我正在尝试开发一个应用程序,该应用程序从用户输入一些关于联系人的字段,然后将该联系人导出为VCard。我可以成功导出联系人,但是当我尝试使用iCloud.com上的联系人导入联系人时,图片未被导入。 所有其他信息都是导入的,但不是图片。
我尝试导出VCard的方法有两种。
第一道路
public func getVCard() -> Data?{
var contact = CNMutableContact()
let homeEmail = CNLabeledValue(label:CNLabelHome, value:self.email as! NSString)
contact.emailAddresses = [homeEmail]
let phone = CNLabeledValue(label: CNLabelPhoneNumberMobile, value:CNPhoneNumber(stringValue: self.phone!))
contact.phoneNumbers = [phone]
contact.givenName = self.name!
if let d = self.data{
contact.imageData = d
}
let address = CNMutablePostalAddress()
address.country = self.address!
contact.postalAddresses = [CNLabeledValue(label: CNLabelHome, value: address)]
contact.organizationName = self.company!
contact.jobTitle = title!
let sc1 = CNSocialProfile(urlString: "\(socialMedia1!)", username: self.name!, userIdentifier: self.name!, service: CNContactSocialProfilesKey)
let sc2 = CNSocialProfile(urlString: "\(socialMedia2!)", username: self.name!, userIdentifier: self.name!, service: CNContactSocialProfilesKey)
//contact.socialProfiles = [CNSocialProfile(]
let sc3 = CNSocialProfile(urlString: "\(socialMedia3!)", username: self.name!, userIdentifier: self.name!, service: CNContactSocialProfilesKey)
contact.socialProfiles = [CNLabeledValue(label: "Profile1", value: sc1), CNLabeledValue(label: "Profile2", value: sc2), CNLabeledValue(label: "Profile3", value: sc3)]
contact.note = self.notes!
let urlAddresses = CNLabeledValue(label: CNLabelURLAddressHomePage, value: self.web as! NSString)
contact.urlAddresses = [urlAddresses]
var data: Data?
do{
data = try CNContactVCardSerialization.data(with: [contact])
}catch let error{
print(error.localizedDescription)
}
return data
}
当我调试此功能时,我可以看到联系人对象中的图片数据,但是当导出该VCard并且我尝试在iCloud.com上导入它时,它不会导入该联系人的图片。
现在我用来导出联系人的第二种方法如下,我更喜欢使用这种方法的答案,因为这是最适合我的。
func textBasedVCard()-> Data?{
var string = "BEGIN:VCARD\nVERSION:3.0\n"
string += "N:\(self.name!);\nFN:\(self.name!)\nORG:\(self.company!)\nTITLE:\(self.title!)\nTEL;TYPE=WORK,VOICE:\(self.phone!)\nADR;TYPE=WORK:;;\(self.address!)\nNOTE:\(self.notes!)\nitem1.URL:\(self.web!)\nitem2.URL:\(self.blog!)\nitem3.URL:\(self.socialMedia1!)\nitem4.URL:\(self.socialMedia2!)\nitem5.URL:\(self.socialMedia3!)\nEMAIL;TYPE=PREF,INTERNET:\(self.email!)\nEND:VCARD"
print(string)
let utf8str = string.data(using: String.Encoding.utf8)
//utf8str?.base64EncodedStringWithOptions(NSData.Base64EncodingOptions(rawValue: 0))
if let base64Encoded = utf8str?.base64EncodedString(options: .init(rawValue: 0))
{
return Data(base64Encoded: base64Encoded)!
}
return nil
}
在这种方法中,我不知道如何附加图片数据。请指导我解决这个问题。我将非常感激。感谢。

从上面发布的回复(ABPersonCreatePeopleInSourceWithVCardRepresentation):
地址簿支持vCard 3.0版。
VCARD>照片 - 与vCard关联的个人的图像或照片。它可以指向外部URL,也可以作为Base64编码的文本块嵌入到vCard中。
2.1: PHOTO;JPEG:http://example.com/photo.jpg
2.1: PHOTO;JPEG;ENCODING=BASE64:[base64-data]
3.0: PHOTO;TYPE=JPEG;VALUE=URI:http://example.com/photo.jpg
=> 3.0: PHOTO;TYPE=JPEG;ENCODING=b:[base64-data] // Works in iOS/macOS
4.0: PHOTO;MEDIATYPE=image/jpeg:http://example.com/photo.jpg
4.0: PHOTO:data:image/jpeg;base64,[base64-data]
测试显示第二种方式有效:使用base64编码JPEG照片。
PHOTO;ENCODING=b;TYPE=JPEG:\(base64EncodedImage)
工作PoC:

func vcf() -> String? {
do {
let url = URL(string: self.imageUrl!)
let data = try Data(contentsOf: url!).base64EncodedString()
return generateVCF(withEncodedImage: data)

print(error)

}
}
