iOS 手动创建 Framework
iOS 手动创建 Framework
MyFramework project
-
new project -> Cocoa touch Framework
-
add headers to
MyFramework.h
// Test.h, Test.m
@interface Test : NSObject
- (NSString* )test;
@end
@implementation Test
- (NSString* )test {
return @"test success";
}
@end
// MyFramework.h
#import <MyFramework/Test.h>
-
add headers to Public
MyFramework target -> Build Phases -> Headers -> Public
-
build target -> MyFramework output
Framework test Demo project
-
copy MyFramework to project
using the MyFramework.framework output from last step
-
Link Framework
target -> Build Phases -> Link Binary With Libraries -> add MyFramework.framework to list
-
copy Framework to app “Framework” destination
target -> Build Phases -> New Copy Files Phases- Destination -> “Framework”
- add MyFramework.framework to list
test
#import <MyFramework/MyFramework.h>
- (void)viewDidLoad {
[super viewDidLoad];
Test* t = [Test new];
NSLog(@"%@", [t test]);
// Do any additional setup after loading the view, typically from a nib.
}
聚合
这是最后一步，上述步骤创建的 Framework 只支持模拟器的指令集，为了能够使 Framework 同时支持真机和模拟器，需要创建一个包含真机指令集和模拟器指令集的 Framework。
指令集表格参考:
arm64 = iPhone 6s/6SP, iPhone 6/6P, iPhone 5s, iPad Air, Retina iPad Mini
armv7s = iPhone 5, iPhone 5c, iPad 4
armv7 = iPhone 3GS, iPhone 4, iPhone 4S, iPod 3G/4G/5G, iPad, iPad 2, iPad 3, iPad Mini
i386 = 32 bit simulator
x86_64 = 64 bit simulator
创建支持模拟器和真机的 Framework:
lipo -create /.../Build/Products/Release-iphonesimulator/MyFramework.framework/MyFramework /.../Build/Products/Release-iphoneos/MyFramework.framework/MyFramework -output MyFramework
查看聚集后的 Framework 支持的指令集:
-> lipo -info MyFramework
-> Architectures in the fat file: MyFramework are: i386 x86_64 armv7 arm64
可以通过创建一个 aggregate 的 target 和脚本来简化这些步骤
Editor -> Add Target -> cross-platform -> Aggregate
新建一个 script，aggregate.sh，放在项目根目录
# 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FMKNAME
# 例如: FMK_NAME = "MyFramework"
FMK_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/${FMK_NAME}.framework
# Working dir will be deleted after the framework creation.
WRK_DIR=build
DEVICE_DIR=${WRK_DIR}/Release-iphoneos/${FMK_NAME}.framework
SIMULATOR_DIR=${WRK_DIR}/Release-iphonesimulator/${FMK_NAME}.framework
# -configuration ${CONFIGURATION}
# Clean and Building both architectures.
xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphoneos clean build
xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphonesimulator clean build
# Cleaning the oldest.
if [ -d "${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 (i386 + armv6/armv7) into one Universal final product.
lipo -create "${DEVICE_DIR}/${FMK_NAME}" "${SIMULATOR_DIR}/${FMK_NAME}" -output "${INSTALL_DIR}/${FMK_NAME}"
rm -r "${WRK_DIR}"
open "${INSTALL_DIR}"
在 aggregate target 的 Build Phases 里的 Run Script 内容中
"${SRCROOT}/aggregate.sh"
最后选择 Generic iOS Device， cmd+B 就能看到聚集后的 Framework
