Hi All, I want to convert NSMutableArray to NSArray to it gives error following is code

ABAddressBookRef addressBook = ABAddressBookCreate(); CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

tempPeoples=[[NSMutableArray alloc]init];

for(int i=0;i<nPeople;i++){

    ABRecordRef i1=CFArrayGetValueAtIndex(allPeople, i);
    [tempPeoples addObject:i1];

//  [peoples addObject:i1];

}// end of the for loop

// Peoples is NSArray

// peoples=[[NSArray alloc] initWithArray: tempPeoples];

peoples=[NSArray arrayWithArray:tempPeoples];

Please help
