vcf, 通讯录导出的一种格式。

一。生成vcf文件

假设要把我们iPhone通讯录里的数据, 生成vcf格式文件。

我们能够借助iCloud。

小技巧：通过iCloud导出iPhone通讯录的方法

当然, 假设你想在应用中, 利用代码生成, 全然能够。先导出通讯录数据, 再解析, 再生成vcf文件就可以。

參考以下代码:

-(NSString*)generateVCardStringWithContacts:(CFArrayRef)contacts {

    NSInteger counter  = 0;

    NSString *vcard = @"";

    for(CFIndex i = 0; i < CFArrayGetCount(contacts); i++) {

        ABRecordRef person = CFArrayGetValueAtIndex(contacts, i);

        NSString *firstName = (NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

        firstName = (firstName ?

firstName : @"");

        NSString *lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);

        lastName = (lastName ? lastName : @"");

        NSString *middleName = (NSString *)ABRecordCopyValue(person, kABPersonMiddleNameProperty);

        NSString *prefix = (NSString *)ABRecordCopyValue(person, kABPersonPrefixProperty);

        NSString *suffix = (NSString *)ABRecordCopyValue(person, kABPersonSuffixProperty);

        // url

        // TODO:

        // IM

        // TODO:

        // Photo

        // TODO:

        vcard = [vcard stringByAppendingString:@"END:VCARD"];

    }

    return vcard;

}

二。

解析vcf文件

用  UIDocumentInteractionController  也就是用QuickLook去显示这个文件。

那他会自己主动的解析, 而且有加入到通讯录选项。

当然。我们也能够自己来解析。

详细代码例如以下:

//解析vcf

-(void)parseVCardString:(NSString*)vcardString

{

    NSArray *lines = [vcardString componentsSeparatedByString:@"\n"];

    for(NSString* line in lines)

    {

        if ([line hasPrefix:@"BEGIN"])

        {

            NSLog(@"parse start");

        }

        else if ([line hasPrefix:@"END"])

        {

            NSLog(@"parse end");

        }

        else if ([line hasPrefix:@"N:"])

        {

            NSArray *upperComponents = [line componentsSeparatedByString:@":"];

            NSArray *components = [[upperComponents objectAtIndex:1] componentsSeparatedByString:@";"];

            NSString * lastName = [components objectAtIndex:0];

            NSString * firstName = [components objectAtIndex:1];

            NSLog(@"name %@ %@",lastName,firstName);

        }

        else if ([line hasPrefix:@"EMAIL;"])

        {

            NSArray *components = [line componentsSeparatedByString:@":"];

            NSString *emailAddress = [components objectAtIndex:1];

            NSLog(@"emailAddress %@",emailAddress);

        }

        else if ([line hasPrefix:@"TEL;"])

        {

            NSArray *components = [line componentsSeparatedByString:@":"];

            NSString *phoneNumber = [components objectAtIndex:1];

            NSLog(@"phoneNumber %@",phoneNumber);

        }

    }

}
