我想您问的是从图像中识别文本 (OCR)，而不是像将图像文件编码为 base64 之类的问题
iPhone 中没有内置 OCR 库。
根据您的预算和想要达到的准确度，您可以尝试
I suppose you are asking about recognizing text from images (OCR) and not about something like encoding image file into base64
There's no build-in OCR libraries in iPhone.
Depending on your budget and what accuracy you trying to achieve, you can try
我用过超立方体。其准确度范围为 0-100%，具体取决于图像捕获的程度、文本的字体和颜色等各种因素。
但如果您有非常清晰的图像和非常清晰的文本，它可以给您很好的结果。
I have used tesseract. Its accuracy ranges from 0-100% depending upon various factors like how well the image is captured,fonts and color of the text etc.
But it can give you very good result if you have a very clear image with very clear text.
