如何使用联系人框架获取 iOS 9 中的所有联系人记录

Question

AddressBook 框架的大部分内容在 iOS 9 中已弃用。在新的联系人框架中 documentation 仅显示如何获取记录匹配 NSPredicate，但如果我想要全部条记录?

Answer 1

先获取默认容器标识符，然后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)

Answer 2

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];
                    }
                }
            }
        }
    }        
}];

还可以使用 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.
            }
        }];
    }        
}];

如果您想按姓名过滤联系人，您可以使用：

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])

Answer 3

其他两个答案都只从带有 defaultContainerIdentifier 的容器中加载联系人。在一种情况下，用户有多个容器（即 Exchange 和 iCloud 帐户都用于存储联系人），这只会从配置为默认的帐户加载联系人。因此，它不会按照问题作者的要求加载 all 个联系人。

您可能想要做的是获取所有容器并迭代它们以从每个容器中提取所有联系人。以下代码片段是我们如何在我们的一个应用程序中执行此操作的示例（在 Swift 中）：

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
}()

Answer 4

为Swift4

        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 swift 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")
    }

Answer 5

现在 iOS9 ABAddressBookRef 已弃用，因此要从 phone 获取所有联系人，请使用此框架并添加此功能，您将获得联系人数组。

像这样在 .h 中导入 Contact 框架 class

#import <Contacts/Contacts.h>

然后在.m文件中添加这个方法

 -(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];
            });
        }
    }
}];
}

使用此方法调用 contactsFromAddressBook 函数

[self contactsFromAddressBook];

                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];
                [arrayTableData addObject:[NSString stringWithFormat:@"%@",[personDict objectForKey:@"fullName"]]];
                NSLog(@"The contactsArray are - %@",arrayTableData);
            }
            dispatch_async(dispatch_get_main_queue(), ^{
                [tableViewContactData reloadData];
            });
        }
    }
}];
}
@end

输出为

The contactsArray are - (
"John Appleseed",
"Kate Bell",
"Anna Haro",
"Daniel Higgins",
"David Taylor",
"Hank Zakroff"
}

使用Swift和联系人框架获取所有联系人，包括姓名和phone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，因此您不应阻塞主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 中的原因。它在后台线程上运行。

SWIFT 2

从 iOS9

中的联系人框架中获取全名、电子邮件 ID、Phone 号码、个人资料图片

注意没有姓名的联系人也已处理。

            })
        }
        else if status == CNAuthorizationStatus.Denied {
            }
    }

Answer 11

Apple 实际上推荐使用 CNContactStore 的 enumerateContactsWithFetchRequest 来获取所有联系人，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

}];

这里是苹果推荐的link枚举函数： https://developer.apple.com/reference/contacts/cncontactstore/1403266-unifiedcontactsmatchingpredicate?language=objc#discussion

如果 link 已过期，Apple 是这样写的：

If no matches are found, this method returns an empty array (or nil in case of error). Use only the predicates from the CNContact class predicates. Compound predicates are not supported by this method. Due to unification, the returned contacts may have different identifiers than you specify. To fetch all contacts, use enumerateContactsWithFetchRequest:error:usingBlock:.

Answer 12

@rocolitis 在 swift 中的回答！根据 Apple 的文档，他的回答是最正确的做法。

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

}

您可能应该先检查您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
}

Answer 13

在swift 3 and Xcode 8你可以得到所有联系人列表

let keys = [CNContactGivenNameKey ,CNContactImageDataKey,CNContactPhoneNumbersKey]
        var message: String!
        //let request=CNContactFetchRequest(keysToFetch: keys)
        let contactsStore = AppDelegate.AppDel.contactStore
        // Get all the containers
        var allContainers: [CNContainer] = []
        do {
            allContainers = try contactsStore.containers(matching: nil)
        } catch {
            print("Error fetching containers")
        }



        // 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 contactsStore.unifiedContacts(matching: fetchPredicate, keysToFetch: keys as [CNKeyDescriptor])
                self.results.append(contentsOf: containerResults)
                self.tableView.reloadData()
                message="\(self.results.count)"
            } catch {
                print("Error fetching results for container")
            }
        }

Answer 14

我正在尝试这段代码，它工作正常。我可以使用联系人在 swift3 最新框架中使用此代码获取所有联系人详细信息：

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)
}

只是想分享这个版本的 Swift 4

info.plist:

<key>NSContactsUsageDescription</key>
    <string>$(PRODUCT_NAME) requires to access your contacts ...</string>

module:

import Contacts

code:

func fetchContacts(completion: @escaping (_ result: [CNContact]) -> Void){
        DispatchQueue.main.async {
            var results = [CNContact]()
            let keys = [CNContactGivenNameKey,CNContactFamilyNameKey,CNContactMiddleNameKey,CNContactEmailAddressesKey,CNContactPhoneNumbersKey] as [CNKeyDescriptor]
            let fetchRequest = CNContactFetchRequest(keysToFetch: keys)
            fetchRequest.sortOrder = .userDefault
            let store = CNContactStore()
            store.requestAccess(for: .contacts, completionHandler: {(grant,error) in
                if grant{
                    do {
                        try store.enumerateContacts(with: fetchRequest, usingBlock: { (contact, stop) -> Void in
                            results.append(contact)
                        })
                    }
                    catch let error {
                        print(error.localizedDescription)
                    }
                    completion(results)
                }else{
                    print("Error \(error?.localizedDescription ?? "")")
                }
            })
        }
    }

Usage:

fetchContacts(completion: {contacts in
            contacts.forEach({print("Name: \([=13=].givenName), number: \([=13=].phoneNumbers.first?.value.stringValue ?? "nil")")})

您需要先在info.plist中描述使用信息。我添加了一个检查以确定用户已授予对联系人的访问权限，然后定义了键（需要获取的值）。正如前面的一个答案所说，这是一个耗时的过程，所以我添加了 DispatchQueue 用于后台处理，并添加了 completion handler 用于返回联系人数组回到来电者。

如果您想获取具有已知标识符的联系人的所有字段：

let contact = unifiedContact(withIdentifier: identifier, keysToFetch: [CNContactVCardSerialization.descriptorForRequiredKeys()])

这使您可以访问所有字段，例如地址、phone 号码、全名等。

然后检索全名：

let fullname = CNContactFormatter.string(from: contact, style: .fullName)
