swift - 如何在 Swift 项目中导入 Zbar Framework

Question

我有一个项目，目前正在尝试转换为 Swift 项目，但我不知道如何展示一个从相机源扫描的 Zbar 条形码阅读器。在我当前的项目中，我这样调用

- (IBAction)scanButton:(id)sender {

    // ADD: present a barcode reader that scans from the camera feed
    ZBarReaderViewController *reader = [ZBarReaderViewController new];
    reader.readerDelegate = self;
    reader.supportedOrientationsMask = ZBarOrientationMaskAll;

    ZBarImageScanner *scanner = reader.scanner;
    // TODO: (optional) additional reader configuration here

    // EXAMPLE: disable rarely used I2/5 to improve performance
    [scanner setSymbology: ZBAR_I25
                   config: ZBAR_CFG_ENABLE
                       to: 0];

    // present and release the controller
    [self presentViewController:reader animated:YES completion:nil];}

注意:到目前为止我做了什么

1. 将框架复制到swift中

2. 将框架路径添加到 header 搜索路径(目标部分 > build设置)

   • $(PROJECT_DIR)/Test/ZBarSDK/Headers/ZBarSDK
   • 为桥接创建了 Projectname-Bridging-Header.h(添加了来自 zbar 的所有 h 文件)
   • 将 Projectname-Bridging-Header.h 添加到 header 搜索路径

在那之后，如果我写“import ZBarSDK”或 ZBarReaderDelegate 仍然给我错误!

对于 swift 3:

extension ZBarSymbolSet: Sequence {
    public func makeIterator() -> NSFastEnumerationIterator {
        return NSFastEnumerationIterator(self)
    }
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        // ADD: get the decode results
        let results: NSFastEnumeration = info[ZBarReaderControllerResults] as! NSFastEnumeration

        var symbolFound : ZBarSymbol?

        for symbol in results as! ZBarSymbolSet {
            symbolFound = symbol as? ZBarSymbol
            break
        }
        let resultString = symbolFound!.data
        print(resultString)
    }
