thanks in advance.

the uiimagepickercontroller doesn't give camera's location. have add cllocationmanager in app. initiate/delegate self. , call "startupdatinglocation". in "-(void)locationmanager:(cllocationmanager *)manager didupdatetolocation:(cllocation *)newlocation fromlocation:(cllocation *)oldlocation", able location "newlocation".

now if want save image photo library, can use https://github.com/gpambrozio/gusutils
