Problem : My ionic project doesn't show anything after i run on iOS device


I start building new ionic project with simple command on ionic website ionic start myApp sidemen and then update iOS platform to 4.0.0, after that I do command cordova build iOS. Everything works fine, my project was build success.

Then I go to Xcode and start to run the project on my iPhone6 device. It can run and show splash screen for a while.
But after that it alway show just white screen, it doesn’t show anythings like header, footer or content anymore.

How can I fix this problem.

Cordova CLI: 6.1.1
Ionic Version: 1.2.4
Ionic CLI Version: 1.7.14
Ionic App Lib Version: 0.7.0

ios-sim version: 5.0.8
OS: Mac OS X El Capitan
Node Version: v4.2.1
Xcode version: Xcode 7.3 Build version 7D175

Note that I didn’t write anything in www folder. just new project I have make.

Please give me any suggestion. Thank you.
