功能描述

XGAssetPickerController是一款iOS相册选择器，支持图片、视频拍摄，多图片、多视频混选及预览， 支持Gif浏览(iOS11+)，多个相册目录同一图片/视频可自动排重，并具有记录已选图片/视频的功能。

系统要求

该项目最低支持 iOS 8.0+。

演示项目

1. 命令行进入Demo文件夹路径下，并执行pod install
2. 打开XGAssetPickerController-Demo.xcworkspace

安装

CocoaPods

1. 在 Podfile 中添加 pod 'XGAssetPickerController'。
2. 执行 pod install 或 pod update。
3. #import "XG_AssetPickerController.h"

手动安装

1. 下载 XGAssetPickerController 文件夹内的所有内容。
2. 将 XGAssetPickerController 内的源文件添加(拖放)到你的工程。
3. 由于用到了FLAnimatedImage，所以需要下载FLAnimatedImage（https://github.com/Flipboard/FLAnimatedImage），并添加(拖放)到你的工程。
4. #import "XG_AssetPickerController.h".

使用方法

1. 先使用[[XG_AssetPickerManager manager] handleAuthorizationWithCompletion:^(XG_AuthorizationStatus aStatus) { }];检查是否获取相册权限，然后根据XG_AuthorizationStatus做进一步处理

2. 初始化XG_AssetPickerOptions对象来配置选择器，maxAssetsCount表示最大可选择数量，videoPickable表示是否可选择视频，已选的图片或者视频会保存在pickedAssetModels数组中。

3. 使用初始化选择器XG_AssetPickerController，然后 UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:photoPickerVc]; [self presentViewController:nav animated:YES completion:nil];

4. 遵循<XG_AssetPickerControllerDelegate>协议，并实现协议方法： - (void)assetPickerController:(XG_AssetPickerController *)picker didFinishPickingAssets:(NSArray<XG_AssetModel *> *)assets;，选择结果在参数assets中。

   具体使用方法可参见示例Demo

注意事项

1. 如果运行崩溃,崩溃信息log为：This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryUsageDescription/NSCameraUsageDescription key with a string value explaining to the user how the app uses this data. 请检查Info.plist是否添加相册/相机权限: NSPhotoLibraryUsageDescription/NSCameraUsageDescription

2. 模拟器环境下，虽然在工程的Localizations配置中添加了简体中文Chinese（Simplified）,但相册名称仍会默认为英文，这是正常的，因为Localizations在真机环境下才会生效（即真机环境下相册名称会显示成中文）。
