创建 Framework

Framework

设置

添加 .h .m .swift 文件

#import <UIKit/UIKit.h>

//! Project version number for RWUIControlsFramework.
FOUNDATION_EXPORT double RWUIControlsFrameworkVersionNumber;

//! Project version string for RWUIControlsFramework.
FOUNDATION_EXPORT const unsigned char RWUIControlsFrameworkVersionString[];

// In this header, you should import all the public headers of your framework using statements like #import <RWUIControlsFramework/PublicHeader.h>

#import <RWUIControlsFramework/RWKnobControl.h>
#import <RWUIControlsFramework/RWRibbonView.h>

模拟器和真机通用 Framework

创建Cross-platform -> Other -> Aggregate Target。

Aggregate

添加脚本

# Sets the target folders and the final framework product.
# 如果工程名称和Framework的Target名称不一样的话，要自定义FRAMEWORK_NAME
FRAMEWORK_NAME=${PROJECT_NAME}
# Install dir will be the final output to the framework.
# The following line create it in the root folder of the current project.
INSTALL_DIR=${SRCROOT}/Products/${FRAMEWORK_NAME}.framework
# Working dir will be deleted after the framework creation.
WORKING_DIR=build
DEVICE_DIR=${WORKING_DIR}/Release-iphoneos/${FRAMEWORK_NAME}.framework
SIMULATOR_DIR=${WORKING_DIR}/Release-iphonesimulator/${FRAMEWORK_NAME}.framework
# -configuration ${CONFIGURATION}
# Clean and Building both architectures.
xcodebuild -configuration "Release" -target "${FRAMEWORK_NAME}" -sdk iphoneos clean build
xcodebuild -configuration "Release" -target "${FRAMEWORK_NAME}" -sdk iphonesimulator clean build
# Cleaning the oldest.
if [ -d "${INSTALL_DIR}" ]
then
rm -rf "${INSTALL_DIR}"
fi
mkdir -p "${INSTALL_DIR}"
cp -R "${DEVICE_DIR}/" "${INSTALL_DIR}/"
# Uses the Lipo Tool to merge both binary files ([arm_v7] [i386] [x86_64] [arm64]) into one Universal final product.
lipo -create "${DEVICE_DIR}/${FRAMEWORK_NAME}" "${SIMULATOR_DIR}/${FRAMEWORK_NAME}" -output "${INSTALL_DIR}/${FRAMEWORK_NAME}"
rm -r "${WORKING_DIR}"
open "${INSTALL_DIR}"

Bundle

由于默认在 macOS 中使用，需要进行一些其他的设置：

选择 Bundle，在 Build Settings 中搜索base sdk,选中该行并按下 delete。这样就把 macOS 改为 iOS。

可选：搜索product name，双击编辑，将内容替换为和 Framework 名字一样：

默认情况下, 具有两个分辨率的图像可以产生一些有趣的结果。例如, 当你包括视网膜 @2x 版本。他们将合并成一个多分辨率的 TIFF, 这不是一件好事。搜索hidpi并将COMBINE_HIDPI_IMAGES设置更改为NO.

为了确保在 build framework 时一起 build bundle。

要将 bundle 文件与得到的通用 framework 放在同一路径，需要在上面的脚本底部添加：

BUNDLE_NAME="bundle name"

# Copy the resources bundle
ditto "${BUILT_PRODUCTS_DIR}/${BUNDLE_NAME}.bundle" \
"${SRCROOT}/Products/${BUNDLE_NAME}.bundle"

如果遇到报错提示：

ld: -bundle and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together

需要将 bundle target 的 bitcode 选项设置为 NO：

Bitcode

使用 Framework

import RWUIControlsFramework

class ViewController: UIViewController {
    @IBOutlet weak var ribbonView: RWRibbonView!
    @IBOutlet weak var knobControl: RWKnobControl!
    ...
}

问题

将 framework 拖入 Embedded Binaries

Embedded

Unknown class *** in Interface Builder file.

Interface Builder 与源文件建立连接。

但是, 包含类似 “fat” 二进制文件的应用程序不会通过app store验证。在提交包含通用框架的应用程序之前, 需要剪裁二进制文件, 以便只包含 iOS 本机代码。可以使用以下脚本执行此操作:

FRAMEWORK=<要剪裁的Framework名称>
echo "Trimming $FRAMEWORK..."

FRAMEWORK_EXECUTABLE_PATH="${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/$FRAMEWORK.framework/$FRAMEWORK"

EXTRACTED_ARCHS=()

for ARCH in $ARCHS
do
    echo "Extracting $ARCH..."
    lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
    EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
done

echo "Merging binaries..."
lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
rm "${EXTRACTED_ARCHS[@]}"

rm "$FRAMEWORK_EXECUTABLE_PATH"
mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

echo "Done."
