os提供了对通讯录操作的组建，其中一个是直接操作通讯录，另一个是调用通讯录的UI组建。实现方法如下：

添加AddressBook.framework到工程中。

代码实现：

    -(IBAction)onClickbutton:(id)sender
    {
        NSMutableArray* personArray =[[[NSMutableArray alloc] init] autorelease];
        ABAddressBookRef addressBook =ABAddressBookCreate();
        NSString*firstName,*lastName,*fullName;
        personArray =(NSMutableArray*)ABAddressBookCopyArrayOfAllPeople(addressBook);
        if([sender tag]==0){

            for(id *person in personArray)
            {
                firstName =(NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);
                firstName =[firstName stringByAppendingFormat:@" "];
                lastName =(NSString*)ABRecordCopyValue(person, kABPersonLastNameProperty);   
                fullName =[firstName stringByAppendingFormat:@"%@",lastName];
                NSLog(@"===%@",fullName);
                ABMultiValueRef phones =(ABMultiValueRef)ABRecordCopyValue(person, kABPersonPhoneProperty);
                for(int i =0;i <ABMultiValueGetCount(phones); i++)
                { 
                    NSString*phone =(NSString*)ABMultiValueCopyValueAtIndex(phones, i);
                    NSLog(@"===%@",phone);
                }
                ABMultiValueRef mails =(ABMultiValueRef)ABRecordCopyValue(person, kABPersonEmailProperty);
                for(int i =0;i <ABMultiValueGetCount(mails); i++)
                { 
                    NSString*mail =(NSString*)ABMultiValueCopyValueAtIndex(mails, i);
                    NSLog(@"==%@",mail);
                }       
            }   
        }else{
            //删除信息
            //返回所有联系人到一个数组中
            CFArrayRef personArray =ABAddressBookCopyArrayOfAllPeople(addressBook);
            CFIndex personCount =ABAddressBookGetPersonCount(addressBook);
              for(int i =0;i<personCount;i++){
                  ABRecordRefref=CFArrayGetValueAtIndex(personArray, i);
                  CFStringRef firstName1 =ABRecordCopyValue(ref, kABPersonFirstNameProperty);
                  CFStringRef lastName1 =ABRecordCopyValue(ref, kABPersonLastNameProperty);
                  NSString*contactFirstLast =[NSString stringWithFormat: @"%@%@",(NSString*)firstName1,(NSString*)lastName1];
                if([contactFirstLast isEqualToString:@"徐梦"]){
                    //删除联系人
                    ABAddressBookRemoveRecord(addressBook,ref,nil);
                }
            }
            //保存电话本
            ABAddressBookSave(addressBook,nil);  
            //释放内存
            //CFRelease(personRef);
    //        CFRelease(addressbookRef); 
        }
    }
