Ionic 1 on iOS Devices - XMLHttpRequest cannot load due to URL access control checks

Hello everybody,
I spent the last 3 days trying to fix this issue, but with no results

I am using Ionic 1, the app is running on android very well, the issue in iOS, the app start normal and every thing is ok until I open a page with $http.get request, it gives me this error in safari console:

- Origin http://localhost:8080 is not allowed by Access-Control-Allow-Origin.
- Failed to load resource: Origin http://localhost:8080 is not allowed by Access--
 Control-Allow-Origin.
XMLHttpRequest cannot load http://example.com/Step/getByProcedureID?procedureID=15&ID=0 due to access control checks.
