因项目后期可能需要备份通讯录和相册，趁现在时间多，提前先了解下写个Demo。关于Contacts也有官方的视频，但视频是用Swift写的，让我也觉得要快速入手Swift了。
通讯录
通讯录要先导入�#import <Contacts/Contacts.h>
添加联系人(由于我主要做备份，就写死了)
CNMutableContact * contact = [[CNMutableContact alloc]init];
contact.imageData = UIImagePNGRepresentation([UIImage imageNamed:@"naruto.jpg"]);
contact.givenName = @"steven";//设置名字
contact.familyName = @"guo";//设置姓氏
contact.emailAddresses = @[[CNLabeledValue labeledValueWithLabel:CNLabelWork value:@"956995511@qq.com"]];//邮箱
contact.phoneNumbers = @[[CNLabeledValue labeledValueWithLabel:CNLabelPhoneNumberiPhone value:[CNPhoneNumber phoneNumberWithStringValue:@"13999999999"]]];//电话
/*其余属性我就不配置了
@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，未完。。。
*/
//地址
CNMutablePostalAddress * homeAdress = [[CNMutablePostalAddress alloc]init];
homeAdress.street = @"大街";
homeAdress.city = @"深圳";
homeAdress.state = @"中国";
homeAdress.postalCode = @"518000";
contact.postalAddresses = @[[CNLabeledValue labeledValueWithLabel:CNLabelHome value:homeAdress]];
//生日
NSDateComponents * birthday = [[NSDateComponents alloc]init];
birthday.day=4;
birthday.month=2;
birthday.year=1989;
contact.birthday=birthday;
CNSaveRequest * saveRequest = [[CNSaveRequest alloc]init];
//将创建的联系人添加到系统通讯录中
[saveRequest addContact:contact toContainerWithIdentifier:nil];
/*方法也有很多
//添加一个联系人
- (void)addContact:(CNMutableContact *)contact toContainerWithIdentifier:(nullable NSString *)identifier;
//更新一个联系人
- (void)updateContact:(CNMutableContact *)contact;
//删除一个联系人
- (void)deleteContact:(CNMutableContact *)contact;
//添加一组联系人
- (void)addGroup:(CNMutableGroup *)group toContainerWithIdentifier:(nullable NSString *)identifier;
//更新一组联系人
- (void)updateGroup:(CNMutableGroup *)group;
//删除一组联系人
- (void)deleteGroup:(CNMutableGroup *)group;
//向组中添加子组
- (void)addSubgroup:(CNGroup *)subgroup toGroup:(CNGroup *)group NS_AVAILABLE(10_11, NA);
//在组中删除子组
- (void)removeSubgroup:(CNGroup *)subgroup fromGroup:(CNGroup *)group NS_AVAILABLE(10_11, NA);
//向组中添加成员
- (void)addMember:(CNContact *)contact toGroup:(CNGroup *)group;
//向组中移除成员
- (void)removeMember:(CNContact *)contact fromGroup:(CNGroup *)group;
*/
CNContactStore * store = [[CNContactStore alloc]init];
[store executeSaveRequest:saveRequest error:nil];//保存前面创建的请求
跳转至系统通讯录
需导入#import <ContactsUI/ContactsUI.h>
CNContactPickerViewController * contactVC = [[CNContactPickerViewController alloc]init];
[self presentViewController:contactVC animated:YES completion:nil];
比起之前的AddressBookFramework，这个简单的不要不要的。。。
规档
CNContactStore * stroe = [[CNContactStore alloc]init];
CNContactFetchRequest * request = [[CNContactFetchRequest alloc]initWithKeysToFetch:@[CNContactIdentifierKey,CNContactFamilyNameKey,CNContactGivenNameKey,CNContactOrganizationNameKey,CNContactPhoneNumbersKey,CNContactEmailAddressesKey,CNContactPostalAddressesKey,CNContactImageDataKey]];
NSMutableArray * arr = [@[] mutableCopy];
[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"];//规档到桌面
详细的可以看Demo.
相册
跳转至系统相册
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
[self presentViewController:picker animated:YES completion:nil];
备份相册
使用Photos框架，先#import <Photos/Photos.h>
NSMutableArray *dataArray = [NSMutableArray array];
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc]init];
PHFetchResult *smartAlbumsFetchResult = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeSmartAlbumUserLibrary options:fetchOptions];
/*第一个参数的枚举含义
PHAssetCollectionTypeAlbum //从 iTunes 同步来的相册，以及用户在 Photos 中自己建立的相册
PHAssetCollectionTypeSmartAlbum //经由相机得来的相册
PHAssetCollectionTypeMoment //Photos 为我们自动生成的时间分组的相册
*/
/*第二个参数的枚举含义
PHAssetCollectionSubtypeAlbumRegular //用户在 Photos 中创建的相册，也就是我所谓的逻辑相册
PHAssetCollectionSubtypeAlbumSyncedEvent //使用 iTunes 从 Photos 照片库或者 iPhoto 照片库同步过来的事件。然而，在iTunes 12 以及iOS 9.0 beta4上，选用该类型没法获取同步的事件相册，而必须使用AlbumSyncedAlbum。
PHAssetCollectionSubtypeAlbumSyncedFaces //使用 iTunes 从 Photos 照片库或者 iPhoto 照片库同步的人物相册。
PHAssetCollectionSubtypeAlbumSyncedAlbum //做了 AlbumSyncedEvent 应该做的事
PHAssetCollectionSubtypeAlbumImported //从相机或是外部存储导入的相册.
PHAssetCollectionSubtypeAlbumMyPhotoStream //用户的 iCloud 照片流
PHAssetCollectionSubtypeAlbumCloudShared //用户使用 iCloud 共享的相册
PHAssetCollectionSubtypeSmartAlbumGeneric //文档解释为非特殊类型的相册，主要包括从 iPhoto 同步过来的相册。
PHAssetCollectionSubtypeSmartAlbumPanoramas //相机拍摄的全景照片
PHAssetCollectionSubtypeSmartAlbumVideos //相机拍摄的视频
PHAssetCollectionSubtypeSmartAlbumFavorites //收藏文件夹
PHAssetCollectionSubtypeSmartAlbumTimelapses //延时视频文件夹，同时也会出现在视频文件夹中
PHAssetCollectionSubtypeSmartAlbumAllHidden //包含隐藏照片或视频的文件夹
PHAssetCollectionSubtypeSmartAlbumRecentlyAdded //相机近期拍摄的照片或视频
PHAssetCollectionSubtypeSmartAlbumBursts //连拍模式拍摄的照片，在 iPad mini 上按住快门不放就可以了，但是照片依然没有存放在这个文件夹下，而是在相机相册里。
PHAssetCollectionSubtypeSmartAlbumSlomoVideos //Slomo 是 slow motion 的缩写，高速摄影慢动作解析，在该模式下，iOS 设备以120帧拍摄。不过我的 iPad mini 不支持，没法验证。
PHAssetCollectionSubtypeSmartAlbumUserLibrary //相机相册，所有相机拍摄的照片或视频都会出现在该相册中，而且使用其他应用保存的照片也会出现在这里。
PHAssetCollectionSubtypeAny //包含所有类型
*/
//这里说明一下，必须要同步执行。。。否则你还没遍历完图片就规档完了
dispatch_async(dispatch_get_global_queue(0, 0), ^{
//遍历相机胶卷
[smartAlbumsFetchResult enumerateObjectsUsingBlock:^(PHAssetCollection * _Nonnull collection, NSUInteger idx, BOOL *stop) {
if (![collection.localizedTitle isEqualToString:@"Videos"]) {
NSArray<PHAsset *> *assets = [self GetAssetsInAssetCollection:collection];
for (PHAsset * asset in assets) {
[[PHImageManager defaultManager]requestImageDataForAsset:asset options:nil resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
[dataArray addObject:imageData];
}];
}
}
}];
//遍历自定义相册
PHFetchResult *smartAlbumsFetchResult1 = [PHAssetCollection fetchTopLevelUserCollectionsWithOptions:fetchOptions];
[smartAlbumsFetchResult1 enumerateObjectsUsingBlock:^(PHAssetCollection * _Nonnull collection, NSUInteger idx, BOOL *stop) {
NSArray<PHAsset *> *assets = [self GetAssetsInAssetCollection:collection];
for (PHAsset * asset in assets) {
[[PHImageManager defaultManager]requestImageDataForAsset:asset options:nil resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
[dataArray addObject:imageData];
}];
}
}];
[dataArray writeToFile:@"/Users/Crazy_Steven/Desktop/Photos.plist" atomically:YES];
});
- (NSArray *)GetAssetsInAssetCollection:(PHAssetCollection *)assetCollection
{
NSMutableArray<PHAsset *> *arr = [NSMutableArray array];
PHFetchResult *result = [self GetFetchResult:assetCollection];
[result enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
if (((PHAsset *)obj).mediaType == PHAssetMediaTypeImage) {
[arr addObject:obj];
}
}];
return arr;
}
-(NSString *) FormatPhotoAlumTitle:(NSString *)title
{
if ([title isEqualToString:@"All Photos"] || [title isEqualToString:@"Camera Roll"]) {
return @"相机胶卷";
}
return nil;
}
-(PHFetchResult *)GetFetchResult:(PHAssetCollection *)assetCollection
{
PHFetchResult *fetchResult = [PHAsset fetchAssetsInAssetCollection:assetCollection options:nil];
return fetchResult;
}
具体效果还是看Demo,和通讯录的写到一起了，用的方法比较Low,不知道百度之类的云盘是怎么实现备份的，知道的也请大家告诉我，一同进步。。。
