因項(xiàng)目后期可能需要備份通訊錄和相冊媳荒，趁現(xiàn)在時(shí)間多，提前先了解下寫個(gè)Demo貌夕。關(guān)于Contacts也有官方的視頻磷籍，但視頻是用Swift寫的闷哆，讓我也覺得要快速入手Swift了站楚。
通訊錄
通訊錄要先導(dǎo)入?#import <Contacts/Contacts.h>
添加聯(lián)系人(由于我主要做備份，就寫死了)
CNMutableContact * contact = [[CNMutableContact alloc]init];
contact.imageData = UIImagePNGRepresentation([UIImage imageNamed:@"naruto.jpg"]);
contact.givenName = @"steven";//設(shè)置名字
contact.familyName = @"guo";//設(shè)置姓氏
contact.emailAddresses = @[[CNLabeledValue labeledValueWithLabel:CNLabelWork value:@"956995511@qq.com"]];//郵箱
contact.phoneNumbers = @[[CNLabeledValue labeledValueWithLabel:CNLabelPhoneNumberiPhone value:[CNPhoneNumber phoneNumberWithStringValue:@"13999999999"]]];//電話
/*其余屬性我就不配置了
@property (copy, NS_NONATOMIC_IOSONLY) NSString *namePrefix;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *givenName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *middleName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *familyName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *previousFamilyName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *nameSuffix;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *nickname;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *phoneticGivenName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *phoneticMiddleName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *phoneticFamilyName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *organizationName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *departmentName;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *jobTitle;
@property (copy, NS_NONATOMIC_IOSONLY) NSString *note;
太多了轻绞，未完采记。。政勃。

需導(dǎo)入#import <ContactsUI/ContactsUI.h>
CNContactPickerViewController * contactVC = [[CNContactPickerViewController alloc]init];
[self presentViewController:contactVC animated:YES completion:nil];
比起之前的AddressBookFramework唧龄，這個(gè)簡單的不要不要的。奸远。既棺。
規(guī)檔
CNContactStore * stroe = [[CNContactStore alloc]init];
CNContactFetchRequest * request = [[CNContactFetchRequest alloc]initWithKeysToFetch:@[CNContactIdentifierKey,CNContactFamilyNameKey,CNContactGivenNameKey,CNContactOrganizationNameKey,CNContactPhoneNumbersKey,CNContactEmailAddressesKey,CNContactPostalAddressesKey,CNContactImageDataKey]];

[stroe enumerateContactsWithFetchRequest:request error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {
[arr addObject:contact];
}];
[NSKeyedArchiver archiveRootObject:arr toFile:@"/Users/Crazy_Steven/Desktop/contact.xml"];//規(guī)檔到桌面
詳細(xì)的可以看Demo.
相冊
跳轉(zhuǎn)至系統(tǒng)相冊

具體效果還是看Demo,和通訊錄的寫到一起了莹弊，用的方法比較Low,不知道百度之類的云盤是怎么實(shí)現(xiàn)備份的，知道的也請大家告訴我涡尘，一同進(jìn)步忍弛。。考抄。
