objective c - NSPointerArray access pointer fails -

i have code in cocoa library:

-(nspointerarray *)  getrequestsfromcalendar:(int) calid {     nspointerarray * reqs=[[nspointerarray alloc] initwithoptions:nspointerfunctionsopaquememory];      for(int i=0;i<5; ++i){         request * newreq=new request();         [reqs addpointer:newreq];     }      (nsuinteger i=0;i<5;++i) {         void * ptr=[reqs pointeratindex:i];         std::cout<<*((request *) ptr)<<std::endl;     } 

here have expected values printed "request1" "request1" "request1" "request1" "request1"

    return reqs; } 

when call function other cocoa library, , access nspointerarray,

nspointerarray * array=[obj getrequestsfromcalendar:1] (nsuinteger i=0; i<[array count]; ++i) {     void * ptr=[array pointeratindex:i];     std::cout<<*((request *) ptr)<<std::endl; } 

prints not expected values ????aod?)@"?? ....

request c++ class overloaded std::ostream & operator << , private members std::string name initialized "request1"

both libraries use automatic reference counting

the pointers seem free after calling function not sure. can help?
