使用TZImagePickerController报错[NSUR

场景：项目中对react-native-syan-image-picker组件进行了修改，可以选择视频并且编辑
但选择图片时闪退，并报[NSURL initFileURLWithPath:]: nil string parameter错误

原因：因为选择的视频需要从iCloud上获取，在TZImageManager.m文件的

- (void)getVideoWithAsset:(PHAsset *)asset progressHandler:(void (^)(double progress, NSError *error, BOOL *stop, NSDictionary *info))progressHandler completion:(void (^)(AVPlayerItem *, NSDictionary *))completion;

方法里返回的info中拿不到视频地址，导致传给编辑视频界面的filePath是个nil，所以闪退

解决：
使用 requestExportSessionForVideo或者requestAVAssetForVideo代替requestPlayerItemForVideo方法即可

/// 从iCloud获取视频
