修改联系人的步骤大致如下

1

获取底层地址簿中已有的联系人对应的ABRecordRef记录

2

根据需要修改的属性,调用ABRecordSetValue()函数修改ABRecordRef记录中指定属性的值

3

修改完成后调用ABAddressBookSave()函数将刚刚所做的修改保存到底层地址簿

注意

为了让界面能动态显示ABMutableMultiValueRef包含的每一条数据,程序定义了addLabelAndTextField:propertyKey:方法来动态加载ABMutableMultiValueRef中的每一条数据----程序为每条数据添加一行,用UILabel显示这条数据的label,用UITextField显示这条数据的value
