React native 问题总结

“ Application Wevaha has not been registered.This is either due to a require() error during intialization or failure to call”。

It is likely that you already have another React Native packager server running for another app or that the app name in AppDelegate.m and your index.js is not the same.
Try closing all terminal windows,double check the value of moduleName and run the project again.

“Cmd-R not refreshing in simulator”

Turns out it is a simple hardware keyboard setting in the simulator menu
