以编程方式备份​​完整的iPhone AddressBook [英] Backup complete iPhone AddressBook programmatically

问题描述

我需要以编程方式备份​​包含所有记录（数字，名称，图像......）的所有联系人。我读到了关于AddressBook.framework的内容，但是有一种简单的方法来备份所有联系人吗？

I need to backup all contacts with all records (numbers, names, image, ...) programmatically. I read about the AddressBook.framework, but is there an easy way to make a backup all contacts?

推荐答案

1.一路这样做是为了创建一个包含所有联系人的vCard字符串。像这样：

1.One way of doing this is to create a vCard string with all your contacts. Like this:

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef peopleForBackup  = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFDataRef vcards = (CFDataRef)ABPersonCreateVCardRepresentationWithPeople(peopleForBackup);
vcardString = [[NSString alloc] initWithData:(NSData *)vcards encoding:NSUTF8StringEncoding];

并将此字符串写入文件进行备份。

And write this string to a file for backup.

2.从地址簿中删除当前联系人：

2.Delete current contacts from address book:

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
int arrayCount = CFArrayGetCount(people);
ABRecordRef abrecord;

for (int i = 0; i < arrayCount; i++) {
    abrecord = CFArrayGetValueAtIndex(people, i);
    ABAddressBookRemoveRecord(addressBook,abrecord, NULL);
}
CFRelease(people);

3.要从备份恢复，您只需将vcard文件读入字符串并通过此人进行修改-records in vcard并将它们作为记录添加到地址簿中，然后保存。

3.To restore from the backup you just read the vcard file into a string and itterate through the person-records in the vcard and add them as records to an addressbook, then save it.

ABAddressBookRef addressBook = ABAddressBookCreate();
NSData *stringData = [NSData dataWithContentsOfFile:contactFilePath];
NSString *vcardFromFile = [[NSString alloc] initWithData:stringData encoding:NSUTF8StringEncoding];

CFDataRef vCardData = (CFDataRef)[vcardFromFile dataUsingEncoding:NSUTF8StringEncoding];

ABRecordRef defaultSource = ABAddressBookCopyDefaultSource(addressBook);
CFArrayRef vCardPeople = ABPersonCreatePeopleInSourceWithVCardRepresentation(defaultSource, vCardData);

for (CFIndex index = 0; index < CFArrayGetCount(vCardPeople); index++) {
    ABRecordRef person = CFArrayGetValueAtIndex(vCardPeople, index);
    ABAddressBookAddRecord(addressBook, person, NULL);
    CFRelease(person);
}

CFRelease(vCardPeople);
CFRelease(defaultSource);
bool success = ABAddressBookSave(addressBook, NULL);

这种方法的一个问题是我不知道维持联系人链接的方法（交换，facebook ...）。

A Problem with this approach is that I dont know of a way to maintain the linking of contacts (exchange, facebook...).
