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 *lastNamePhonetic = (NSString *)ABRecordCopyValue(person, kABPersonLastNamePhoneticProperty);
        
        NSString *organization = (NSString *)ABRecordCopyValue(person, kABPersonOrganizationProperty);

        NSString *department = (NSString *)ABRecordCopyValue(person, kABPersonDepartmentProperty);
        
        NSString *compositeName = [NSString stringWithFormat:@"%@%@",firstName,lastName];
        
        if(i > 0) {

                }

                NSString* zip = [dic valueForKey:(NSString *)kABPersonAddressZIPKey];
                NSString* countryCode = [dic valueForKey:(NSString *)kABPersonAddressCountryCodeKey];
                NSString *type = @"";

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

        // 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:@"
"];
    
    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);
        }
    }
    
}
