Zbar (ZbarSymbolSet)和Xcode8的问题

Question

当我在Swift 2.2中使用Xcode8打开项目时，我对ZBar库的使用遇到了困难。我一直使用桥来运行这个库，但在Xcode上，我立即使用了ZbarSymbolSet的一个红色扩展。Use of undeclared type 'ZbarSymbolSet'

//Extension for Zbar
extension ZBarSymbolSet: SequenceType {
    public func generate() -> NSFastGenerator {
        return NSFastGenerator(self)
    }
}

Answer 1

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)
    }
