Please use labels and text to provide additional information.
example code in objective see, this function is looped for multiple images 
however the app is crash because of memory problem

   -(void)recognizeImageWithTesseract:(UIImage *)img
    {

     UIImage *testb = [img blackAndWhite];

       Tesseract* tesseract = [[Tesseract alloc] initWithLanguage:@"eng+ita"];

       tesseract.delegate = self;
         [tesseract setVariableValue:@"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz+-/*._=':!)(" forKey:@"tessedit_char_whitelist"]; //limit search
        [tesseract setImage:testb];
        [tesseract recognize];
         recognizedText = [tesseract recognizedText];
        tesseract = nil; //deallocate and free all memory
}
