Ios 如何创建要在共享表中使用的vCard/vcf文件？

我不熟悉swift，我发现的方法在我的问题上不受欢迎。我正在构建一个目录应用程序，并从API中提取联系人数据，而不是从手机的通讯簿中

在iOS中，如果您转到通讯簿，您可以选择一个联系人并选择“共享联系人”，这将显示共享表。我想在我的应用程序中使用这个确切的功能

我想我已经弄清楚了共享表，下面是我的代码：

    @IBAction func actShare(sender: AnyObject) {

    let activityViewController = UIActivityViewController(activityItems: ["text" as NSString], applicationActivities: nil)
    presentViewController(activityViewController, animated: true, completion: {})
}

我想将

“text”更改为NSString

作为vCard，因为这是iOS从通讯簿中共享的对象，对吗？假设我是对的，我想从我自己的应用程序的联系人对象创建一个vCard，以便将其共享到适当的应用程序（电子邮件、短信等）

如何在Swift中实现这一点？如果我错了，请纠正我，告诉我需要做什么。谢谢

编辑：好的，这是我的更改

@IBAction func actShare(sender: AnyObject) {
    do {
        var contactData = NSData()
        try contactData = CNContactVCardSerialization.dataWithContacts([createContact()])

        let activityViewController = UIActivityViewController(activityItems: [contactData as NSData], applicationActivities: nil)
        presentViewController(activityViewController, animated: true, completion: {})
    } catch {
        print("CNContactVCardSerialization cannot save address")
    }

及

但是，当我单击“共享”按钮并打开“共享表”时，我选择了要共享的应用程序，但它没有按预期添加/附加联系人数据。如何实现此目的？

您可以使用CNContact（需要iOS 9）：

这里的技巧是使用

CNContactVCardSerialization.dataWithContacts

将联系人保存到VCard（.vcf）文件，然后将文件URL传递到

UIActivityViewController

。活动视图控制器从文件扩展名检测VCard格式，并显示支持该格式的应用程序（如消息、邮件、便笺、空投等）

例如：

@IBAction func buttonTapped(button: UIButton) {

    let contact = createContact()

    do {
        try shareContacts([contact])
    }
    catch {
        // Handle error
    }
}

func shareContacts(contacts: [CNContact]) throws {

    guard let directoryURL = NSFileManager.defaultManager().URLsForDirectory(.CachesDirectory, inDomains: .UserDomainMask).first else {
        return
    }

    var filename = NSUUID().UUIDString

    // Create a human friendly file name if sharing a single contact.
    if let contact = contacts.first where contacts.count == 1 {

        if let fullname = CNContactFormatter().stringFromContact(contact) {
            filename = fullname.componentsSeparatedByString(" ").joinWithSeparator("")
        }
    }

    let fileURL = directoryURL
        .URLByAppendingPathComponent(filename)
        .URLByAppendingPathExtension("vcf")

    let data = try CNContactVCardSerialization.dataWithContacts(contacts)

    print("filename: \(filename)")
    print("contact: \(String(data: data, encoding: NSUTF8StringEncoding))")

    try data.writeToURL(fileURL, options: [.AtomicWrite])

    let activityViewController = UIActivityViewController(
        activityItems: [fileURL],
        applicationActivities: nil
    )

    presentViewController(activityViewController, animated: true, completion: {})
}

func createContact() -> CNContact {

    // Creating a mutable object to add to the contact
    let contact = CNMutableContact()

    contact.imageData = NSData() // The profile picture as a NSData object

    contact.givenName = "John"
    contact.familyName = "Appleseed"

    let homeEmail = CNLabeledValue(label:CNLabelHome, value:"john@example.com")
    let workEmail = CNLabeledValue(label:CNLabelWork, value:"j.appleseed@icloud.com")
    contact.emailAddresses = [homeEmail, workEmail]

    contact.phoneNumbers = [CNLabeledValue(
        label:CNLabelPhoneNumberiPhone,
        value:CNPhoneNumber(stringValue:"(408) 555-0126"))]

    return contact
}

从iOS应用程序创建联系人并通过网络共享非常简单 外部应用程序

首先，您需要创建共享按钮操作，如下所示：-

-(void)shareContactAction:(UIButton*)sender
{  
    CNMutableContact *selectedCon = [[CNMutableContact alloc] init];
    selectedCon.givenName = @"ABC";
    selectedCon.familyName = @"XYZ";
    NSString *phoneNum = @"+91-XXXXXXXXXXX"
    CNLabeledValue *contactNum1 = [CNLabeledValue labeledValueWithLabel:CNLabelHome value:[CNPhoneNumber phoneNumberWithStringValue:phoneNum]];
    selectedCon.phoneNumbers = @[contactNum1];
    NSString *url=[self saveContactDetailsToDocDir:selectedCon];
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[@"Contact", [NSURL fileURLWithPath:url]] applicationActivities:nil];
    [self presentViewController:activityViewController animated:YES completion:nil];     
}

然后可以调用下面的函数，该函数将返回 上述按钮事件中的联系人卡

为Swift 4更新：

@IBAction func buttonTapped(button: UIButton) {

    let contact = createContact()

    do {
        try shareContacts(contacts: [contact])
    }
    catch {
    // Handle error
    }
}

func shareContacts(contacts: [CNContact]) throws {

    guard let directoryURL = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask).first else {
    return
    }

    var filename = NSUUID().uuidString

    // Create a human friendly file name if sharing a single contact.
    if let contact = contacts.first, contacts.count == 1 {

    if let fullname = CNContactFormatter().string(from: contact) {
        filename = fullname.components(separatedBy: " ").joined(separator: "")
    }
    }

    let fileURL = directoryURL
    .appendingPathComponent(filename)
    .appendingPathExtension("vcf")

    let data = try CNContactVCardSerialization.data(with: contacts)

    print("filename: \(filename)")
    print("contact: \(String(describing: String(data: data, encoding: String.Encoding.utf8)))")

    try data.write(to: fileURL, options: [.atomicWrite])

    let activityViewController = UIActivityViewController(
    activityItems: [fileURL],
    applicationActivities: nil
    )

    present(activityController, animated: true, completion: nil)
}

func createContact() -> CNContact {

    // Creating a mutable object to add to the contact
    let contact = CNMutableContact()

    contact.imageData = NSData() as Data // The profile picture as a NSData object

    contact.givenName = "John"
    contact.familyName = "Appleseed"

    let homeEmail = CNLabeledValue(label:CNLabelHome, value:"john@example.com")
    let workEmail = CNLabeledValue(label:CNLabelWork, value:"j.appleseed@icloud.com")
    contact.emailAddresses = [homeEmail, workEmail]

    contact.phoneNumbers = [CNLabeledValue(
    label:CNLabelPhoneNumberiPhone,
    value:CNPhoneNumber(stringValue:"(408) 555-0126"))]

    return contact
}

成功的方法：

首先获取所有联系人，然后保存，然后保存make.vcf文件，并在电子邮件、WhatsApp、消息、Skype和iPhone文件中共享.vcf

谢谢-我刚用一个新问题更新了我的初始帖子。不过，我认为你的回答会解决这个问题。我会试试看，然后再打给你。非常感谢！非常感谢你！这非常有效。我现在明白了。不过，我还有最后一个问题。当我共享联系人时，.vcf有一个长名称，如“6DD3C04D-08C1-44C7-8A7E-F08C6F0CB5CD.vcf”。我可以把它改成JohnnyAppleseed.vcf吗，就像你从自己的通讯录中分享联系人一样？编辑：哦，我明白了！我通过附加PathComponent（nsuid（）.uuiString）忽略了.url。非常感谢你

CNContactFormatter

将在这方面帮助您。我已经更新了代码，向您展示了如何使用它。如果联系人没有姓名（无论出于何种原因），或者如果您一次共享多个联系人（在这种情况下，可能不需要使用第一个姓名），则返回UUID字符串。很高兴提供帮助！请在答案上做标记，就好像它回答了你的问题一样。做得好。。。！只有复制和过去的代码这些方法工作的大部分，但我不能得到一个缩略图或接触图像显示。我收到此错误

qltumbnailerrordomain code=0“无法生成缩略图”

Im使用

let image=UIImage（名为：“ExistingContactPlaceHolderPic”）contact.imageData=image？.pngData（）

有什么想法吗？

    selectedCon.phoneNumbers = @[contactNum1];
    NSString *url=[self saveContactDetailsToDocDir:selectedCon];
