ZBarSDK，一个比较优秀的开源项目，使用起来也很简单。

ZBarSDK是一个开源的SDK，可从这里下载到源码，该SDK实现了识别和读取各种条形码，包括EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 和 QR Code。

Step1.使用ZBarSDK 需要导入的framework

1.AVFoundation.framework

2.CoreMedia.framework

3.CoreVideo.framework

4.QuartzCore.framework

5.libiconv.dylib

Step2.在ViewController.h 导入#import "ZBarSDK.h"

Step3.在ViewController.h 继承 <ZBarReaderDelegate>协议

Step4.写代码：

ViewController.h

#import <UIKit/UIKit.h>@interface ViewController : UIViewController@end

ViewController.m

#import "ViewController.h"#import "ZBarSDK.h"@interface ViewController ()<ZBarReaderDelegate>@property (nonatomic, strong) UIImageView *imageView;@property (nonatomic, strong) UILabel *label;@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];        UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];    button.frame = CGRectMake(0, 600, self.view.bounds.size.width, 30);    [button setTitle:@"扫描" forState:UIControlStateNormal];    [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];    button.backgroundColor = [UIColor greenColor];    [button addTarget:self action:@selector(scan:) forControlEvents:UIControlEventTouchUpInside];    [self.view addSubview:button];           self.imageView = [[UIImageView alloc] initWithFrame:CGRectMake(110, 50, 100, 100)];    self.imageView.backgroundColor = [UIColor redColor];    [self.view addSubview:self.imageView];        self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 160, 320, 50)];    self.label.backgroundColor = [UIColor redColor];    [self.view addSubview:self.label];}- (void)scan:(UIButton *)btn{    ZBarReaderViewController *reader = [ZBarReaderViewController new];    reader.readerDelegate = self;    reader.supportedOrientationsMask = ZBarOrientationMaskAll;    ZBarImageScanner *scanner = reader.scanner;        [scanner setSymbology:ZBAR_I25 config:ZBAR_CFG_ENABLE to:0];    reader.showsZBarControls = YES;        [self presentViewController:reader animated:YES completion:nil];    }- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{    // ADD: get the decode results    id<NSFastEnumeration> results =    [info objectForKey: ZBarReaderControllerResults];    ZBarSymbol *symbol = nil;    for(symbol in results)        // EXAMPLE: just grab the first barcode        break;        // EXAMPLE: do something useful with the barcode data    self.label.text = symbol.data;        // EXAMPLE: do something useful with the barcode image    self.imageView.image =    [info objectForKey: UIImagePickerControllerOriginalImage];        // ADD: dismiss the controller (NB dismiss from the *reader*!)    [picker dismissViewControllerAnimated:YES completion:nil];}-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{    return (YES);}@end

注意：如果出现下面的问题

解决方法很简单：

是静态库不支持arm64，将Valid Architectures中得arm64去掉，然后将build Active Architectre only 设置为NO，就可以了

如图：
