版本

Vesrion 1.0

This version requires Xcode 9.0 and Swift 4.

使用帮助

首先, import GTMBarcodeScanner.

import GTMBarcodeScanner

创建Scanner

let scanner = BarcodeScanner.create(view: self.view)

// 风格设置
scanner.makeStyle { (make) in
    let color = UIColor.init(red: 255/255, green: 157/255, blue: 0/255, alpha: 1)
    make.positionUpVal(44)
    make.anglePosition(ScanViewStyle.AnglePosition.inner)
    make.angleLineWeight(5)
    make.angleLineLength(18)
    make.isShowRetangleBorder(true)
    make.width(280)
    make.height(180)
    make.retangleLineWeight(1/UIScreen.main.scale)
    make.animateType(ScanViewStyle.Animation.lineMove)
    make.colorOfAngleLine(color)
    make.colorOfRetangleLine(color)
    let c = UIColor(red: 255/255, green: 157/255, blue: 0/255, alpha: 0.5)
    make.colorOutside(c)
    make.soundSource(forName: "VoiceSearchOn", andType: "wav")
}

// 配置
scanner.config { (make) in
    make.autoCloser(true)       // 自动拉近镜头
    make.caputureImage(true)    // 记录扫码的源图片
    make.printLog(true)         // 调试信息打印控制
}

// 设置代理
scanner.delegate = self

// 开始扫码
scanner.start()

代理对象

public protocol GTMBarcodeCoreDelegate: class {
    func barcodeRecognized(result: BarcodeResult)
    func lightnessChange(needFlashButton: Bool)
    func barcodeForPhoto(result: BarcodeResult?)
}

风格设置

public struct ScanViewStyle {

    /// 是否需要绘制扫码矩形框,默认YES
    public var isShowRetangle:Bool = true
    public var size = CGSize(width: 255, height: 255)
    public var positionUpVal: CGFloat = 44
    ///矩形框线条颜色,默认白色
    public var colorRetangleLine = UIColor.white
    ///4个角的颜色
    public var colorAngleLine = UIColor(red: 0.0, green: 167.0/255.0, blue: 231.0/255.0, alpha: 1.0)
    ///非识别区域颜色,默认 RGBA (0,0,0,0.5),范围(0--1)
    public var colorOutside = UIColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 0.5)

    ///扫码区域的4个角类型
    public var anglePosition = AnglePosition.outer


    ///扫码区域4个角的宽度和高度
    public var angleW:CGFloat = 24.0
    public var angleH:CGFloat = 24.0
    ///扫码区域4个角的线条宽度,默认6,建议8到4之间
    public var angleLineWeight: CGFloat = 6
    public var retangleLineWeight: CGFloat = 1

    ///扫码动画效果: 线条或网格
    public var animateType = Animation.lineMove

    /// 动画效果的图像,如线条或网格的图像
    public var animateImage:UIImage?
    /// 动画 duration 值, 默认值 2.6
    public var animateDuration: TimeInterval = 2.6

    /// 扫描提示音资源文件
    public var soundSource: (name: String, type: String)?


    public init() { }
    
    public enum Animation {
        case lineMove
        case gridGrow
        case none
    }
    
    public enum AnglePosition {
        case inner
        case outer
        case on
    }
}
