【问题描述】:
我正在尝试获取给定contact 的图像属性。这是我得到的:
型号
struct Contact: Identifiable {
let contact: CNContact
var id: String { contact.identifier }
var image: Data? { contact.imageData }
var givenName: String { contact.givenName }
}
static func fetch(_ completion: @escaping(Result<[Contact], Error>) -> Void) {
let containerID = CNContactStore().defaultContainerIdentifier
let predicate = CNContact.predicateForContactsInContainer(withIdentifier: containerID())
let keysToFetch = [
CNContactImageDataKey,
CNContactImageDataAvailableKey,
CNContactThumbnailImageDataKey,
CNContactGivenNameKey,
CNContactFamilyNameKey,
CNContactPhoneNumbersKey,
CNContactEmailAddressesKey
] as [CNKeyDescriptor]
do {
let contacts = try CNContactStore().unifiedContacts(matching: predicate, keysToFetch: keysToFetch)
completion(.success(contacts.map({ .init(contact: $0)})))
} catch {
completion(.failure(error))
}
}
查看
struct ContactRow: View {
let contact: Contact
var body: some View {
VStack {
HStack {
Image(String(describing: contact.image))
.resizable()
.aspectRatio(contentMode: .fill)
.frame(width: 50, height: 50)
.background(AppColor())
.clipShape(Circle())
.shadow(color: Color.black.opacity(0.1), radius: 1, x: 0, y: 1)
.shadow(color: Color.black.opacity(0.2), radius: 10, x: 0, y: 10)
Text(contact.givenName)
.font(.headline)
.foregroundColor(Color(#colorLiteral(red: 0.2549019754, green: 0.2745098174, blue: 0.3019607961, alpha: 1)))
}
}
}
}
我得到的错误是紫色的,然后说
运行时:SwiftUI:在 /private/var/containers/Bundle/Application/...等的资产目录中找不到名为“可选(38321 字节)”的图像
显然,我在 Apple 提供的 Contacts 应用程序中有联系人图片。
有什么想法吗?
