[iOS Live Text ] 使用iOS16的LiveText 用swiftUI写一个离线产品包装扫描工具

把之前写的小工具记录一下。

❤️ ,工具使用SwiftUI为主，由于LiveText还没有提供SwiftUI的API，所以使用switfui包装了一下Uikit的内容。

注意：仅支持iOS16系统以及A12芯片以上设备。

分享一下主要实现代码：

包装的live-text swiftUI组件:文本识别取景器,传入需要绑定的变量，识别文本后，将值传回swiftui页面。

struct LiveScaner: UIViewControllerRepresentable {
  
    @Binding var startScanning: Bool
  
  
    @Binding var scanText: String

    func makeUIViewController(context: Context) -> DataScannerViewController {
        let controller = DataScannerViewController(
                            recognizedDataTypes: [.text()],
                            qualityLevel: .accurate,
                            recognizesMultipleItems: false, isHighFrameRateTrackingEnabled: true, isPinchToZoomEnabled: true, isHighlightingEnabled: true
                        )
  
        controller.delegate = context.coordinator
  
        return controller
    }
  
    func updateUIViewController(_ uiViewController: DataScannerViewController, context: Context) {
  
        if startScanning {
            try? uiViewController.startScanning()
        } else {
            uiViewController.stopScanning()
        }
    }
  
    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }
  
    class Coordinator: NSObject, DataScannerViewControllerDelegate {
  
        func findhks(waitSearch:String)->Array<CategoriesItem>{
   
  
            print("list:")
            print(waitSearch.replacing(/[、\s，。：（）]/, with: ""))
            let findRes:Array<CategoriesItem> =  CateList.filter{ fl in
                print( fl.name,waitSearch.score(word: fl.name))
                return waitSearch.score(word: fl.name.replacing(/[、\s，。：（）]/, with: "")) > 0
            }
    
            return findRes
   
        }
  
        var parent: LiveScaner
  
        init(_ parent: LiveScaner) {
            self.parent = parent
        }
  
        func dataScanner(_ dataScanner: DataScannerViewController, didTapOn item: RecognizedItem) {
            switch item {
            case .text(let text):
        
                parent.searchList = findhks(waitSearch: text.transcript)
                parent.scanText = text.transcript
            default: break
            }
        }
  
   
  
  
    }
}

swiftUI使用

LiveScaner(startScanning: $startScanning, scanText: $scanText,searchList:$searchList)
                       .frame(height: 120)
