17 | 18 | ## 使用方式 19 | 20 | 详情见`demo`查看 21 | 22 | ### 相册获取方式 23 | 24 | | 属性 | 说明 | 25 | | --- | --- | 26 | | **Controller** | | 27 | | XYPhotoMultiImagePicker | NavigationController,承载两个VC栈、相册相关参数初始化工作及 delegate & datasource | 28 | | XYPhotoAlbumListController | 系统和用户的相册列表（tableview），根据CLPhotoMultiPickerStartPosition来确定初始展示哪个VC界面 | 29 | | XYPhotoAlbumDetailController | 某个相册的详情（collectionView），单选多选照片的不同交互主要完成于此，可进入大图预览 | 30 | | XYPhotoPreviewViewController | 大图预览（XYHorizontalScrollView）| 31 | 32 | ### 用法 33 | 34 | ```objc 35 | 36 | XYPhotoMultiImagePicker *multiImagePicker = [[XYPhotoMultiImagePicker alloc] init]; 37 | multiImagePicker.pickerDelegate = self; 38 | multiImagePicker.pickerDataSource = self; 39 | multiImagePicker.mediaType = PHAssetMediaTypeImage; // 支持图片和视屏 40 | multiImagePicker.maxNumberOfAssets = 9; // 最多选择九张照片 41 | multiImagePicker.assetCollectionViewColumnCount = 4; // 获取 42 | multiImagePicker.startPosition = CLPhotoMultiPickerStartPositionAlbums; // 相册列表开始进入 43 | multiImagePicker.allowNetRequestIfiCloud = YES; // 支持iCloud网络获取 44 | [self presentViewController:multiImagePicker animated:YES completion:nil]; 45 | 46 | 47 | #pragma mark - XYPhotoMultiImagePickerDelegate, XYPhotoMultiImagePickerDataSource 48 | 49 | - (void)multiImagePicker:(XYPhotoMultiImagePicker *)multiImagePicker selectedAssets:(NSArray *)assets 50 | { 51 | _selectedAssets = assets;

77 | camera.pickerDelegate = self; 78 | camera.pickerDataSource = self; 79 | camera.maxNumberOfAssets = 9; // 最多选择九张照片 80 | camera.allowNetRequestIfiCloud = YES; // 支持iCloud网络获取 81 | [self presentViewController:camera animated:YES completion:nil];

107 | options.networkAccessAllowed = YES; 108 | 109 | _imageRequestId = [self.imageManager requestImageForAsset:asset 110 | targetSize:_targetSize 111 | contentMode:PHImageContentModeAspectFit 112 | options:options 113 | resultHandler:^(UIImage *result, NSDictionary *info) { 114 | BOOL downloadFinined = ![[info objectForKey:PHImageCancelledKey] boolValue] 115 | && ![info objectForKey:PHImageErrorKey] 116 | && ![[info objectForKey:PHImageResultIsDegradedKey] boolValue];
