Adapted to iOS8 or above，Use Photos framework to get all the album pictures or video, save the picture to the system album or save to the custom album, delete a custom photo album, etc.; 适应于iOS8以上 ，运用Photos 框架 获取所有相册图片或视频，保存图片到系统相册或同时保存到自定义相册，单独删除某自定义相册的图片等； 接口如下：/**
- 获取相册权限 */
- (void)getRequestAuthorizationWithHandleBlock:(StatusBlock)handleBlock; /**
- createdAssetId
- @param image 要保存的图片
- @return createdAssetId 图片ID */
- (NSString*)createdAssetIdWithImage:(UIImage*)image; /**
- 只在系统相册里添加图片
- @param createdAssetId 图片ID
- @return 保存图片 */ -(PHFetchResult<PHAsset *> )createdAssetsWithCreatedAssetId:(NSString)createdAssetId;
/**
- createdCollectionId
- @param title 自定义相册名称
- @return createdCollectionId 相册ID */
- (NSString*)createdCollectionIdWithTitle:(NSString*)title; /**
- createdCollection
- @param title 自定义相册名称
- @return createdCollection 自定义相册 */ -(PHAssetCollection )createdCollectionWithTilte:(NSString )title;
/**
- 保存图片到相册和自定义相册
- @param image 保存的图片
- @param createdCollectionTitle 自定义相册名称 / -(void)saveImageIntoAlbumWithImage:(UIImage)image CreatedCollectionTitle:(NSString* )createdCollectionTitle;
/**
- 获取所有的图片或视频 */
- (void)getAllImagesOrVideosWithMediaType:(PHAssetMediaType)mediaType; /**
- 获取某个相册里面的所有图片或视频的相关数据 */
- (NSArray*)getAllImagesOrVideosInCollection:(PHAssetCollection *)collection MediaType:(PHAssetMediaType)mediaType;
//删除自定义相册里的图片
- (void)deletePhotoFormCollection:(PHAssetCollection*)collection; /**
- 获取所有图片或视频resultBlock
- @param resultBlock ResultBlock */
- (void)getResultWithResultBlock:(ResultBlock)resultBlock;
DemoCode below: #import "DemoViewController.h" #import "GFPhotos.h" @interface DemoViewController () @property (weak, nonatomic) IBOutlet UIImageView imageView; @property (nonatomic,strong) GFPhotos photo; @end
@implementation DemoViewController
- (void)viewDidLoad { [super viewDidLoad]; //1.创建Photos实例 GFPhotos* photo = [[GFPhotos alloc]init]; self.photo = photo;
}
- (IBAction)saveImageOnlyToSystemCollection:(id)sender { [self saveImageOnlyToSystemCollectionWithImage:self.imageView.image];
}
-
(IBAction)saveImageBothToCustomCollection:(id)sender {
[self saveImageBothToCustomCollectionWithImage:self.imageView.image Title:@"新相册"];
}
-
(IBAction)getAllPhotos:(id)sender { //2.获取所有图片或视频 [self.photo getAllImagesOrVideosWithMediaType:PHAssetMediaTypeImage]; //3.获取resultBlock [self.photo getResultWithResultBlock:^(NSArray *allPhotos, NSArray *allVideos) { NSLog(@"allphotos:%@",allPhotos);
}];
}
- (IBAction)deleteLastPhotoInCollection:(id)sender { [self deleteLastPhotoInCollectionWithTitle:@"新相册"];
}
-
(IBAction)getAllVideos:(id)sender { [self.photo getAllImagesOrVideosWithMediaType:PHAssetMediaTypeVideo]; [self.photo getResultWithResultBlock:^(NSArray *allPhotos, NSArray *allVideos) { NSLog(@"allVideo:%@",allVideos);
}]; } #pragma mark-------- 只在系统相册创建添加照片
-
(void)saveImageOnlyToSystemCollectionWithImage:(UIImage*)image{ [self.photo getRequestAuthorizationWithHandleBlock:^(PHAuthorizationStatus status) { if (status != PHAuthorizationStatusAuthorized) { return ; }
[self.photo createdAssetsWithCreatedAssetId:[self.photo createdAssetIdWithImage:image]];}];
} #pragma mark---------在系统相册和自定义相册里都添加照片
-
(void)saveImageBothToCustomCollectionWithImage:(UIImage*)image Title:(NSString* )title{
[self.photo getRequestAuthorizationWithHandleBlock:^(PHAuthorizationStatus status) { if (status != PHAuthorizationStatusAuthorized) { return ; }
[self.photo saveImageIntoAlbumWithImage:image CreatedCollectionTitle:title];}];
} #pragma mark-------删除某自定义相册的最后一张图片
- (void)deleteLastPhotoInCollectionWithTitle:(NSString* )title{ [self.photo getRequestAuthorizationWithHandleBlock:^(PHAuthorizationStatus status) { if (status != PHAuthorizationStatusAuthorized) { return ; } [self.photo deletePhotoFormCollection:[self.photo createdCollectionWithTilte:title]]; }];
