Bei der Integration von Tesseract SDK in meine iOS-App treten einige Fehler auf. Das Verfahren, das ich befolgt habe -

1) "libtesseract_full.a" in xcode gezogen 2) "tessdata" -Ordner in xcode gezogen 3) "baseapi.h" in xcode gezogen

Jetzt, wenn ich Tesseract benutze -

// init the tesseract engine.
tess = new TessBaseAPI();

tess->SimpleInit([dataPath cStringUsingEncoding:NSUTF8StringEncoding],  // Path to tessdata-no ending /.
                 "eng",  // ISO 639-3 string or NULL.
                 false);

Ich erhalte folgende Fehlermeldungen: (Ich denke, es fehlt ein Framework oder ähnliches, aber ich erhalte nicht, was fehlt. Das tesseract-Demo-Projekt funktioniert auf meinem System einwandfrei.)
