AddressBook框架的大多数部分在iOS 9中已弃用。在新的Contacts Framework中，documentation仅显示如何获取与NSPredicate匹配的记录，但是如果我想要all记录怎么办？
这两个答案都只将带有defaultContainerIdentifier的容器的触点加载。在用户具有多个容器的情况下（即同时用于存储联系人的Exchange和iCloud帐户），这只会从配置为默认帐户的帐户中加载联系人。因此，它不会按问题作者的要求加载all个联系人。
您可能要做的是获取所有容器并对其进行迭代以从每个容器中提取所有联系人。以下代码段是如何在其中一个应用程序（在Swift中）中执行此操作的示例：
lazy var contacts: [CNContact] = {
let contactStore = CNContactStore()
let keysToFetch = [
CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName),
CNContactEmailAddressesKey,
CNContactPhoneNumbersKey,
CNContactImageDataAvailableKey,
CNContactThumbnailImageDataKey]
// Get all the containers
var allContainers: [CNContainer] = []
do {
allContainers = try contactStore.containersMatchingPredicate(nil)
} catch {
print("Error fetching containers")
}
var results: [CNContact] = []
// Iterate all containers and append their contacts to our results array
for container in allContainers {
let fetchPredicate = CNContact.predicateForContactsInContainerWithIdentifier(container.identifier)
do {
let containerResults = try contactStore.unifiedContactsMatchingPredicate(fetchPredicate, keysToFetch: keysToFetch)
results.appendContentsOf(containerResults)
} catch {
print("Error fetching results for container")
}
}
return results
}()

NSLog(@"The contactsArray are - %@",arrayTableData);
}
dispatch_async(dispatch_get_main_queue(), ^{

从iOS9的联系人框架中获取全名，电子邮件ID，电话号码，个人资料图片
注意，没有姓名的联系人也已处理。
步骤1

我正在尝试使用此代码，它工作正常。我可以在swift3最新框架中使用以下代码使用联系人获取所有联系人的详细信息：
let requestForContacts = CNContactFetchRequest(keysToFetch: [CNContactIdentifierKey as CNKeyDescriptor, CNContactFormatter.descriptorForRequiredKeys(for: CNContactFormatterStyle.fullName), CNContactPhoneNumbersKey as CNKeyDescriptor ,CNContactImageDataKey as CNKeyDescriptor,CNContactEmailAddressesKey as CNKeyDescriptor,CNContactBirthdayKey as CNKeyDescriptor])
do {
try self.store.enumerateContacts(with: requestForContacts) { contact, stop in
print("contact:\(contact)")
self.contacts.append(contact)
}
} catch {
print(error)
}
for contact in self.contacts {
print(contact)
let firstName = contact.givenName
nameArray.append(firstName)
print("first:\(firstName)")
let phoneNumber = (contact.phoneNumbers[0].value).value(forKey: "digits")
phoneNumberArray.append(phoneNumber as! String)
let emailAddress = contact.emailAddresses[0].value(forKey: "value")
emailAddressArray.append(emailAddress as! String)
}
Cody在Swift 3中的回应：
import Contacts
然后在您使用的任何函数中：
let store = CNContactStore()
store.requestAccess(for: .contacts, completionHandler: {
granted, error in
guard granted else {
let alert = UIAlertController(title: "Can't access contact", message: "Please go to Settings -> MyApp to enable contact permission", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
return
}
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeys(for: .fullName), CNContactPhoneNumbersKey] as [Any]
let request = CNContactFetchRequest(keysToFetch: keysToFetch as! [CNKeyDescriptor])
var cnContacts = [CNContact]()
do {
try store.enumerateContacts(with: request){
(contact, cursor) -> Void in
cnContacts.append(contact)
}
} catch let error {
NSLog("Fetch contact error: \(error)")
}
print(">>>> Contact list:")
for contact in cnContacts {
let fullName = CNContactFormatter.string(from: contact, style: .fullName) ?? "No Name"
print("\(fullName): \(contact.phoneNumbers.description)")
}
})
现在不推荐使用iOS9 ABAddressBookRef，以便使用此框架从手机中获取所有联系人并添加此功能，您将获得联系人数组。
像这样在.h类中导入Contact框架
#import <Contacts/Contacts.h>
然后在.m文件中添加此方法
-(void)contactsFromAddressBook{
//ios 9+
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(@"error fetching contacts %@", error);
} else {
NSString *phone;
NSString *fullName;
NSString *firstName;
NSString *lastName;
UIImage *profileImage;
NSMutableArray *contactNumbersArray;
for (CNContact *contact in cnContacts) {
// copy data to my custom Contacts class.
firstName = contact.givenName;
lastName = contact.familyName;
if (lastName == nil) {
fullName=[NSString stringWithFormat:@"%@",firstName];
}else if (firstName == nil){
fullName=[NSString stringWithFormat:@"%@",lastName];
}
else{
fullName=[NSString stringWithFormat:@"%@ %@",firstName,lastName];
}
UIImage *image = [UIImage imageWithData:contact.imageData];
if (image != nil) {
profileImage = image;
}else{
profileImage = [UIImage imageNamed:@"person-icon.png"];
}
for (CNLabeledValue *label in contact.phoneNumbers) {
phone = [label.value stringValue];
if ([phone length] > 0) {
[contactNumbersArray addObject:phone];
}
}
NSDictionary* personDict = [[NSDictionary alloc] initWithObjectsAndKeys: fullName,@"fullName",profileImage,@"userImage",phone,@"PhoneNumbers", nil];
[MutableArray__Contact addObject:personDict];
}
dispatch_async(dispatch_get_main_queue(), ^
{
NSLog(@"%@",ar_Contact);
//[self.tableViewRef reloadData];
});
}
}
}];
}
用于使用此方法调用contactsFromAddressBook函数
[self contactsFromAddressBook];
联系人权限iOS 9 SWIFT 2
let status : CNAuthorizationStatus = CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts)
if status == CNAuthorizationStatus.NotDetermined{
contactStore.requestAccessForEntityType(CNEntityType.Contacts, completionHandler: { (temp: Bool, error : NSError?) -> Void in
//call contacts fetching function
})
}else if status == CNAuthorizationStatus.Authorized {
//call contacts fetching function
})
}
else if status == CNAuthorizationStatus.Denied {
}
}
这里是swift 3.0的flohei's answer版本>
lazy var contacts: [CNContact] = { let contactStore = CNContactStore() let keysToFetch = [ CNContactFormatter.descriptorForRequiredKeys(for: .fullName), CNContactPostalAddressesKey, CNContactEmailAddressesKey, CNContactPhoneNumbersKey, CNContactImageDataAvailableKey, CNContactThumbnailImageDataKey] as [Any] // Get all the containers var allContainers: [CNContainer] = [] do { allContainers = try contactStore.containers(matching: nil) } catch { print("Error fetching containers") } var results: [CNContact] = [] // Iterate all containers and append their contacts to our results array for container in allContainers { let fetchPredicate = CNContact.predicateForContactsInContainer(withIdentifier: container.identifier) do { let containerResults = try contactStore.unifiedContacts(matching: fetchPredicate, keysToFetch: keysToFetch as! [CNKeyDescriptor]) results.append(contentsOf: containerResults) } catch { print("Error fetching results for container") } } return results }()希望这会有所帮助！
只想分享此版本的Swift 4
[@ flohei
Objective-C：
//ios 9+
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(@"error fetching contacts %@", error);
} else {
for (CNContact *contact in cnContacts) {
// copy data to my custom Contacts class.
Contact *newContact = [[Contact alloc] init];
newContact.firstName = contact.givenName;
newContact.lastName = contact.familyName;
UIImage *image = [UIImage imageWithData:contact.imageData];
newContact.image = image;
for (CNLabeledValue *label in contact.phoneNumbers) {
NSString *phone = [label.value stringValue];
if ([phone length] > 0) {
[contact.phones addObject:phone];
}
}
}
}
}
}];
也可以使用enumerateContactsWithFetchRequest方法获取所有联系人：
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
NSError *error;
BOOL success = [store enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact * __nonnull contact, BOOL * __nonnull stop) {
if (error) {
NSLog(@"error fetching contacts %@", error);
} else {
// copy data to my custom Contact class.
Contact *newContact = [[Contact alloc] init];
newContact.firstName = contact.givenName;
newContact.lastName = contact.familyName;
// etc.
}
}];
}
}];
如果要按姓名过滤联系人，可以使用此：
Obj-C：
// keys from example above
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:[CNContact predicateForContactsMatchingName:@"John Appleseed"] keysToFetch:keys error:&error];
Swift 3：
let store = CNContactStore()
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingName("Appleseed"), keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey])
使用Swift和Contacts框架来获取所有联系人，包括姓名和电话号码
import Contacts
let store = CNContactStore()
store.requestAccessForEntityType(.Contacts, completionHandler: {
granted, error in
guard granted else {
let alert = UIAlertController(title: "Can't access contact", message: "Please go to Settings -> MyApp to enable contact permission", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
return
}
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName), CNContactPhoneNumbersKey]
let request = CNContactFetchRequest(keysToFetch: keysToFetch)
var cnContacts = [CNContact]()
do {
try store.enumerateContactsWithFetchRequest(request){
(contact, cursor) -> Void in
cnContacts.append(contact)
}
} catch let error {
NSLog("Fetch contact error: \(error)")
}
NSLog(">>>> Contact list:")
for contact in cnContacts {
let fullName = CNContactFormatter.stringFromContact(contact, style: .FullName) ?? "No Name"
NSLog("\(fullName): \(contact.phoneNumbers.description)")
}
})
获取联系人是慢操作，因此您不应阻止主UI线程。在后台线程上执行CNContactFetchRequest。这就是为什么我将代码放入completionHandler。它在后台线程上运行。
Apple实际上建议CNContactStore的enumerateContactsWithFetchRequest来获取所有联系人和NOT UnifiedContactsMatchingPredicate。
下面是Obj-C的工作代码。
CNContactStore *store = [[CNContactStore alloc] init];
//keys with fetching properties
NSArray *keys = @[CNContactGivenNameKey, CNContactPhoneNumbersKey];
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
NSError *error;
[store enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact * __nonnull contact, BOOL * __nonnull stop) {
// access it this way -> contact.givenName; etc
}];
这里是苹果建议枚举功能的链接：https://developer.apple.com/reference/contacts/cncontactstore/1403266-unifiedcontactsmatchingpredicate?language=objc#discussion
如果链接过期，这是苹果写的：
如果未找到匹配项，则此方法返回一个空数组（或nil in错误的情况）。仅使用CNContact类中的谓词谓词。此方法不支持复合谓词。到期为了统一，返回的联系人可能具有不同的标识符比您指定的要多。 获取所有联系人，使用
enumerateContactsWithFetchRequest:error:usingBlock:。
对于Swift 4
var results: [CNContact] = []
let fetchRequest = CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey as CNKeyDescriptor, CNContactFamilyNameKey as CNKeyDescriptor, CNContactMiddleNameKey as CNKeyDescriptor, CNContactEmailAddressesKey as CNKeyDescriptor,CNContactPhoneNumbersKey as CNKeyDescriptor])
fetchRequest.sortOrder = CNContactSortOrder.userDefault
let store = CNContactStore()
do {
try store.enumerateContacts(with: fetchRequest, usingBlock: { (contact, stop) -> Void in
print(contact.phoneNumbers.first?.value ?? "no")
results.append(contact)
})
}
catch let error as NSError {
print(error.localizedDescription)
}
旧版本对于快速var结果包含所有联系人
let contactStore = CNContactStore()
var results: [CNContact] = []
do {
try contactStore.enumerateContactsWithFetchRequest(CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactMiddleNameKey, CNContactEmailAddressesKey,CNContactPhoneNumbersKey])) {
(contact, cursor) -> Void in
results.append(contact)
}
}
catch{
print("Handle the error please")
}

@@ rocolitis的回答很快！根据苹果的文档，他的答案是最正确的方法。
let contactStore = CNContactStore()
let keys = [CNContactPhoneNumbersKey, CNContactFamilyNameKey, CNContactGivenNameKey, CNContactNicknameKey] as [CNKeyDescriptor]
let request = CNContactFetchRequest(keysToFetch: keys)
try? contactStore.enumerateContacts(with: request) { (contact, error) in
// Do something with contact
}
您可能应该先检查对联系人的访问权限！
let authorization = CNContactStore.authorizationStatus(for: CNEntityType.contacts)
switch authorization {
case .authorized: break
case .denied: break
case .restricted: break
case .notDetermined: break
}
首先获取默认容器标识符并使用谓词匹配容器标识符
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey]
let containerId = CNContactStore().defaultContainerIdentifier()
let predicate: NSPredicate = CNContact.predicateForContactsInContainerWithIdentifier(containerId)
let contacts = try CNContactStore().unifiedContactsMatchingPredicate(predicate, keysToFetch: keysToFetch)
