营销发布号是针对客户的，称为版本号。它从1.0开始，主要更新到2.0、3.0，次要更新到1.1、1.2，错误修复到1.0.1、1.0.2。这个数字是面向发布和新功能。

构建号主要是在此之前构建的内部编号。但有些使用其他数字，如存储库的分支编号。这个编号应该是唯一的，以区分几乎相同的不同构建。

如您所见，版本号不是必需的，由您决定要使用哪个版本号。所以如果你把Xcode更新到一个主版本，build字段是空的。版本字段不能为空!

获取构建号作为NSString变量:

NSString * appBuildString = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

获取版本号作为NSString变量:

NSString * appVersionString = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

如果你想把两者都放在一个NSString中:

NSString * versionBuildString = [NSString stringWithFormat:@"Version: %@ (%@)", appVersionString, appBuildString];

这是用Xcode版本4.6.3 (4H1503)测试的。版本号通常用括号/大括号表示。构建号为十六进制或十进制。

在Xcode中，你可以通过在项目设置的Run脚本构建阶段中放置以下内容，将构建号自动增加为十进制数

#!/bin/bash    
buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

对于十六进制构建号，请使用此脚本

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$((0x$buildNumber)) 
buildNumber=$(($buildNumber + 1)) 
buildNumber=$(printf "%X" $buildNumber)
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

感谢@nekno和@ale84的精彩回答。

但是，我修改了@ale84的脚本，它很少增加浮点的构建号。

incl的值可以根据您的浮动格式要求进行更改。 例如:如果incl = .01，输出格式为 .．. 1.19, 1.20, 1.21 .．.

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
incl=.01
buildNumber=`echo $buildNumber + $incl|bc`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

我在Xcode 14.2上，并将以下bash脚本添加到项目包中的.sh文件中。然后我使用一个运行脚本构建阶段来调用这个脚本。当我存档项目时，版本和包更新了几次，但随后停止了增量。关于为什么脚本不会继续增加有任何反馈吗?感谢反馈。

currentVersionString=$(/usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "$PROJECT_DIR/SupportingFiles/$INFOPLIST_FILE")
currentBuildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$PROJECT_DIR/SupportingFiles/$INFOPLIST_FILE")

newBuildNumber=$((currentBuildNumber + 1))

IFS='.' read -ra version <<< "$currentVersionString"
version[2]=$((version[2] + 1))
newVersionString="${version[0]}.${version[1]}.${version[2]}"

/usr/libexec/PlistBuddy -c "Set :CFBundleShortVersionString $newVersionString" "$PROJECT_DIR/SupportingFiles/$INFOPLIST_FILE"
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $newBuildNumber" "$PROJECT_DIR/SupportingFiles/$INFOPLIST_FILE"

另一种方法是在appDelegate didFinishLaunchingWithOptions中设置版本号:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
     NSString * ver = [self myVersion];
     NSLog(@"version: %@",ver);

     NSUserDefaults* userDefaults = [NSUserDefaults standardUserDefaults];
     [userDefaults setObject:ver forKey:@"version"];
     return YES;
}

- (NSString *) myVersion {
    NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
    NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
    return [NSString stringWithFormat:@"%@ build %@", version, build];
}

Build号是一个内部编号，表示应用程序的当前状态。它与版本号不同，因为它通常不是面向用户的，也不像版本号通常会表示任何差异/功能/升级。

你可以这样想:

Build (CFBundleVersion): The number of the build. Usually you start this at 1 and increase by 1 with each build of the app. It quickly allows for comparisons of which build is more recent and it denotes the sense of progress of the codebase. These can be overwhelmingly valuable when working with QA and needing to be sure bugs are logged against the right builds. Marketing Version (CFBundleShortVersionString): The user-facing number you are using to denote this version of your app. Usually this follows a Major.minor version scheme (e.g. MyAwesomeApp 1.2) to let users know which releases are smaller maintenance updates and which are big deal new features.

To use this effectively in your projects, Apple provides a great tool called agvtool. I highly recommend using this as it is MUCH more simple than scripting up plist changes. It allows you to easily set both the build number and the marketing version. It is particularly useful when scripting (for instance, easily updating the build number on each build or even querying what the current build number is). It can even do more exotic things like tag your SVN for you when you update the build number.

使用它:

在Xcode中，在版本控制下，设置你的项目使用“Apple Generic”。 在终端 agvtool新版本1(将Build号设置为1) agvtool new-marketing-version 1.0(将Marketing版本设置为1.0)

请参阅agvtool的手册页，以获得大量有用的信息

(只是把这个留在这里供我自己参考。)这将显示你在Xcode目标中看到的"version"和"build"字段的version和build:

- (NSString*) version {
    NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
    NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
    return [NSString stringWithFormat:@"%@ build %@", version, build];
}

在斯威夫特

func version() -> String {
    let dictionary = NSBundle.mainBundle().infoDictionary!
    let version = dictionary["CFBundleShortVersionString"] as? String
    let build = dictionary["CFBundleVersion"] as? String
    return "\(version) build \(build)"
}
