Installation 安装 #### CocoaPods > pod 'TZImagePickerController' # Full version with all features > pod 'TZImagePickerController/Basic' # No location code #### Carthage > github "banchichen/TZImagePickerController" #### 手动安装 > 将TZImagePickerController文件夹拽入项目中，导入头文件：#import "TZImagePickerController.h" ## 二. Example 例子 TZImagePickerController *imagePickerVc = [[TZImagePickerController alloc] initWithMaxImagesCount:9 delegate:self]; // You can get the photos by block, the same as by delegate. // 你可以通过block或者代理，来得到用户选择的照片. [imagePickerVc setDidFinishPickingPhotosHandle:^(NSArray *photos, NSArray *assets, BOOL isSelectOriginalPhoto) { }]; [self presentViewController:imagePickerVc animated:YES completion:nil]; ## 三. Requirements 要求 iOS 10 or later. 支持iOS10及以上系统。 TZImagePickerController uses Camera、Location、Microphone、Photo Library，you need add these properties to info.plist like Demo： TZImagePickerController使用了相机、定位、麦克风、相册，请参考Demo添加下列属性到info.plist文件： `Privacy - Camera Usage Description` `Privacy - Location Usage Description` `Privacy - Location When In Use Usage Description` `Privacy - Microphone Usage Description` `Privacy - Photo Library Usage Description` `Prevent limited photos access alert` ## 四. More 更多 If you find a bug, please create a issue. More information please view code. 如果你发现了bug，请提一个issue。 更多信息详见代码，也可查看我的博客: [我的博客](http://www.jianshu.com/p/1975411a31bb "半尺尘 - 简书") 关于issue: 请尽可能详细地描述**系统版本**、**手机型号**、**库的版本**、**崩溃日志**和**复现步骤**，**请先更新到最新版再测试一下**，如果新版还存在再提~如果已有开启的类似issue，请直接在该issue下评论说出你的问题 ## 五. FAQ 常见问题 **Q：pod search TZImagePickerController 搜索出来的不是最新版本** A：需要在终端执行cd转换文件路径命令退回到Desktop，然后执行pod setup命令更新本地spec缓存（可能需要几分钟）,然后再搜索就可以了 **Q：拍照后照片保存失败** A：请参考issue481：https://github.com/banchichen/TZImagePickerController/issues/481 的信息排查，若还有问题请直接在issue内评论 **Q：photos数组图片不是原图，如何获取原图？** A：请参考issue457的解释：https://github.com/banchichen/TZImagePickerController/issues/457 **Q：系统语言是中文/英文，界面上却有部分相册名字、返回按钮显示成了英文/中文？** A：请参考 https://github.com/banchichen/TZImagePickerController/issues/443 和 https://github.com/banchichen/TZImagePickerController/issues/929 **Q：预览界面能否支持传入NSURL、UIImage对象？** A：3.0.1版本已支持，需新接一个库：[TZImagePreviewController](https://github.com/banchichen/TZImagePreviewController)，请参考里面的Demo使用。 **Q：设置可选视频的最大/最小时长？照片的最小/最大尺寸？不符合要求的不显示** A：可以的，参照Demo的isAssetCanBeDisplayed方法实现。我会返回asset出来，显示与否你来决定，注意这个是一个同步方法，对于需要根据asset去异步获取的信息如视频的大小、视频是否存在iCloud里来过滤的，无法做到。如果真要这样做，相册打开速度会变慢，你需要改我源码。 如果需要显示，选择时才提醒用户不可选，则实现isAssetCanBeSelected，用户选择时会调用它 **Q：预览页面出现了导航栏？** A：https://github.com/banchichen/TZImagePickerController/issues/652 **Q：可否增加微信编辑图片的功能？** A：考虑下，优先级低 **Q：是否有QQ/微信群/钉钉群？** A：有「钉钉群：33192786」和「QQ群：859033147」，推荐加钉钉群，答疑响应更快 **Q：想提交一个Pull Request？** A：请先加钉钉群(33192786)说下方案，和我确认下，避免同时改动同一处内容。**一个PR请只修复1个问题，变动内容越少越好**。 **Q：demo在真机上跑不起来？** A：1、team选你自己的；2、bundleId也改成你自己的或改成一个不会和别人重复的。可参考[简书的这篇博客](https://www.jianshu.com/p/cbe59138fca6) **Q：3.6.4以上版本设置导航栏颜色无效？** A：参考Demo里的代码，加上imagePickerVc.navigationBar.standardAppearance的相关设置 **Q：设置导航栏颜色无效？导航栏颜色总是白色？** A：是否有集成WRNavigationBar？如有，参考其readme调一下它的wr_setBlackList，把TZImagePickerController相关的控制器放到黑名单里，使得不受WRNavigationBar的影响。如果没有集成，可在issues列表里搜一下看看类似的issue参考下，如实在没头绪，可加群提供个能复现该问题的demo，0~2天给你解决。最近发现WRNavigationBar的黑名单会有不生效的情况，临时解决方案大家可参考：[https://github.com/wangrui460/WRNavigationBar/issues/145](https://github.com/wangrui460/WRNavigationBar/issues/145) **Q：导航栏没了？** A：是否有集成GKNavigationBarViewController？需要升级到2.0.4及以上版本，详见issue：[https://github.com/QuintGao/GKNavigationBarViewController/issues/7](https://github.com/QuintGao/GKNavigationBarViewController/issues/7)。 **Q：有的视频导出失败？** A：升级到2.2.6及以上版本试试，发现是修正视频转向导致的，2.2.6开始默认不再主动修正。如需打开，可设置needFixComposition为YES，但有几率导致安卓拍的视频导出失败。此外也可参考这个issue：https://github.com/banchichen/TZImagePickerController/issues/1073 **Q：视频导出慢？** A：视频导出分两步，第一步是通过PHAsset获取AVURLAsset，如是iCloud视频则涉及到网络请求，耗时容易不可控，第二步是通过AVURLAsset把视频保存到沙盒，耗时不算多。但第一步耗时不可控，你可以拷贝我源码出来拿到第一步的进度给用户一个进度提示... **Q：有的图片info里没有PHImageFileURLKey？** A：不要去拿PHImageFileURLKey，没用的，只有通过Photos框架才能访问相册照片，光拿一个路径没用。 如果需要通过路径上传照片，请先把UIImage保存到沙盒，**用沙盒路径**。 如果你上传照片需要一个名字参数，请参考Demo**直接用照片名字**。 ## 六.
