iOS：基于Photos框架的图片选择器以及创建自定义相册

MMPhotoPicker（下载链接）基于Photos框架，集成了图片选择器（支持多选、单选、对图片进行裁剪、选择原图、可预览）以及创建自定义相册，并保存图片到自定义相册。若想使用基于AssetsLibrary框架的图片选择器，点击这里。

使用

1. pod "MMPhotoPicker" ;
2. pod install / pod update;
3. #import <MMPhotoPicker/MMPhotoPickerController.h>.

MMPhotoPickerController属性介绍：// 主色调[默认蓝色]@property (nonatomic, strong) UIColor *mainColor;// 是否回传原图 [可用于控制图片压系数]@property (nonatomic, assign) BOOL isOrigin;// 是否显示原图选项 [默认NO]@property (nonatomic, assign) BOOL showOriginImageOption;// 是否显示空相册 [默认NO]@property (nonatomic, assign) BOOL showEmptyAlbum;// 是否只选取一张 [默认NO]@property (nonatomic, assign) BOOL singleImageOption;// 是否选取一张且需要裁剪 [默认NO]@property (nonatomic, assign) BOOL cropImageOption;// 裁剪的大小[默认方形、屏幕宽度]@property (nonatomic, assign) CGSize imageCropSize;// 最大选择数目[默认9张]@property (nonatomic, assign) NSInteger maximumNumberOfImage;// 代理@property (nonatomic, assign) id<MMPhotoPickerDelegate> delegate;

图片选择

MMPhotoPickerController *mmVC = [[MMPhotoPickerController alloc] init];// 设置代理mmVC.delegate = self;// 设置显示空相册mmVC.showEmptyAlbum = YES;// 设置最大选择数目mmVC.maximumNumberOfImage = 9;UINavigationController *mmNav = [[UINavigationController alloc] initWithRootViewController:mmVC];[self.navigationController presentViewController:mmNav animated:YES completion:nil];

#pragma mark - MMPhotoPickerDelegate- (void)mmPhotoPickerController:(MMPhotoPickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info{     NSLog(@"%@",info);}- (void)mmPhotoPickerControllerDidCancel:(MMPhotoPickerController *)picker{     NSLog(@"Cancel");}

保存视频/图片到自定义相册

MMPhotoUtil类中：// 图片+ (void)writeImageToPhotoAlbum:(UIImage *)image;// 视频+ (void)writeVideoToPhotoAlbum:(NSURL *)videoURL;

注意

1. 需要在Info.plist中添加隐私授权：Privacy - Photo Library Usage Description；
2. 如果相册名称需要根据手机语言环境显示相应语言，需要在Info.plist中设置Localized resources can be mixed 为 YES。
