小编Son*_*ran的帖子

我是Ios的新手.我正在学习迅速和被忽视的对象c.

目前,我正在编写一个带有swift和xcode 6.1的演示,它可以扫描来自摄像头的qrcode和条形码或来自图像库的图像.

我知道AVFoundation框架支持扫描qrcode和条形码,但它只能从相机扫描.

我搜索并找到zbarSDK,它支持来自摄像头和图像的扫描码.我在http://zbar.sourceforge.net/iphone/sdkdoc/和Swift中的NSFastEnumeration中执行指令(将代码转换为swift).但是,当我运行app时,从库中选择图像后,就会发生错误.

这是我的代码

import UIKit
    import AVFoundation

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

    class FirstViewController: UIViewController, ZBarReaderDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

        let reader = ZBarReaderController()

        @IBOutlet weak var lblResult: UILabel!
        @IBOutlet weak var imgView: UIImageView!

        override func viewDidLoad() {
            super.viewDidLoad()
            reader.delegate = self
        }

        override func didReceiveMemoryWarning() {
            super.didReceiveMemoryWarning()
            // Dispose of any resources that can be recreated.
        }

        @IBAction func scanCode(sender: AnyObject) {
            let scanner …

之前,我尝试使用zbar SDK来做到这一点,但它发生错误,我不知道如何修复它,我在帖子中发布此错误:扫描qrcode和条形码从相机和图像从swift图像库中选取,但没有人回答.

我正在尝试使用ZXingObjC扫描来自图像和相机的qrcode和条形码https://github.com/TheLevelUp/ZXingObjC,我读了它的用法并尝试转换为swift.但它发生了错误,我不知道如何解决它.

这是我的代码:

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet weak var lblResult: UILabel!
    @IBOutlet weak var imgView: UIImageView!
    var imagePicker = UIImagePickerController()

    override func viewDidLoad() {
        super.viewDidLoad()
        imagePicker.delegate = self
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func scanCode(sender: AnyObject) {
        imagePicker.sourceType = .PhotoLibrary
        imagePicker.allowsEditing = false
        presentViewController(imagePicker, animated: true, completion: nil)
    }

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingMediaWithInfo info: NSDictionary!) …
