Swift Platform Carthage Compatible

QRCodeScan

主要内容的介绍

  • 二维码、条形码的生成
  • 二维码、条形码的扫描
  • 自定义扫描页面

Requirements

  • Object-tive C、 Swift 4.2
  • iOS 9.0+
  • Xcode 9.x

Installation

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

To integrate QRCodeScan into your Xcode project using Carthage, specify it in your

Cartfile
:
github "youmyc/QRCodeScan"

Run

carthage update --platform iOS
to build the framework and drag the built
ScanQRCode.framework
into your Xcode project.

Manually

Just download the project, and drag and drop the "QRCode/Common" folder in your project.

Usage

1、在 info.plist 中添加以下字段(iOS 10 之后需添加的字段)

NSCameraUsageDescription
二维码扫描,需要您的相机
NSPhotoLibraryAddUsageDescription
App需要您的同意,才能保存图片到您的相册

2、扫描页面调用

  • 可自定义扫描页面,详情查看demo
QRCodeViewController * qrcVC = [[UIStoryboard storyboardWithName:@"QRCode" bundle:nil] instantiateViewControllerWithIdentifier:@"qrc"];
qrcVC.title = @"条形码";
// YES 为条形码,NO 为二维码
qrcVC.isBarCode = YES;
// 边框颜色
qrcVC.angleColor = [UIColor colorWithRed:0.122 green:0.565 blue:0.902 alpha:1.000];
[self.navigationController pushViewController:qrcVC animated:YES];

3、根据环境光传感器变化开启与关闭闪光灯

  • 需环境光传感器变化回调,实用ScanViewDelegate即可
/**
 环境光传感器变化

@param scanView ScanView @param flashLamp 是否开启闪光灯 */

  • (void)lightSensorDidChange:(ScanView *)scanView show:(BOOL)flashLamp;
  • 闪光灯的开启与关闭,用ScanView的实例变量调用以下方法即可
/**
开启闪光灯
*/
  • (void)open;
  • /** 关闭闪光灯 */

    • (void)close;

    3、二维码/条形码的生成

    • 调用以下方法生成二维码、条形码
    /**
     生成二维码
    
    

    @param content 内容 @param size 大小 @return 二维码 */

    • (UIImage *)generateQRCodeWithContent:(NSString *)content size:(CGSize)size;

    /** 生成条形码

    @param content 内容 @return 条形码 */

    • (UIImage *)generateBarCodeWithContent:(NSString *)content size:(CGSize)size;

    • 二维码保存(截取后会自动保存到相册)
    /**
    截图
    
    

    @param view 所需截图的View @return 截图后的图片 */

  • (UIImage *)screenShotWithView:(UIView *)view;

  • 4、二维码的识别

    /**
    打开相册
    
    

    @param controller 当前控制器 */

    • (void)openAlbum:(UIViewController *)controller;
    @class QRCdiscern;
    
    

    @protocol QRCdiscernDelegate

    @optional

    /** 识别完成后回调

    @param discern QRCdiscern @param result 识别结果 */

    • (void)discernDidFinish:(QRCdiscern *)discern result:(NSString *)result;

    @end

    效果
