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)

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

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 <NSObject>

@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
