+## 注意事项
+
+#### 关于 3.x 版本 (使用 2.x 版本请切换到 store_2.x 分支)
+
+为了彻底解决 2.x 版本的设计缺陷和代码漏洞，特花费大量业余时间进行了 3.x 深度重构，所以没办法做到向下兼容，希望社区朋友们能体谅，根据情况进行版本迁移。
+3.x 版本有着更科学的架构，更极致的性能提升，更严格的内存控制，使用起来会更得心应手，也便于将来的迭代优化。
+
+#### 提问须知
+
+考虑到笔者的精力问题，遇到问题请先查看 API、效仿 Demo、阅读 README、搜索 Issues。请不要提出与组件无关的问题，比如 CocoaPods 的错误，如果是 BUG 或 Feature 最好是提 Issue。

+
+
+# 安装
+
+## CocoaPods
+
+支持分库导入，核心部分就是图片浏览功能，视频播放作为拓展功能按需导入。
+
+1. 在 Podfile 中添加：
+```
+pod 'YBImageBrowser'
+pod 'YBImageBrowser/Video'  //视频功能需添加
+```
+2. 执行 `pod install` 或 `pod update`。
+3. 导入 `<YBImageBrowser/YBImageBrowser.h>`，视频功能需导入`<YBImageBrowser/YBIBVideoData.h>`。
+4. 注意：如果你需要支持 WebP，可以在 Podfile 中添加 `pod 'YYImage/WebP'`。
+
+若搜索不到库，可执行`pod repo update`，或使用 `rm ~/Library/Caches/CocoaPods/search_index.json` 移除本地索引然后再执行安装，或更新一下 CocoaPods 版本。
+
+#### 去除 SDWebImage 的依赖（版本需 >= 3.0.4）
+
+Podfile 相应的配置变为：
+```
+pod 'YBImageBrowser/NOSD'
+pod 'YBImageBrowser/VideoNOSD'  //视频功能需添加
+```
+这时你必须定义一个类实现`YBIBWebImageMediator`协议，并赋值给`YBImageBrowser`类的`webImageMediator`属性（可以参考 `YBIBDefaultWebImageMediator`的实现）。
+
+
+## 手动导入
+
+1. 下载 YBImageBrowser 文件夹所有内容并且拖入你的工程中，视频功能还需下载 Video 文件夹所有内容。
+2. 链接以下 frameworks：
+* SDWebImage
+* YYImage
+3. 导入 `YBImageBrowser.h`，视频功能需导入`YBIBVideoData.h`
+4. 注意：如果你需要支持 WebP，可以在 Podfile 中添加 `pod 'YYImage/WebP'`，或者到手动下载 [YYImage 仓库](https://github.com/ibireme/YYImage) 的 webP 支持文件。
+
+
+
+
+# 用法
+
+初始化`YBImageBrowser`并且赋值数据源`id<YBIBDataProtocol>`，默认提供`YBIBImageData` (图片) 和`YBIBVideoData` (视频) 两种数据源。
+
+图片处理是组件的核心，笔者精力有限，视频播放做得很轻量，若有更高的要求最好是自定义 Cell，望体谅。
+
+Demo 中提供了很多示例代码，演示较复杂的拓展方式，所以若需要深度定制最好是下载 Demo 查看。
+
+建议不对`YBImageBrowser`进行复用，目前还存在一些逻辑漏洞。
+
+
+## 基本使用
+
+```
+// 本地图片
+YBIBImageData *data0 = [YBIBImageData new];
+data0.imageName = ...;
+data0.projectiveView = ...;
+
+// 网络图片
+YBIBImageData *data1 = [YBIBImageData new];
+data1.imageURL = ...;
+data1.projectiveView = ...;
+
+// 视频
+YBIBVideoData *data2 = [YBIBVideoData new];
+data2.videoURL = ...;
+data2.projectiveView = ...;
+
+YBImageBrowser *browser = [YBImageBrowser new];
+browser.dataSourceArray = @[data0, data1, data2];
+browser.currentPage = ...;
+[browser show];
+```
+
+
+## 设置支持的旋转方向
+
+当图片浏览器依托的 UIViewController 仅支持一个方向：
+
+这种情况通过`YBImageBrowser.new.supportedOrientations`设置图片浏览器支持的旋转方向。
+
+否则：
+
+上面的属性将失效，图片浏览器会跟随控制器的旋转而旋转，由于各种原因这种情况的旋转过渡有瑕疵，建议不使用这种方式。
+
+
+## 自定义图标
+
+修改`YBIBIconManager.sharedManager`实例的属性。
+
+
+## 自定义文案
+
+修改`YBIBCopywriter.sharedCopywriter`实例的属性。
+
+
+## 自定义 Toast / Loading
+
+实现`YBIBAuxiliaryViewHandler`协议，并且赋值给`YBImageBrowser.new.auxiliaryViewHandler`属性，可参考和协议同名的默认实现类。
+
+
+## 自定义工具视图（ToolView）
+
+默认实现的`YBImageBrowser.new.defaultToolViewHandler`处理器可以做一些属性配置，当满足不了业务需求时，最好是进行自定义，参考默认实现或 Demo 中“查看原图”功能实现。
+
+定义一个或多个类实现`YBIBToolViewHandler`协议，并且装入`YBImageBrowser.new.toolViewHandlers`数组属性。建议使用一个中介者来实现这个协议，然后所有的工具视图都由这个中介者来管理，当然也可以让每一个自定义的工具 UIView 都实现`YBIBToolViewHandler`协议，请根据具体需求取舍。
+
+
+## 自定义 Cell
+
+当默认提供的`YBIBImageData` (图片) 和`YBIBVideoData` (视频) 满足不了需求时，可自定义拓展 Cell，参考默认实现或 Demo 中的示例代码。
+
+定义一个实现`YBIBCellProtocol`协议的`UICollectionViewCell`类和一个实现`YBIBDataProtocol`协议的数据类，当要求不高时实现必选协议方法就能跑起来了，若对交互有要求就相对比较复杂，最好是参考默认的交互动效实现。
+
+在某些场景下，甚至可以直接继承项目中的 Cell 来做自定义。
+
+
+# 常见问题
+
+## SDWebImage Pods 版本兼容问题
+
+SDWebImage 有两种情况会出现兼容问题：该库对 SDWebImage 采用模糊向上依赖，但将来 SDWebImage 可能没做好向下兼容；当其它库依赖 SDWebImage 更低或更高 API 不兼容版本。对于这种情况，可以尝试以下方式解决：
+- Podfile 中采用去除 SDWebImage 依赖的方式导入，只需要实现一个中介者（见[安装](#安装)部分）。
+- 更改其它库对 SDWebImage 的依赖版本。
+- 手动导入 YBImageBrowser，然后修改`YBIBDefaultWebImageMediator`文件。
+
+为什么不去除依赖 SDWebImage 自己实现？时间成本太高。
+为什么不拖入 SDWebImage 修改类名？会扩大组件的体积，若外部有 SDWebImage 就存在一份多余代码。
+
+## 依赖的 YYImage 与项目依赖的 YYKit 冲突
+
+实际上 YYKit 有把各个组件拆分出来，建议项目中分开导入：
+```
+pod 'YYModel'
+pod 'YYCache'
+pod 'YYImage'
+pod 'YYWebImage'
+pod 'YYText'
+...
+```
+而且这样更灵活便于取舍。
+
+## 低内存设备 OOM 问题
+
+组件内部会降低在低内存设备上的性能，减小内存占用，但若高清图过多，可能需要手动去控制（以下是硬件消耗很低的状态）：
+
+```
+YBIBImageData *data = YBIBImageData.new;
+// 取消预解码
+data.shouldPreDecodeAsync = NO;
+// 直接设大触发裁剪比例，绘制更小的裁剪区域压力更小，不过可能会让用户感觉奇怪，放很大才开始裁剪显示高清局部（这个属性很多时候不需要显式设置，内部会动态计算）
+data.cuttingZoomScale = 10;
+
+YBImageBrowser *browser = YBImageBrowser.new;
+// 调低图片的缓存数量
+browser.ybib_imageCache.imageCacheCountLimit = 1;
+// 预加载数量设为 0
+browser.preloadCount = 0;
+```
+
+## 视频播放功能简陋
+
+关于大家提的关于视频的需求，有些成本过高，笔者精力有限望体谅。若组件默认的视频播放器满足不了需求，就自定义一个 Cell 吧，把成熟的播放器集成到组件中肯定更加的稳定。
+
+## 关于 Swift 版本
+
+考虑时间成本，目前没有写 Swift 版本的计划。
