ios - 创建通用的 iOS 框架

Question

我已经创建了一个通用的 iOS 框架。在 Xcode 中，它是一个“聚合目标”，它使用构建脚本和 lipo 命令行工具将 iphonesimulator- 和 iphoneos-binaries 放入一个容器二进制文件中。构建 iphonesimulator-binary 的命令是

xcodebuild -project MMFramework.xcodeproj -scheme "$SCHEME_NAME" \
    -sdk iphonesimulator -configuration ${CONFIGURATION} clean build \
    CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphonesimulator

(我已经将项目名称替换为“MMFramework”，但这不是问题所在。)

使用 Xcode 6 时，iphonesimulator 二进制文件构建没有问题。使用 Xcode 7 时出现错误，例如

// (with Xcode 7)
#import <sys/utsname.h>
^^Error: Could not build module 'Darwin'

此外，xcodebuild 在 Xcode7 中的行为有所不同。 Xcode 6 将我的 xcodebuild 命令翻译成如下调用

# with Xcode 6

但是有了Xcode 7，你可以看到它终于相信iphonesimulator运行在ARM平台上了。它似乎对构建 iphonesimulator- 还是 iphoneos-binary 感到困惑。

那么，有没有人用Xcode 7成功搭建过一个通用的iOS框架呢？还是我做错了什么？

Xcode 7 是我系统上选择的版本:

$ xcode-select -p
/Applications/Xcode.app/Contents/Developer

它安装在/Applications/Xcode.app 下，Xcode 6 位于/Applications/Xcode6.app 下。

这是我的构建脚本:

#!/bin/sh

echo "XXX 0"

######################
# Options
######################


FRAMEWORK_NAME="MMFramework"
SCHEME_NAME="iOSMMFramework"

SIMULATOR_LIBRARY_PATH="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${FRAMEWORK_NAME}.framework"
DEVICE_LIBRARY_PATH="${BUILD_DIR}/${CONFIGURATION}-iphoneos/${FRAMEWORK_NAME}.framework"
UNIVERSAL_LIBRARY_DIR="${BUILD_DIR}/${CONFIGURATION}-iphoneuniversal"
FRAMEWORK="${UNIVERSAL_LIBRARY_DIR}/${FRAMEWORK_NAME}.framework"


######################

echo "XXX 1"

xcodebuild -project MMFramework.xcodeproj -scheme "$SCHEME_NAME" -sdk iphonesimulator -configuration ${CONFIGURATION} clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphonesimulator 2>&1

echo "XXX 2"

xcodebuild -project MMFramework.xcodeproj -scheme "$SCHEME_NAME" -sdk iphoneos -configuration ${CONFIGURATION} clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphoneos 2>&1

######################

######################

cp -r "${DEVICE_LIBRARY_PATH}/." "${FRAMEWORK}"


######################
# Make an universal binary
######################

echo "XXX 7"

lipo "${SIMULATOR_LIBRARY_PATH}/${FRAMEWORK_NAME}" "${DEVICE_LIBRARY_PATH}/${FRAMEWORK_NAME}" -create -output "${FRAMEWORK}/${FRAMEWORK_NAME}" | echo

echo "XXX 8"

# For Swift framework, Swiftmodule needs to be copied in the universal framework
if [ -d "${SIMULATOR_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/" ]; then
    cp -f ${SIMULATOR_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/* "${FRAMEWORK}/Modules/${FRAMEWORK_NAME}.swiftmodule/" | echo
fi

if [ -d "${DEVICE_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/" ]; then
    cp -f ${DEVICE_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/* "${FRAMEWORK}/Modules/${FRAMEWORK_NAME}.swiftmodule/" | echo
fi

echo "XXX 9"

我的 Xcode 通用目标包含两个构建阶段:“目标依赖项(0 项)”和“运行脚本”。脚本是:

iOSMMFramework/universal-buildscript.sh 2>&1 |tee ~/my-log.txt

my-log.txt 仅用于调试，这是我从中获取日志文件的地方。

Xcode 6 的 SDKROOT 为“iphonesimulator8.4”，Xcode 7 的 SDKROOT 为“iphonesimulator9.2”。

而且我已将构建文件夹位置自定义为 PROJECT_DIR/build。 (尽管将其改回默认位置并没有什么不同。)

在 Xcode 7.2 (7C68) 中它不起作用。使用 Xcode 6.4 (6E35b) 它可以工作。

Answer 1

我正在使用相同的命令并能够创建通用框架。

xcodebuild -project "${PROJECT_FILE_PATH}" \
    -target "${TARGET_NAME}" \
    -configuration "${CONFIGURATION}" \
    -sdk "${1}" \
    ONLY_ACTIVE_ARCH=NO \
    BUILD_DIR="${BUILD_DIR}" \
    OBJROOT="${OBJROOT}" \
    BUILD_ROOT="${BUILD_ROOT}" \
    SYMROOT="${SYMROOT}"

您可以尝试从 xcodebuild 中删除 clean build 命令吗？我使用不同的 shellscript。
