二维码

1、

去下载SDK：

http://zbar.sourceforge.net/iphone/index.html

。
2、新建你的IOS Project。
3、导入ZbarSDK，直接拖动你下载的ZbarSDK到你的项目，并且选择copy选项。

4、添加如下framework

5、在appDelegate文件的以下方法中加入如下：

1. - (BOOL)application:(UIApplication *)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions
   
2. {
   
3.     //your code
   
4.     [ZBarReaderViewclass];
   
5.     return YES;
   
6. }

复制代码

6、在你需要使用扫描功能的ViewController.h文件添加如下：

1. #import
   
2. #import "ZBarSDK.h"
   
3. @interface ScanViewController : UIViewController
   
4. {
   
5.     ZBarReaderView*readerView;
   
6.     ZBarCameraSimulator*cameraSim;
   
7. }
   
8. @property (retain, nonatomic) IBOutlet ZBarReaderView*readerView;
   
9. @end

复制代码

7、在你需要使用扫描功能的ViewController.m文件添加如下：

1. #import "ScanViewController.h"
   
2. @interface ScanViewController ()
   
3. @end
   
4. @implementation ScanViewController
   
5. @synthesize readerView;
   
6. - (void)viewDidLoad
   
7. {
   
8.     [superviewDidLoad];   
   
9.     //your code   
   
10.     readerView.readerDelegate =self;
    
11.     [readerViewsetAllowsPinchZoom:YES];
    
12.     if (TARGET_IPHONE_SIMULATOR){
    
13.        cameraSim =[[ZBarCameraSimulator alloc]initWithViewController:self];
    
14.        cameraSim.readerView= readerView;
    
15.     }
    
16. }
    
17. -(void)viewDidAppear:(BOOL)animated
    
18. {
    
19.     [readerView start];
    
20. }
    
21. -(void)viewDidDisappear:(BOOL)animated
    
22. {
    
23.     [readerView stop];
    
24. }
    
25. 
    
26. -(void) readerView:(ZBarReaderView *)readerViewdidReadSymbols:(ZBarSymbolSet *)symbols fromImage:(UIImage*)image
    
27. {
    
28.     NSString *codeData =[[NSString alloc] init];;
    
29.     for (ZBarSymbol *sym insymbols) {
    
30.        codeData =sym.data;
    
31.        break;
    
32.     }
    
33.     UIAlertView *alert =[[UIAlertView alloc] initWithTitle:@"掃描結果" message:codeDatadelegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil,nil];
    
34.     [alert show];
    
35. }
    
36. 
    
37. -(void) imagePickerController:(UIImagePickerController *)pickerdidFinishPickingMediaWithInfo:(NSDictionary *)info
    
38. {
    
39.     // 得到条形码结果
    
40.     id results =
    
41.     [info objectForKey:ZBarReaderControllerResults];
    
42.     ZBarSymbol *symbol =nil;
    
43.     for(symbol inresults)
    
44.        break;
    
45.     //获得到条形码
    
46.     //NSString*dataNum=symbol.data;
    
47.     //扫描界面退出
    
48.     [pickerdismissModalViewControllerAnimated: YES];
    
49. }
