安裝 gomobile

gomobile 需要go 1.6及以上

go install golang.org/x/mobile/cmd/gomobile@latest

# 或
go get golang.org/x/mobile/cmd/gomobile@latest

配置環(huán)境變量

GOPATH=$HOME/go
GOPATH_BIN=$HOME/go/bin
PATH=$PATH:$GOPATH
PATH=$PATH:$GOROOT
PATH=$PATH:$GOPATH_BIN

創(chuàng)建Go模塊

mkdir hqkit
cd hqkit
go mod init hqkit

初始化 gomobile

gomobile init

# 安裝bind依賴
go get golang.org/x/mobile/bind

編寫代碼后，打包庫

rm -rf HqKit.xcframework 
gomobile bind -target=ios -o HqKit.xcframework ./hqkit

# gomobile -v bind -target=<ios,android ...> -o <xxx.xcframework or xxx.aar or xxx.jar> <<go_pacakge_name_path>
# -o ios為 xxx.xcframework, android 為 xxx.aar或xxx.jar
