i implemented RadaeePDF a while ago. Last week i tried to add CoreLocation to my project and then a crash occured in APP_Init(). I had to revert my changes i made for CoreLocation and then RadaeePDF worked again.
Which version of library are you using ? You can download the last version at this link
Have you added in project other frameworks besides CoreLocation? We've just tried to add CoreLocation in the last demo version and everything works correctly.
