【FAQ】通过 crontab 定时执行 xcodebuild 打包签名，无法解锁钥匙串？_ios自动化打包签名无法访问钥匙串

参考：https://stackoverflow.com/questions/52197941/xcode-build-works-from-command-line-but-not-in-crontab

crontab 默认使用 root 执行，无法访问用户login keychain

改用 launchd 设置定时任务即可解决：

$ launchctl load -w test.plist

$ launchctl start com.test.start.auto

$ launchctl list | grep com.test.start.auto

test.plist：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
