运行 iOS 的 Nativescript OCR 插件时出现问题

Question

首先，对不起我的英语。我正在运行宁我的 Nativescript Angular 应用程序使用 nativescript OCR 1.0.0 插件。该识别适用于 Android OS 但不适用于 iOS。当我运行 Visual Studio Code for MacOS 中的项目时，我看到了一些问题，例如：

/Users/macintosh/....../platforms/ios/Pods/TesseractOCRiOS/TesseractOCR/G8TesseractParameters.h:2353:5: warning: '@param' command used in a comment that is not attached to a function declaration [-Wdocumentation]

Please call SetImage before attempting recognition

Recognize failed, check the log for possible details.

如何使用 iOS 的 OCR 插件并正确识别图像？

Answer 1

原始代码部分无效

doRecognize(args): void {
    let img: ImageSource = new ImageSource();
    img.fromAsset(args.imagenEnAsset);

    args.ocr.retrieveText({
        image: img,
        whitelist: "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789<",     
        blacklist: "/Ñ,",
        onProgress: (percentage: number) => {
            console.log(`Decoding progress: ${percentage}%`);
        }
    })

现在工作代码部分

doRecognize(args): void {
    let img: ImageSource = new ImageSource();
    img.fromAsset(args.imagenEnAsset)
        .then(
            (imageSource) => {
                if (imageSource) {
                    args.ocr.retrieveText({
                        image: imageSource,
                        whitelist: "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789<",     
                        blacklist: "/Ñ,", 
                        onProgress: (percentage: number) => {
                            console.log(`Decoding progress: ${percentage}%`);
                        }
                    })
