1、系统通讯录的调用。这个比较简单，就是调用系统的UI，然后遵守CNContactPickerDelegate协议，里面有选中当前cell以及一些其他按钮的被点击触发的回调。
代码：
（1）调用系统控制器CNContactPickerViewController
let picker = CNContactPickerViewController()
picker.delegate = self //遵守CNContactPickerDelegate协议
self.present(picker, animated: true, completion: nil)
（2）实现协议方法，这里只写选中时调用的方法，还有一些比如取消按钮的回调，都在CNContactPickerDelegate协议里面
//实现CNContactPickerDelegate代理方法--可获得姓名，电话，邮箱等信息，所有可获取参数都在CNContact类中，具体Commond进去详查。
func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
print(contact.familyName) //姓
print(contact.givenName) //名
print(contact.phoneNumbers)//这里是电话号码的数组
for i in contact.phoneNumbers {
let phoneNum = i.value.stringValue //电话号码
print(phoneNum)
}
}
2.自定义通讯录
其实所谓自定义，就是我们需要拿到所有的通讯录数据然后进行重新布局。所以这里只贴出获取通讯录信息的类，这里摘自：http://www.hangge.com/blog/cache/detail_1523.html通信录获取联系人。只是对其代码中出现nil时作了一个简单的判断。直接贴代码吧。哦，这里还有一点，需要在info.plist文件里面设置通讯录访问权限。
import UIKit
import Contacts
class SelfAddressBook: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
CNContactStore().requestAccess(for: .contacts) { (isRight, error) in
if isRight {
//授权成功加载数据。
self.loadContactsData()
}
}
}
func loadContactsData() {
//获取授权状态
let status = CNContactStore.authorizationStatus(for: .contacts)
//判断当前授权状态
guard status == .authorized else { return }
//创建通讯录对象
let store = CNContactStore()
//获取Fetch,并且指定要获取联系人中的什么属性
let keys = [CNContactFamilyNameKey, CNContactGivenNameKey, CNContactNicknameKey,
CNContactOrganizationNameKey, CNContactJobTitleKey,
CNContactDepartmentNameKey, CNContactNoteKey, CNContactPhoneNumbersKey,
CNContactEmailAddressesKey, CNContactPostalAddressesKey,
CNContactDatesKey, CNContactInstantMessageAddressesKey
]
//创建请求对象，需要传入一个(keysToFetch: [CNKeyDescriptor]) 包含'CNKeyDescriptor'类型的数组
let request = CNContactFetchRequest(keysToFetch: keys as [CNKeyDescriptor])
//遍历所有联系人
do {
try store.enumerateContacts(with: request, usingBlock: {
(contact : CNContact, stop : UnsafeMutablePointer<ObjCBool>) -> Void in
//获取姓名
let lastName = contact.familyName
let firstName = contact.givenName
print("姓名：\(lastName)\(firstName)")
//获取昵称
let nikeName = contact.nickname
print("昵称：\(nikeName)")
//获取公司（组织）
let organization = contact.organizationName
print("公司（组织）：\(organization)")
//获取职位
let jobTitle = contact.jobTitle
print("职位：\(jobTitle)")
//获取部门
let department = contact.departmentName
print("部门：\(department)")
//获取备注
let note = contact.note
print("备注：\(note)")
//获取电话号码
print("电话：")
for phone in contact.phoneNumbers {
//获得标签名（转为能看得懂的本地标签名，比如work、home）
if phone.label != nil{
let label = CNLabeledValue<NSString>.localizedString(forLabel: phone.label!)
//获取号码
let value = phone.value.stringValue
print("\t\(label)：\(value)")
}
}
//获取Email
print("Email：")
for email in contact.emailAddresses {
if email.label != nil{
//获得标签名（转为能看得懂的本地标签名）
let label = CNLabeledValue<NSString>.localizedString(forLabel: email.label!)
//获取值
let value = email.value
print("\t\(label)：\(value)")
}
}
//获取地址
print("地址：")
for address in contact.postalAddresses {
if address.label != nil{
//获得标签名（转为能看得懂的本地标签名）
let label = CNLabeledValue<NSString>.localizedString(forLabel: address.label!)
//获取值
let detail = address.value
let contry = detail.value(forKey: CNPostalAddressCountryKey) ?? ""
let state = detail.value(forKey: CNPostalAddressStateKey) ?? ""
let city = detail.value(forKey: CNPostalAddressCityKey) ?? ""
let street = detail.value(forKey: CNPostalAddressStreetKey) ?? ""
let code = detail.value(forKey: CNPostalAddressPostalCodeKey) ?? ""
let str = "国家:\(contry) 省:\(state) 城市:\(city) 街道:\(street) 邮编:\(code)"
print("\t\(label)：\(str)")
}
}
//获取纪念日
print("纪念日：")
for date in contact.dates {
if date.label != nil{
//获得标签名（转为能看得懂的本地标签名）
let label = CNLabeledValue<NSString>.localizedString(forLabel: date.label!)
//获取值
let dateComponents = date.value as DateComponents
let value = NSCalendar.current.date(from: dateComponents)
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy年MM月dd日 HH:mm:ss"
print("\t\(label)：\(dateFormatter.string(from: value!))")
}
}
//获取即时通讯(IM)
print("即时通讯(IM)：")
for im in contact.instantMessageAddresses {
if im.label != nil{
//获得标签名（转为能看得懂的本地标签名）
let label = CNLabeledValue<NSString>.localizedString(forLabel: im.label!)
//获取值
let detail = im.value
let username = detail.value(forKey: CNInstantMessageAddressUsernameKey) ?? ""
let service = detail.value(forKey: CNInstantMessageAddressServiceKey) ?? ""
print("\t\(label)：\(username) 服务:\(service)")
}
}
print("----------------")
})

print(error)
