本文详细介绍了一种在iOS应用中实现条形码扫描的方法，包括导入必要的SDK和框架、设置扫描视图、添加动画效果及处理扫描结果等关键步骤。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

导入ZBarSDK文件并引入一下框架
AVFoundation.framework
CoreMedia.framework
CoreVideo.framework
QuartzCore.framework
libiconv.dylib
引入头文件#import “ZBarSDK.h”即可使用
当找到条形码时，会执行代理方法
废话不多说,直接上代码

import "LQXZBarViewController.h"

@interface LQXZBarViewController ()
{
BOOL is_Anmotion;
ZBarReaderViewlqxreadview;
UIImageViewlqxscanZomeBack;
UIImageView*lqxreadLineView;
}
@end

@implementation LQXZBarViewController

(void)viewDidLoad {
[super viewDidLoad];
[self InitScan];
[self loopDrawLine];
}

pragma mark 初始化扫描
(void)InitScan
{
lqxreadview = [ZBarReaderView new];
lqxreadview.backgroundColor = [UIColor clearColor];
lqxreadview.frame = CGRectMake(187.5 - 150, 333.5 - 150, 300, 300);
lqxreadview.readerDelegate = self;
lqxreadview.allowsPinchZoom = YES;//使用手势变焦
lqxreadview.trackingColor = [UIColor redColor];
lqxreadview.showsFPS = NO;// 显示帧率 YES 显示 NO 不显示
lqxreadview.scanCrop = CGRectMake(50, 50, 50, 50);//将被扫描的图像的区域

UIImage *hbImage=[UIImage imageNamed:@"框.png"];
lqxscanZomeBack=[[UIImageView alloc] initWithImage:hbImage];
//添加一个背景图片
CGRect mImagerect=CGRectMake((lqxreadview.frame.size.width-200)/2.0, (lqxreadview.frame.size.height-200)/2.0, 200, 200);
[lqxscanZomeBack setFrame:mImagerect];
lqxreadview.scanCrop = [self getScanCrop:mImagerect readerViewBounds:lqxreadview.bounds];//将被扫描的图像的区域

[lqxreadview addSubview:lqxscanZomeBack];
[lqxreadview addSubview:lqxreadLineView];
[self.view addSubview:lqxreadview];
[lqxreadview start];

}

pragma mark 获取扫描区域

-(CGRect)getScanCrop:(CGRect)rect readerViewBounds:(CGRect)readerViewBounds
{
CGFloat x,y,width,height;

x = rect.origin.x / readerViewBounds.size.width;
y = rect.origin.y / readerViewBounds.size.height;
width = rect.size.width / readerViewBounds.size.width;
height = rect.size.height / readerViewBounds.size.height;

return CGRectMake(x, y, width, height);

}

pragma mark 扫描动画

-(void)loopDrawLine
{

CGRect  rect = CGRectMake(lqxscanZomeBack.frame.origin.x, lqxscanZomeBack.frame.origin.y, lqxscanZomeBack.frame.size.width, 2);
if (lqxreadLineView) {
    [lqxreadLineView removeFromSuperview];
}
lqxreadLineView = [[UIImageView alloc] initWithFrame:rect];
lqxreadLineView.backgroundColor = [UIColor redColor];
[lqxreadLineView setImage:[UIImage imageNamed:@"线.jpg"]];
[UIView animateWithDuration:3.0
                      delay: 0.0
                    options: UIViewAnimationOptionCurveEaseIn
                 animations:^{
                     //修改fream的代码写在这里
                     lqxreadLineView.frame =CGRectMake(lqxscanZomeBack.frame.origin.x, lqxscanZomeBack.frame.origin.y+lqxscanZomeBack.frame.size.height, lqxscanZomeBack.frame.size.width, 2);
                     [lqxreadLineView setAnimationRepeatCount:0];
                     
                 }
                 completion:^(BOOL finished){
                     if (!is_Anmotion) {
                     
                         [self loopDrawLine];
                     }
                     
                 }];

[lqxreadview addSubview:lqxreadLineView];

}

pragma mark 获取扫描结果

(void)readerView:(ZBarReaderView )readerView didReadSymbols:(ZBarSymbolSet )symbols fromImage:(UIImage )image
{
// 得到扫描的条码内容
const zbar_symbol_t symbol = zbar_symbol_set_first_symbol(symbols.zbarSymbolSet);
NSString *symbolStr = [NSString stringWithUTF8String: zbar_symbol_get_data(symbol)];
if (zbar_symbol_get_type(symbol) == ZBAR_QRCODE) {
```
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:symbolStr]];
```
}

for (ZBarSymbol *symbol in symbols) {
break;
}

[readerView stop];
is_Anmotion = YES;
[readerView removeFromSuperview];

}

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

// In a storyboard-based application, you will often want to do a little preparation before navigation

(void)prepareForSegue:(UIStoryboardSegue )segue sender:(id)sender {
// Get the new view controller using [segue destinationViewController].
// Pass the selected object to the new view controller.
}
/
