swift - 如何使用CIFilter生成dataMatrix？

Question

我收到错误:

Value for key inputBarcodeDescriptor of type CIDataMatrixCodeDescriptor is not yet supported

let string = "tempValue&123"
let data = string.data(using: String.Encoding.ascii, allowLossyConversion: false)
guard let data = data else {
    return nil
}

let descriptor = CIDataMatrixCodeDescriptor(payload: data, rowCount: 1, columnCount: 1, eccVersion: CIDataMatrixCodeDescriptor.ECCVersion(rawValue: 0))        
let inputParameter  = ["inputBarcodeDescriptor": descriptor]        
let datafilter = CIFilter(name: "CIBarcodeGenerator", parameters: inputParameter)        
let image = datafilter?.outputImage        
print(image)

好吧，我认为你应该相信这个运行时警告。您无法使用 CIDataMatrixCodeDescriptor 创建条形码；该类已记录，但实际上并没有起作用。请改用不同的 CIBarcodeDescriptor 子类(例如 CIAztecCodeDescriptor)。
