二维码生成与扫描

一、下载 libqrencode SDK

1.以从github上下载好ZBarSDK，导入项目，并且导入相关iOS.framework 如图：

2.在ViewController.m中导入头文件

#import "QRCodeGenerator.h"

#import "ZBarSDK.h"

3.导入协议ZBarReaderDelegate

- (IBAction)sss:(id)sender {

//初始化相机控制器

reader = [ZBarReaderViewController new];

//设置代理

reader.readerDelegate = self;

//基本适配

reader.supportedOrientationsMask = ZBarOrientationMaskAll;

//二维码/条形码识别设置

ZBarImageScanner *scanner = reader.scanner;

[scanner setSymbology: ZBAR_I25

config: ZBAR_CFG_ENABLE

to: 0];

//弹出系统照相机，全屏拍摄

[self presentModalViewController: reader

animated: YES];

}

4、在Info.plist中导入

使用相机NSCameraUsageDescription
