向Tesseract ios SDK添加新语言

Question

I am able to compile the English version which is already in sample for tesseract but not able to add other language like swe.traineddata .

I'm doing like this

G8RecognitionOperation *operation = [[G8RecognitionOperation alloc] initWithLanguage:@"eng+swe"];

When adding this its giving this error but working fine with English.

Cube ERROR (CubeRecoContext::Load): unable to read cube language model params from /private/var/mobile/Containers/Bundle/Application/D93B654A-1E46-4A34-9A83-95C6FC903085/*.app/tessdata/swe.cube.lm
Cube ERROR (CubeRecoContext::Create): unable to init CubeRecoContext object
init_cube_objects(true, &tessdata_manager):Error:Assert failed:in file tessedit.cpp, line 203

Answer 1

The fact it does not work has to do with the engine mode. If you use the CubeOnly or TesseractCubeCombined, you need 'cube' files. Engine mode TesseractOnly works fine.

Answer 2

you are missing some of files,I think so.Also check on Create Folder References.that helped me once.
