导出 iPhone 地址簿数据库的可能方法

Question

我想将 iPhone 的 AddressBook.sqlitedb 导出到我的 iPhone 应用程序中。

我在网上搜索过，但似乎一切都在“ABAddressBook”上进行迭代

但我想知道是否可以通过编程方式将 iPhone 的 AddressBook.sqlitedb 导出到我的 iPhone 应用程序中？

请告诉我任何有价值的cmets！！！

感谢您的帮助.....

您必须获取每一个值，然后将其插入到您的数据库中。

这是我将 iphone 通讯录放入应用程序 Db 的代码。

只要在你想获取 iphone 通讯录的地方调用下面的方法，但我建议你在 delegat.m 方法中调用这个方法 - DidFinishLanching：

-(void)fetchRecordsFromAddressBook
{
    ABAddressBookRef addressBook = ABAddressBookCreate();
    CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
    CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

//NSArray *addresses = (NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

//[arrayContacts removeAllObjects];

[self emptyDataContext];

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


    ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);


    //////////////////  get first name  ///////////////////

    CFStringRef firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);

    CFStringRef lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);

    CFStringRef nickName = ABRecordCopyValue(ref, kABPersonNicknameProperty);

    CFStringRef middleName = ABRecordCopyValue(ref, kABPersonMiddleNameProperty);


    //////////////////  get image  ///////////////////

//      ABMultiValueRef ContactImage = (ABMultiValueRef)     ABRecordCopyValue(ref,kABPersonImageFormatThumbnail);


    NSData *data=nil;

//  NSLog(@"Image Testing is : %@",ref);

    if(ABPersonHasImageData(ref))
    {
        data = [(NSData *) ABPersonCopyImageData(ref) autorelease];
        if(data)
        {
        //  NSLog(@"Im Testing is : %@",data);

            //image = [[UIImage alloc] initWithData:data];
        }
    }

//      NSLog(@"Im agte is : %@",ContactImage);
//      NSLog(@" Name is : %@",firstName);



    //////////////////  get email  ///////////////////

    ABMultiValueRef emails = (ABMultiValueRef) ABRecordCopyValue(ref, kABPersonEmailProperty);

    NSString *emailID=@"";

    if(ABMultiValueGetCount(emails)>=1)
    {
        emailID = (NSString *)ABMultiValueCopyValueAtIndex(emails,0);
    }


    //////////////////  get phone number  ///////////////////

    ABMultiValueRef phones = (ABMultiValueRef) ABRecordCopyValue(ref, kABPersonPhoneProperty);

    NSString *phone=@"";

    NSString *homeNumber = @"";

    NSString *worknumber = @"";

    if(ABMultiValueGetCount(phones)>=1)
    {
        //int ph = [ABMultiValueCopyValueAtIndex(phones, 0) intValue];
        phone = (NSString *)ABMultiValueCopyValueAtIndex(phones,0);
    }
//  NSLog(@"%@",(NSString*)phone);  


    if(ABMultiValueGetCount(phones)>=2)
    {
        homeNumber = (NSString *)ABMultiValueCopyValueAtIndex(phones,1);
    }

    if(ABMultiValueGetCount(phones)>=3)
    {
        worknumber = (NSString *)ABMultiValueCopyValueAtIndex(phones,2);
    }


    NSMutableArray *arrayContacts = [[NSMutableArray alloc] init ];


    /////////////////////////////          insert into array               ////////////////////////////

    arrayContacts = [CoreDataAPIMethods getObjectsFromContext:@"AllContactData" :@"Index" :NO :self.managedObjectContext];

    ////////////////////////////         insert Index         ///////////////////////////////
    int NewEntryID;

    if ([arrayContacts count] > 0) 
    {
        AllContactData * Contacdata = [arrayContacts objectAtIndex:0];

        NewEntryID = [Contacdata.Index intValue] +1;

    }
    else 
    {
        NewEntryID = 1;
    }

    NSString *capitalisedSentence = 
    [(NSString *)firstName stringByReplacingCharactersInRange:NSMakeRange(0,1)  
                                        withString:[[(NSString *)firstName  substringToIndex:1] capitalizedString]];

    AllContactData *Contactitem=(AllContactData *)[NSEntityDescription insertNewObjectForEntityForName:@"AllContactData" inManagedObjectContext:self.managedObjectContext];

//      NSLog(@"%@",capitalisedSentence);

    Contactitem.Name = capitalisedSentence;

    Contactitem.LastName = (NSString*)lastName;

    Contactitem.NickName = (NSString*)nickName;

    Contactitem.MiddleName = (NSString*)middleName;

    Contactitem.Email=(NSString*)emailID;

    phone = [phone stringByReplacingOccurrencesOfString:@"(" withString:@""];

    phone = [phone stringByReplacingOccurrencesOfString:@")" withString:@""];

    phone = [phone stringByReplacingOccurrencesOfString:@"+" withString:@""];

    phone = [phone stringByReplacingOccurrencesOfString:@" " withString:@""];

    phone = [phone stringByReplacingOccurrencesOfString:@"-" withString:@""];

    NSLog(@"The Replacing Stinr is : %@", phone);

    Contactitem.PhoneNumber=(NSString*)phone;

    Contactitem.HomeNumber=(NSString*)homeNumber;

    Contactitem.WorkNumber=(NSString*)worknumber;

    Contactitem.Index = [NSNumber numberWithInt:NewEntryID];

    Contactitem.Image = data;

//      NSLog(@"Image in databse  is : %@",(NSData *)ContactImage);

    if(firstName!=nil)
    {
        CFRelease(firstName);
    }
    CFRelease(ref);

}
CFRelease(allPeople);


/////////////////////////////         save entries          ////////////////////////////

NSError *error;
if (![managedObjectContext save:&error]) {
    // Handle the error...
}


}



-(void)emptyDataContext
{

self.managedObjectContext = [(Dial_Up_AppAppDelegate*)[UIApplication sharedApplication].delegate managedObjectContext];

NSLog(@"managedObjectContext=%@",self.managedObjectContext);
// Get all counties, It's the top level object and the reference cascade deletion downward
NSMutableArray* mutableFetchResults = [CoreDataAPIMethods getObjectsFromContext:@"AllContactData" :@"Name" :YES :self.managedObjectContext];
// Delete all Counties
for (int i = 0; i < [mutableFetchResults count]; i++) {
    [managedObjectContext deleteObject:[mutableFetchResults objectAtIndex:i]];
}
//[mutableFetchResults release];
// Update the data model effectivly removing the objects we removed above.
NSError *error;
if([mutableFetchResults count] > 0)
{

    if (![managedObjectContext save:&error]) {
        // Handle the error.
        //NSLog([error domain]);
    }

}

}

希望这会对你有所帮助。
