iOS开发- 生成/解析.vcf文件

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);
        NSString *nickName = (NSString *)ABRecordCopyValue(person, kABPersonNicknameProperty);
        NSString *firstNamePhonetic = (NSString *)ABRecordCopyValue(person, kABPersonFirstNamePhoneticProperty);

        NSString *organization = (NSString *)ABRecordCopyValue(person, kABPersonOrganizationProperty);
        NSString *jobTitle = (NSString *)ABRecordCopyValue(person, kABPersonJobTitleProperty);
        NSString *department = (NSString *)ABRecordCopyValue(person, kABPersonDepartmentProperty);

        NSString *compositeName = [NSString stringWithFormat:@"%@%@",firstName,lastName];

                else { //类型解析不出来的
                    counter++;

        }

        // 剩下的不经常使用，我就不写了，要是须要。自己补全
        // 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);
        }
    }

}
