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)
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
import "ZBarSDK.h"
//设置代理
@protocol ErweimaDelegate
//扫描出结果则调用这个方法
-(void)finishRead:(NSString *)barCode;
@end
@interface ErweimaViewController : superVC < ZBarReaderViewDelegate > //此处superVC是自定义的父类
@property (strong, nonatomic)id < ErweimaDelegate >delegate;
@end
4.在.m文件中:
@interface ErweimaViewController ()
{
ZBarReaderViewrederView;//二维码扫描View，可自定义样式
UIImageViewlineView;//自定义的扫描线
NSTimer *time;//定时器，控制扫描线跑动
}
//在进入界面时就开始扫描
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];[rederView start];
}
//退出界面时就停止扫描
(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[rederView stop];
}
-(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.title = @"扫描";
[self initView];
}
