一、设置Release模式

1、首先来选这里

2、选择Run->将Debug改成Release，选择Close，关闭

二、运行项目

1、真机环境下，编译工程

2、模拟器环境下，编译工程

3、选framework，Show in Finder

4、找到，真机和模拟器生成的framework

三、合成

1、lipo -info 命令，可以检测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$ 

说明：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$ 

说明：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"

以上命令太长了，可以直接先cd到 Products 目录下，执行下面短的命令：

lipo -create "Release-iphoneos/OPDiscoveryDF.framework/OPDiscoveryDF" "Release-iphonesimulator/OPDiscoveryDF.framework/OPDiscoveryDF"  -output  "OPDiscoveryDF"

最终，在Products/目录下，生成了一个包含armv7 arm64、i386 x86_64 的全的库。

3、替换，使用

将生成的OPDiscoveryDF文件， 替换到任意一个OPDiscoveryDF.framework里面去， 这个OPDiscoveryDF.framework我们就合成并可以使用了， 支持真机和模拟器使用。
