以下的代码成功地获取并显示了通讯录应用中所有联系人的名字和姓氏，但我遇到了显示电话号码的问题。
如何在列表视图中显示电话号码？

var body: some View {
VStack {
Text("联系人")
.font(.title)
List {
ForEach(contacts, id:\.self) { contact in
VStack{
HStack{
Text("\(contact.givenName)")
Text("\(contact.familyName)")
.fontWeight(.bold)
Spacer()
Button {
print("编辑按钮被点击")
} label: {
Image(systemName:"person.crop.circle.fill.badge.plus")
.font(.title3)
.foregroundColor(.yellow)
}
.buttonStyle(.plain)
}
Text("\(contact.phoneNumbers[0])")
}
}
}
.onAppear{
Task.init{
await fetchAllContacts()
}
}
}
.padding()
}
func fetchAllContacts() async{
let store = CNContactStore()
let keys = [CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactFamilyNameKey] as [CNKeyDescriptor]
let fetchRequest = CNContactFetchRequest(keysToFetch: keys)
do{
try store.enumerateContacts(with: fetchRequest, usingBlock: { contact, result in
contacts.append(contact)
})
}
catch{
print ("错误")
}
}
}

The following code successfully fetches and displays the name and last name of all of the contacts in the Contacts app, what I'm struggling with is displaying the phone numbers.
How can the phone numbers be displayed in a lits view?
struct ContentView: View {
@State var contacts:[CNContact] = []
var body: some View {
VStack {
Text("Conctacts")
.font(.title)
List {
ForEach(contacts, id:\.self) { contact in
VStack{
HStack{
Text("\(contact.givenName)")
Text("\(contact.familyName)")
.fontWeight(.bold)
Spacer()
Button {
print("Edit button was tapped")
} label: {
Image(systemName:"person.crop.circle.fill.badge.plus")
.font(.title3)
.foregroundColor(.yellow)
}
.buttonStyle(.plain)
}
Text("\(contact.phoneNumbers[0])")
}
}
}
.onAppear{
Task.init{
await fetchAllContacts()
}
}
}
.padding()
}
func fetchAllContacts() async{
let store = CNContactStore()
let keys = [CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactFamilyNameKey] as [CNKeyDescriptor]
let fetchRequest = CNContactFetchRequest(keysToFetch: keys)
do{
try store.enumerateContacts(with: fetchRequest, usingBlock: { contact, result in
contacts.append(contact)
})
}
catch{
print ("Error")
}
}
}

更新 Text("\(contact.phoneNumbers[0])") 为：
Text(contact.phoneNumbers[0].value.stringValue)
phoneNumbers是[CNLabeledValue<CNPhoneNumber>]phoneNumbers[0]是CNLabeledValue<CNPhoneNumber>phoneNumbers[0].value是CNPhoneNumberphoneNumbers[0].value.stringValue是表示电话号码的String。
您可能希望使用 phoneNumbers.first 并处理可选项，因为并非所有联系人都具有电话号码。
英文:
Update Text("\(contact.phoneNumbers[0])") to:
Text(contact.phoneNumbers[0].value.stringValue)
phoneNumbersis[CNLabeledValue<CNPhoneNumber>]phoneNumbers[0]isCNLabeledValue<CNPhoneNumber>phoneNumbers[0].valueisCNPhoneNumberphoneNumbers[0].value.stringValueisStringrepresenting the phone number.
You might want to use phoneNumbers.first and deal with the optional since not all contacts have a phone number.
