vcf, 通訊錄導出的一種格式。

一。生成vcf文件

如果要把我們iPhone通訊錄裡的數據, 生成vcf格式文件。

我們可以借助iCloud。

小技巧：通過iCloud導出iPhone通訊錄的方法

當然, 如果你想在應用中, 利用代碼生成, 完全可以。先導出通訊錄數據, 再解析, 再生成vcf文件即可。

參考下面代碼:

-(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 *jobTitle = (NSString *)ABRecordCopyValue(person, kABPersonJobTitleProperty);
        NSString *department = (NSString *)ABRecordCopyValue(person, kABPersonDepartmentProperty);
        
        NSString *compositeName = [NSString stringWithFormat:@"%@%@",firstName,lastName];
        
        if(i > 0) {
            vcard = [vcard stringByAppendingFormat:@"\n"];
        }
        
        vcard = [vcard stringByAppendingFormat:@"BEGIN:VCARD\nVERSION:3.0\nN:%@;%@;%@;%@;%@\n",
                 (firstName ? firstName : @""),

                 (middleName ? middleName : @""),
                 (prefix ? prefix : @""),
                 (suffix ? suffix : @"")
                 ];

                else {//類型解析不出來的

                }
            }
        }
        
        // Tel
        ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
        if(phoneNumbers) {
            for (int k = 0; k < ABMultiValueGetCount(phoneNumbers); k++) {
                NSString *label = (NSString*)ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(phoneNumbers, k));
                NSString *number = (NSString *)ABMultiValueCopyValueAtIndex(phoneNumbers, k);
                NSString *labelLower = [label lowercaseString];

                }
            }
        }
        
        // Address
        ABMultiValueRef address = ABRecordCopyValue(person, kABPersonAddressProperty);
        if(address) {
            for (int k = 0; k < ABMultiValueGetCount(address); k++) {
                NSString *label = (NSString*)ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(label, k));
                NSDictionary *dic = (NSDictionary *)ABMultiValueCopyLabelAtIndex(address, k);

                NSString* state = [dic valueForKey:(NSString *)kABPersonAddressStateKey];
                NSString* street = [dic valueForKey:(NSString *)kABPersonAddressStreetKey];
                NSString* zip = [dic valueForKey:(NSString *)kABPersonAddressZIPKey];
                NSString* countryCode = [dic valueForKey:(NSString *)kABPersonAddressCountryCodeKey];
                NSString *type = @"";
                NSString *labelField = @"";
                counter++;
                
                if([labelLower isEqualToString:@"work"]) type = @"WORK";
                else if([labelLower isEqualToString:@"home"]) type = @"HOME";
                else if(label && [label length] > 0)
                {
                    labelField = [NSString stringWithFormat:@"item%d.X-ABLabel:%@\n",counter,label];
                }
                
                vcard = [vcard stringByAppendingFormat:@"item%d.ADR;type=%@:;;%@;%@;%@;%@;%@\n%@item%d.X-ABADR:%@\n",
                         counter,
                         type,
                         (street ? street : @""),
                         (city ? city : @""),
                         (state ? state : @""),
                         (zip ? zip : @""),
                         (country ? country : @""),
                         labelField,
                         counter,
                         (countryCode ? countryCode : @"")
                         ];
            }
        }
        
        
        // 剩下的不常用，我就不寫了，要是需要，自己補全
        // 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去顯示這個文件。 那他會自動的解析, 並且有添加到通訊錄選項。

當然，我們也可以自己來解析。

具體代碼如下:

//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);
        }
    }
    
}
