iOS

Zbar64位

正文：

首先下载一个支持64位系统的ZbarSDK的包，保存在了我的云盘里，地址：ZbarSDK

  1. 把文件拖到工程里面
  2. 然后添加依赖库：AVFoundation.framework、libiconv.2.dylib、CoreMedia.framework、CoreVideo.framework，其中libzbar.a是SDK中的,(如果需要通过SVN上传自己代码时，要记得还有这个.a文件)

  3. 在你要进行添加扫描的界面的.h里 可直接复制到工程里

    添加头文件

     
  1.  #import "ZBarSDK.h"            
    2.       
  2.  //设置代理            
    3.       
  3.  @protocol ErweimaDelegate <NSObject>            
    4.       
  4.  //扫描出结果则调用这个方法            
    5.       
  5.  -(void)finishRead:(NSString *)barCode;            
    6.       
  6.  @end            
    7.       
  7.   
    8.       
  8.  @interface ErweimaViewController : superVC < ZBarReaderViewDelegate > //此处superVC是自定义的父类            
    9.       
  9.  @property (strong, nonatomic)id < ErweimaDelegate >delegate;            
    10.       
  10.  @end            
    11.

4.在.m文件中:

     
  1.  @interface ErweimaViewController ()            
    2.       
  2.  {            
    3.       
  3.  ZBarReaderView *rederView;//二维码扫描View，可自定义样式            
    4.       
  4.  UIImageView *lineView;//自定义的扫描线            
    5.       
  5.  NSTimer *time;//定时器，控制扫描线跑动            
    6.       
  6.  }            
    7.      
    
     
  1.  //在进入界面时就开始扫描            
    2.       
  2.  -(void)viewWillAppear:(BOOL)animated{

    5.       
  5.  [rederView start];            
    6.       
  6.  }            
    7.       
  7.  //退出界面时就停止扫描            
    8.       
  8.  - (void)viewWillDisappear:(BOOL)animated
