示例

要运行示例项目，请克隆仓库，然后首先从 Example 目录运行 pod install。

NLRecordParam *param = [NLRecordParam recordConfigWithVideoRatio:NLShootRatioFullScreen shootMode:photoVideoMode position:AVCaptureDevicePositionBack maxRecordTime:15.0f minRecordTime:1.0f isCompression:NO waterMark:nil isFilter:YES isShowBeautyBtn:NO isShowAlbumBtn:YES currentVC:self];
[NLRecordManager shareManager].recordParam = param;
NLPhotoViewController *page = [NLPhotoViewController new];
[self presentViewController:page animated:YES completion:nil];
