在iOS 9中不推荐使用AddressBook框架的大部分内容。新的联系人框架documentation仅显示如何获取与NSPredicate
匹配的记录,但如果我想要所有记录?
答案 0 :(得分:115)
其他两个答案都只会使用defaultContainerIdentifier
从容器中加载联系人。在用户具有多个容器(即,Exchange和iCloud帐户都用于存储联系人)的情况下,这将仅加载来自配置为默认帐户的联系人。因此,它不会按照问题作者的要求加载所有联系人。
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。以下代码段是我们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
}()

目标-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];
}
}
}
}
}
}];
同样要获取所有联系人,您可以使用enumerateContactsWithFetchRequest
方法:
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.
}
}];
}
}];
如果您想按名称过滤联系人,您可以使用:
的OBJ-C:
// keys from example above
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:[CNContact predicateForContactsMatchingName:@"John Appleseed"] keysToFetch:keys error:&error];

let store = CNContactStore()
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingName("Appleseed"), keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey])

使用 Swift 和联系人框架获取所有联系人,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,因此您不应该阻止主UI线程。在后台线程上执行CNContactFetchRequest
。这就是我将代码放入completionHandler的原因。它在后台线程上运行。

Apple实际上建议使用CNContactStore的enumerateContactsWithFetchRequest来获取所有联系人,并 NOT unifiedContactsMatchingPredicate。
以下是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
}];
以下是apple推荐枚举函数的链接: https://developer.apple.com/reference/contacts/cncontactstore/1403266-unifiedcontactsmatchingpredicate?language=objc#discussion
如果链接已过期,Apple写道:
如果未找到匹配项,则此方法返回一个空数组(或者为nil) 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。应有 为了统一,返回的联系人可以具有不同的标识符 比你指定的。 要获取所有联系人,请使用
enumerateContactsWithFetchRequest:error:usingBlock:
。

适用于Swift 4

fetchRequest.sortOrder = CNContactSortOrder.userDefault
let store = CNContactStore()
do {

print(contact.phoneNumbers.first?.value ?? "no")
results.append(contact)

}
catch let error as NSError {

@rocolitis迅速回答!根据Apple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
}
您可能应首先检查您对联系人的访问权限!

用法:

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,然后定义了密钥(需要获取的值)。正如前面的一个答案中所述,这是一个耗时的过程,因此我为后台处理添加了 DispatchQueue ,并将完成处理程序添加到了将联系人数组返回给调用者。

然后要检索全名:
let fullname = CNContactFormatter.string(from: contact, style: .fullName)
