iOS 8 requestWhenInUseAuthorization no Popup

Question

I tried to make my AppProject iOS 8 ready. I had read a lot about

[_locationManager requestWhenInUseAuthorization];

and the entry in plist<

Answer 1

Had the same problem caused because I was instantiating CLLocationManager in a local var inside a method, solved it making the CLLocationManager a class property.
After a while I found the solution here, but I'm leaving it here since this is the first result in google, hope I save you some time:

requestWhenInUseAuthorization() not Work in iOS 8 With NSLocationWhenInUseUsageDescription Key in Info.plist
