1.首先使用Cocoapods导入库 ZBarSDK

2.敲代码:

@interface ViewController : UIViewController<ZBarReaderDelegate>


@end

#import "ViewController.h"
#define ScreenFrame [[UIScreen mainScreen]bounds]
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    UIButton * btn = [UIButton buttonWithType:UIButtonTypeCustom];
    btn.frame = CGRectMake(0, 0, 50, 50);
    [btn setTitle:@"扫描" forState:UIControlStateNormal];
    btn.backgroundColor = [UIColor redColor];
    [btn addTarget:self action:@selector(erweima:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];
    // Do any additional setup after loading the view, typically from a nib.
}
-(void)erweima:(UIButton *)btn{
    ZBarReaderViewController * reader = [ZBarReaderViewController new];//初始化相机控制器
    reader.readerDelegate = self;
    reader.supportedOrientationsMask = ZBarOrientationMaskAll;//基本适配
    reader.showsHelpOnFail = YES;
    reader.scanCrop = CGRectMake(0, 0, 1, 1);
    ZBarImageScanner * scanner = reader.scanner;
    [scanner setSymbology:25 config:0 to:0];
    UIView * view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, ScreenFrame.size.width, ScreenFrame.size.height)];
    reader.cameraOverlayView = view;
    [self presentViewController:reader animated:YES completion:^{
        
    }];
    
}
- (void) imagePickerController: (UIImagePickerController*) reader
 didFinishPickingMediaWithInfo: (NSDictionary*) info{
    id<NSFastEnumeration> results =
    [info objectForKey: ZBarReaderControllerResults];
    ZBarSymbol *symbol = nil;
    for(symbol in results)
        break;
    UIAlertView * alert = [[UIAlertView alloc]initWithTitle:@"消息" message:symbol.data delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:@"OK1", nil];
        [alert show];

}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end
