i gettings following warnings

1.call function 'abrecordcopyvalue' returns corefoundation object +1 retain count 2.object leaked:allocated object not referenced later in execution , has retain count of +1

please tell me how overcome problem

if using arc, can use bridge cast:

cfstringref name = (cfstringref)abrecordcopyvalue(person,kabpersonfirstnameproperty); [ssemailvc setname:(__bridge nsstring*)name]; cfrelease(name); 

or bridge transfer:

nsstring * name = (__bridge_transfer nsstring *)abrecordcopyvalue(person,kabpersonfirstnameproperty); [ssemailvc setname:name]; 

---

if using mrc:

cfstringref name = (cfstringref)abrecordcopyvalue(person,kabpersonfirstnameproperty); [ssemailvc setname:(nsstring*)name]; cfrelease(name);
