use Zbar SDK sample
1、参考前面Zbar SDK的 iOS使用ZbarSDK实现扫描二维码以及条形码功能 的帖子将那下载的SDK拖入到项目中。
2、加入Library如下！
3、到Build Settings刪除那 armv7s，留下armv7，如下！
4、新建你的viewController，.h文件如下？未使用xib？！
1. #import <UIKit/UIKit.h>
2. #import "ZBarSDK.h"
3.
4. @interface QRCodeViewController :
UIViewController<ZBarReaderViewDelegate> {
5.
6. ZBarReaderView *readerView;
7. ZBarCameraSimulator *cameraSim;
8.
9. }
10.
11. @end
12.
复制代码
5、.m文件如下！
普通浏览复制代码保存代码打印代码
1. #import "QRCodeViewController.h" 2.
3. @interface QRCodeViewController () 4.
5. @end
6.
7. @implementation QRCodeViewController 8.
9.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)ni
bBundleOrNil
10. {
11. self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNi
l];
12. if (self) {
13. [self setTitle:@"QRCode"]; 14. [self.tabBarItem setTitle:@"QRCode"]; 15. }
16. return self;
17. }
18.
19. - (void)viewDidLoad
20. {
21. [super viewDidLoad];
22.
23. readerView = [[ZBarReaderView alloc] init];
24. readerView.readerDelegate = self; 25. [readerView setShowsFPS:YES]; 26. [readerView setAllowsPinchZoom:YES]; 27. [readerView setFrame:CGRectMake(0, 0, 320, [UIScreen mainScreen
].bounds.size.height - 20)];
28.
29. [self.view addSubview:readerView]; 30.
31. //你可以自定義這個掃瞄界面在這裡隨意定義。
32.
33.
34. if(TARGET_IPHONE_SIMULATOR) { 35. cameraSim = [[ZBarCameraSimulator alloc] 36. initWithViewController: self]; 37. cameraSim.readerView = readerView; 38. }
39. }
40.
41. - (void)viewWillAppear:(BOOL)animated 42. {
43. [super viewWillAppear:animated]; 44. }
45.
46. - (void)viewDidAppear:(BOOL)animated 47. {
48. [readerView start];
49. }
50.
51. - (void)didReceiveMemoryWarning
52. {
53. [super didReceiveMemoryWarning]; 54. // Dispose of any resources that can be recreated.
55. }
56.
57. - (void)viewDidDisappear:(BOOL)animated 58. {
59. [super viewDidDisappear:YES]; 60. [readerView stop];
61. }
62.
63.
- (void)readerView:(ZBarReaderView *)readerView didReadSymbols:(ZBar
SymbolSet *)symbols fromImage:(UIImage *)image 64. {
65. for (ZBarSymbol *sym in symbols) { 66. UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"
掃瞄結果
" message:[sym data] delegate:self cancelButtonTitle:@"OK" otherButt
onTitles:nil, nil];
67. [alert show];
68. break;
69. }
70. }
71.
72.
-(void) imagePickerController:(UIImagePickerController *)picker didF
inishPickingMediaWithInfo:(NSDictionary *)info 73. {
74. // 得到条形码结果
75. // id<NSFastEnumeration> results = 76. // [info objectForKey: ZBarReaderControllerResults];
77. // ZBarSymbol *symbol = nil;
78. // for(symbol in results)
79. // break;
80. //获得到条形码
81. //NSString *dataNum=symbol.data; 82. //扫描界面退出
83. [picker dismissModalViewControllerAnimated: YES]; 84. }
85.
86. @end
87.
6、那demo截圖如下！
