?添加依賴庫：AVFoundation.framework验懊、libiconv.2.dylib、CoreMedia.framework、CoreVideo.framework，其中l(wèi)ibzbar.a是SDK中的,(如果需要通過SVN上傳自己代碼時丐箩，要記得還有這個.a文件)
在你要進(jìn)行添加掃描的界面的.h里可直接復(fù)制到工程里
添加頭文件
import "ZBarSDK.h"
//設(shè)置代理
@protocol ErweimaDelegate
//掃描出結(jié)果則調(diào)用這個方法
-(void)finishRead:(NSString *)barCode;
@end
@interface ErweimaViewController : superVC < ZBarReaderViewDelegate > //此處superVC是自定義的父類
@property (strong, nonatomic)id < ErweimaDelegate >delegate;
@end
4.在.m文件中:
@interface ErweimaViewController ()
{
ZBarReaderViewrederView;//二維碼掃描View，可自定義樣式
UIImageViewlineView;//自定義的掃描線
NSTimer *time;//定時器恤煞，控制掃描線跑動
}
//在進(jìn)入界面時就開始掃描
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];[rederView start];
}
//退出界面時就停止掃描
(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[rederView stop];
}
-(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.title = @"掃描";
