支持armv7和arm64的iOS webRTC库

>将为armv7构建的所有* .a组合到libWebRTC-armv7.a：使用如下命令行

libtool -static -o src / out_ios_armv7 / Release-iphoneos / libWebRTC-temp.a src / out_ios_armv7 / Release-iphoneos / * .a

Strip -S -x -o src / out_ios_armv7 / Release-iphoneos / libWebRTC-armv7.a -r src / out_ios_armv7 / Release-iphoneos / libWebRTC-temp.a
>将为arm64构建的所有* .a组合到libWebRTC-arm64.a：

libtool -static -o src / out_ios / Release-iphoneos / libWebRTC-temp.a src / out_ios / Release-iphoneos / * .a

Strip -S -x -o src / out_ios / Release-iphoneos / libWebRTC-arm64.a -r src / out_ios / Release-iphoneos / libWebRTC-temp.a
>创建支持armv7和arm64的libWebRTC：

lipo -create src / out_ios_armv7 / Release-iphoneos / libWebRTC-armv7.a src / out_ios / Release-iphoneos / libWebRTC-arm64.a -output libWebRTC.a

P.s：使用arm64将armv7库构建到分离的文件夹：

export GYP_GENERATORS="ninja"
export GYP_DEFInes="build_with_libjingle=1 build_with_chromium=0 libjingle_objc=1 OS=ios target_arch=armv7"
export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_ios_armv7"
export GYP_CROSSCOMPILE=1
pushd src
gclient runhooks
ninja -C out_ios_armv7/Release-iphoneos AppRTCDemo
popd
