最近在项目中遇到使用.dylib后缀的库不能在APP Store中上架，所以只能改用framework形式的库。

以下几个文件下载路径：https://download.csdn.net/download/zhuyunier/10715963

编译方式采用cmake，toochain中为iOS工具链iOS.cmake，目录结构如下：

CMake编译脚本如下：

#****************************This is Project Info****************************

 endif()
 
ADD_DEFINITIONS("-Wall")
ADD_DEFINITIONS("-fPIC")
ADD_DEFINITIONS("-Wl,-lm")
ADD_DEFINITIONS("-std=c++11")
SET(IPHONE_VERSION_MIN "10.0" CACHE STRING "IOS minimum os version.")
SET(CMAKE_CXX_FLAGS "-Wall -fPIC -Wl,-lm -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS")

SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fobjc-abi-version=2 -fobjc-arc -isysroot ${CMAKE_OSX_SYSROOT} -framework AVX -miphoneos-version-min=${IPHONE_VERSION_MIN}")

set_target_properties(${PROJECT_NAME} PROPERTIES FRAMEWORK TRUE MACOSX_FRAMEWORK_IDENTIFIER com.skylight.SKYObject MACOSX_FRAMEWORK_INFO_PLIST Info.plist PUBLIC_HEADER ../SKYObect.h XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY "iPhone Developer")

CMake说明：

• PROJECT(SKYObject)中SKYObject为framework的名字；
• IPHONE_VERSION_MIN 为支持的iOS的最低系统，与Info.plist中MinimumOSVersion值相对应
• 链接其他的framework使用-framework XXX
• INCLUDE_DIRECTORIES为头文件路径
• LINK_DIRECTORIES为库路径
• set_target_properties中MACOSX_FRAMEWORK_IDENTIFIER后边紧跟的值为Info.plist中CFBundleIdentifier，必须设置；MACOSX_FRAMEWORK_INFO_PLIST为使用自己的Info.plist模板，后边紧跟的值为Info.plist的相对路径；PUBLIC_HEADER指定需要的头文件，后边紧跟的值为头文件的相对路径。

Info.plist如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

toochain工具链iOS.cmake如下：

# This file is based off of the Platform/Darwin.cmake and Platform/UnixPaths.cmake
# files which are included with CMake 2.8.4
# It has been altered for iOS development

# Options:
#
# IOS_PLATFORM = OS (default) or SIMULATOR or SIMULATOR64
#   This decides if SDKS will be selected from the iPhoneOS.platform or iPhoneSimulator.platform folders
#   OS - the default, used to build for iPhone and iPad physical devices, which have an arm arch.
#   SIMULATOR - used to build for the Simulator platforms, which have an x86 arch.
#
# CMAKE_IOS_DEVELOPER_ROOT = automatic(default) or /path/to/platform/Developer folder
#   By default this location is automatcially chosen based on the IOS_PLATFORM value above.
#   If set manually, it will override the default location and force the user of a particular Developer Platform
#
# CMAKE_IOS_SDK_ROOT = automatic(default) or /path/to/platform/Developer/SDKs/SDK folder
#   By default this location is automatcially chosen based on the CMAKE_IOS_DEVELOPER_ROOT value.
#   In this case it will always be the most up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.
#   If set manually, this will force the use of a specific SDK version

# Macros:
#
# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE)
#  A convenience macro for setting xcode specific properties on targets
#  example: set_xcode_property (myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1")

# find_host_package (PROGRAM ARGS)
#  A macro used to find executable programs on the host system, not within the iOS environment.
