を助けてください、私は次のコード

ABAddressBookRef addressBook = ABAddressBookCreate(); 

NSArray *allPeople = (NSArray*)ABAddressBookCopyArrayOfAllPeople(addressBook); 
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook); 

tempPeoples= [NSMutableArray arrayWithCapacity:0]; 

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

    ABRecordRef i1=CFArrayGetValueAtIndex(allPeople, i); 

    NSString* name = (NSString *)ABRecordCopyValue(i1,kABPersonFirstNameProperty); 

    [tempPeoples addObject:name]; 

// [peoples addObject:i1]; 

}// end of the for loop 

peoples=[NSArray arrayWithArray:tempPeoples];
