build package

react-native bundle --platform ios --dev false --entry-file index.ios.js --bundle-output main.jsbundle --assets-dest main.jsbundle

change AppDelegate.m

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

copy main.jsbundle file to XCode project

notice: select Create folder references

problem

• 項目如果設置了__DV__，打離線包的時候會出錯

Property left of AssignmentExpression expected node to be of a type ["LVal"] but instead got "BooleanLiteral"

• 如果項目沒有更改AppDelegate， 會報沒有設置url之類的錯誤

No script URL provided. Make sure the packager is running or you have embedded a JS bundle in your application

• 如果每次打的Release包都一樣，Xcode選擇Project > Clean，然后重新編譯即可
