一、設定Release模式
1、首先來選這裡
2、選擇Run->将Debug改成Release，選擇Close，關閉
二、運作項目
1、真機環境下，編譯工程
2、模拟器環境下，編譯工程
3、選framework，Show in Finder
4、找到，真機和模拟器生成的framework
三、合成
1、lipo -info 指令，可以檢測framework
lmydeMacBook-Pro:~ lmy$ lipo -info /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF
Architectures in the fat file: /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF are: armv7 arm64
lmydeMacBook-Pro:~ lmy$
說明：真集framework中包含 armv7 arm64
lmydeMacBook-Pro:~ lmy$ lipo -info /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF
Architectures in the fat file: /Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF are: i386 x86_64
lmydeMacBook-Pro:~ lmy$
說明：真集framework中包含 i386 x86_64
2、合成
lipo -create "/Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF" "/Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF" -output "/Users/lmy/Library/Developer/Xcode/DerivedData/CloudLearning_OPDiscoveryDF-fyoydhuesnoytlbbbitgpbkgyzwh/Build/Products/OPDiscoveryDF"
以上指令太長了，可以直接先cd到 Products 目錄下，執行下面短的指令：
lipo -create "Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF" "Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF" -output "OPDiscoveryDF"
最終，在Products/目錄下，生成了一個包含armv7 arm64、i386 x86_64 的全的庫。
3、替換，使用
将生成的OPDiscoveryDF檔案， 替換到任意一個OPDiscoveryDF.framework裡面去， 這個OPDiscoveryDF.framework我們就合成并可以使用了， 支援真機和模拟器使用。
