在我的 iOS 应用程序中集成 Tesseract SDK 时出现一些错误。我遵循的程序 -
1) 在 xcode 中拖动“libtesseract_full.a” 2) 在 xcode 中拖动“tessdata”文件夹 3) 在 xcode 中拖动“baseapi.h”
现在当我使用 Tesseract -
// 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);
我收到以下错误(我认为缺少一些框架或类似的东西,但没有得到缺少的东西,tesseract 演示项目在我的系统上运行良好)
