在 Xcode 中指定。一个 Xcode 项目可以有多个 Targets，因此可以输出多个应用程序。一个常见的用例是具有精简版/免费版和专业版/完整版或以多种方式标记的应用程序。

Definitions
定义
App ID
Think of this as an object in Member Center with lots of metadata including:
- App ID Description
- App ID Prefix
- App ID Suffix
- App Services
App ID Description
Alphanumeric plus spaces
Sometimes you are shown this instead of the App ID, or a dropdown is sorted by this App ID
(I always make this the same as the App ID with the dots changed to spaces)
App ID Prefix
Select from a list of available hashes in the Team ID format (see below)
You pretty much always want to select the one labeled "(Team ID)"
App ID Suffix
A reverse-domain name style string
This must match the Bundle ID specified in Xcode
Explicit App ID
Describes an App ID with an App ID Suffix that contains no wildcards
Can only be associated with a single app (by exactly matching a Bundle ID)
Compatible with all App Services
Wildcard App ID
Describes an App ID with an App ID Suffix that ends with an asterisk
Can be associated with multiple apps (matched similar to CLI/bash shell wildcard matching)
Not compatible with Game Center, In-App Purchase, or Push NotificationsApp Services
App Services
A combination of
- Data Protection
- Game Center
- iCloud
- In-App Purchase
- Inter-App Audio
- Passbook
- Push Notifications
Team ID
A 10 character alphanumeric hash
Unique to every Developer Account (as in the account that costs $99/yr, not every developer on the account)
Apple ID
A unique integer assigned by Apple when an app is first created in iTunes Connect.
Bundle ID
A reverse-domain name style string
Defined in Xcode
Uniquely identifies an Application Bundle on a device or simulator
Must have a matching App ID registered with Apple in order to deploy
Used to distinguish app updates vs. new apps
Application Bundle
The result of the Build process in Xcode. Though it has an extention of .ipa it is a zip file. The content is a very specific directory structure and holds everything the App needs. It looks like someone took a Mac .app file from /Applications, put in a directory named Payload, zipped it, then change the extension.
Target
Every Xcode project has at least 1 target. Each target specifies an app that can be built from the project.
SKU
Apple allows you to store a Stock Keeping Unitstring (alphanumeric, cannot have spaces) for each app in iTunes Connect. Apple doesn't do anything with this except display it on reports generated for your record keeping.
应用程序 ID
将此视为会员中心中的一个对象，其中包含许多元数据，包括：
- 应用 ID 描述
- 应用 ID 前缀
- 应用 ID 后缀
- 应用服务
应用 ID 描述
字母数字加空格
有时你会看到这个而不是 App ID，或者下拉列表按这个 App ID 排序
（我总是把它和 App ID 一样，点变成空格）
应用 ID 前缀
从 Team ID 格式的可用哈希列表中选择（见下文）
您几乎总是想选择标有“（团队 ID）”的那个
应用 ID 后缀
反向域名样式字符串
这必须与 Xcode 中指定的 Bundle ID 匹配
显式应用程序 ID
使用不包含通配符的 App ID 后缀描述 App ID
只能与单个应用相关联（通过与 Bundle ID 完全匹配）
与所有应用服务兼容
通配符应用程序 ID
使用以星号结尾的 App ID 后缀描述 App ID
可以关联多个应用程序（匹配类似于 CLI/bash shell 通配符匹配）
与Game Center、In-App Purchase或Push NotificationsApp Services不兼容
应用服务
组合
- 数据保护
- 游戏中心
- 云
- 在应用程序内购买
- 应用间音频
- 存折
- 推送通知
团队标识
一个 10 个字符的字母数字哈希
每个开发者帐户都是独一无二的（例如在费用为 99 美元/年的帐户中，并非帐户中的每个开发者）
苹果ID
在 iTunes Connect 中首次创建应用程序时由 Apple 分配的唯一整数。
捆绑 ID
反向域名样式字符串
在 Xcode 中定义
唯一标识设备或模拟器上的应用程序包
必须具有在 Apple 注册的匹配 App ID 才能部署
用于区分应用更新与新应用
应用程序包
在 Xcode 中构建过程的结果。虽然它的扩展名为 .ipa，但它是一个 zip 文件。内容是一个非常具体的目录结构，包含应用程序所需的一切。看起来有人从 /Applications 获取了一个 Mac .app 文件，放入一个名为 Payload 的目录中，压缩它，然后更改扩展名。
目标
每个 Xcode 项目至少有 1 个目标。每个目标指定一个可以从项目构建的应用程序。
单品
Apple 允许您在 iTunes Connect 中为每个应用程序存储一个Stock Keeping Unit字符串（字母数字，不能有空格）。除了在为您的记录保存而生成的报告中显示它之外，Apple 不会对此做任何事情。

Bundle ID is the identifier of an App, but App ID is not. App ID is the connection between App and provisioning profile.
Bundle ID 是 App 的标识符，但 App ID 不是。App ID 是 App 和配置文件之间的连接。
From "About Bundle IDs" section in here, you can see, "A bundle ID precisely identifies a single app".
从此处的“关于捆绑 ID”部分，您可以看到“捆绑 ID 精确标识单个应用程序”。
And from here, you can see, "An app ID's primary use is as part of a provisioning profile; it specifies which apps are authorized by the profile to be signed and launched.".
从这里，您可以看到，“应用 ID 的主要用途是作为配置文件的一部分；它指定配置文件授权哪些应用程序进行签名和启动。”。
App ID has 2 parts: "bundle seed ID" and "bundle ID search string". Bundle seed IDmakes Apps share keychain data, that is to say, it's the key chain entry of Apps which have the same bundle seed ID. Bundle ID search stringdefines how many Apps are covered by this App ID. If you use a Wildcard App ID, that means many Apps will be authorized by the provisioning profile associated with this App ID. For more details please refer to here.
App ID 有两部分：“bundle 种子 ID”和“bundle ID 搜索字符串”。 Bundle Seed ID使 App 共享钥匙串数据，也就是说，它是具有相同捆绑种子 ID 的 App 的钥匙串入口。 Bundle ID 搜索字符串定义了此 App ID 涵盖的 App 数量。如果您使用通配符 App ID，这意味着许多 App 将通过与此 App ID 关联的配置文件进行授权。有关详细信息，请参阅此处。

Simply, A bundle ID precisely identifies a single app. A bundle ID is used during the development process to provision devices and by the operating system when the app is distributed to customers.
简单地说，一个 bundle ID 精确地标识了一个单一的应用程序。在开发过程中使用捆绑 ID 来配置设备，并在将应用分发给客户时由操作系统使用。
During the development process, you use an app's bundle ID in many different places to identify the app. 
在开发过程中，您在许多不同的地方使用应用程序的包 ID 来标识应用程序。
Whereas, An App ID is a two-part string used to identify one or more apps from a single development team.
而 App ID 是一个由两部分组成的字符串，用于标识来自单个开发团队的一个或多个应用程序。
The Team ID is supplied by Apple and is unique to a specific development team, while the bundle ID search string is supplied by you to match either the bundle ID of a single app or a set of bundle IDs for a group of your apps.
团队 ID 由 Apple 提供，对于特定的开发团队是唯一的，而捆绑 ID 搜索字符串由您提供，以匹配单个应用的捆绑 ID 或一组应用的捆绑 ID。
There are two types of App IDs: an explicit App ID, used for a single app, and wildcard App IDs, used for a set of apps.
有两种类型的 App ID：显式 App ID，用于单个 App，和通配符 App ID，用于一组 App。

Multiple apps can share the same App ID. The App ID does not uniquely identify an application.
多个应用程序可以共享同一个应用程序 ID。App ID 不唯一标识应用程序。
An App ID is a two-part string used to identify one or more apps from a single development team
App ID 是一个由两部分组成的字符串，用于标识来自单个开发团队的一个或多个应用程序
The ID that you see in iTunes Connect, which isunique across apps, is known as the application's Apple ID. I apologize for the confusion because no one at Apple will.
您在 iTunes Connect 中看到的 ID在应用程序中是唯一的，称为应用程序的 Apple ID。我为造成的混乱道歉，因为 Apple 没有人会这样做。

App id is a combination of two strings, are separated by a period (.). String1 is a team id, Which is assigned to the development team.(provided by apple) String2 is a bundle id, is selected by you.
App id 是两个字符串的组合，用句点 (.) 分隔。 String1 是团队 id，分配给开发团队。（由苹果提供） String2 是捆绑 id，由您选择。
App id is having two types.
App id 有两种类型。
Explicit App ID:Here team id is used to match only one app with a specific bundle id. This app id is used to match one apponly. example: TEAM_ID.BUNDLE_ID
Wildcard App IDs:Here team id is used to match multiple apps with multiple bundle ids. This app id is used to match multiple apps. examples: TEAM_ID.BUNDLE_ID1, TEAM_ID.BUNDLE_ID2 ...
显式应用 ID：这里的团队 ID 用于仅匹配一个具有特定捆绑包 ID 的应用。此应用 ID 仅用于匹配一个应用。示例：TEAM_ID.BUNDLE_ID
通配符应用 ID：这里的团队 ID 用于匹配具有多个捆绑包 ID 的多个应用。此应用 ID 用于匹配多个应用。示例：TEAM_ID.BUNDLE_ID1、TEAM_ID.BUNDLE_ID2 ...
