如何在我自己的应用程序中集成QR码阅读器.

Question

我正在开发一个应用程序,其中我需要添加QR代码阅读器功能,这应该是这样的事情,我需要在主页上有一个图标,并通过单击该图标QR reader应该工作.我用谷歌搜索它,发现ZBarCoderReader很好用,但我陷入了整合这个SDK的困境.任何人都可以帮助集成此SDK.我知道我必须使用以下链接来集成此SDK. http://zbar.sourceforge.net/iphone/sdkdoc/install.html http://zbar.sourceforge.net/iphone/sdkdoc/camera.html

任何帮助将不胜感激.

Answer 1

• 1.从此链接下载ZBar SDK
• 2.打开dmg并将ZBarSDK文件夹复制到您的文件夹中project directory.
• 3.在XCode中右键单击您的项目,然后选择"将文件添加到您的项目名称"并添加ZBarSDK framework.
• 4.现在转到Build Phases并展开Link Binary With Libraries并添加以下附加框架
  • AVFoundation.framework
  • CoreMedia.framework
  • CoreVideo.framework
  • QuartzCore.framework
  • libiconv.dylib

然后

导入头文件

#import "ZBarSDK.h"

在图标按钮的触摸上添加以下代码:

- (IBAction)iconButtonTouchEvent:(id)sender {

    ZBarReaderViewController *reader = [ZBarReaderViewController new];
    reader.readerDelegate = self;
    reader.supportedOrientationsMask = ZBarOrientationMaskAll;

    //Hide Info Button at Right bottom and Show only Cancel Button at Left Bottom
    float currentVersion= 5.1;
    float sysVersion = [[[UIDevice currentDevice]systemVersion]floatValue];

    UIView * infoButton;
    if (sysVersion > currentVersion) {
        infoButton = [[[[[reader.view.subviews objectAtIndex:1] subviews] objectAtIndex:0] subviews] objectAtIndex:3];
     }
     else {
        infoButton = [[[[[reader.view.subviews objectAtIndex:1] subviews] objectAtIndex:0] subviews] objectAtIndex:2];
     }
    [infoButton setHidden:YES];

    ZBarImageScanner *scanner = reader.scanner;
    [scanner setSymbology: ZBAR_I25 config: ZBAR_CFG_ENABLE to: 0];

    [self presentModalViewController: reader animated: YES];
}

#pragma mark - Barcode Delegate Methods

- (void)imagePickerController: (UIImagePickerController*) reader didFinishPickingMediaWithInfo: (NSDictionary*) info{

    id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults];

    ZBarSymbol *symbol = nil;

    for(symbol in results)
        break;

    NSLog(@"Barcode Data = %@", symbol.data);

    [reader dismissModalViewControllerAnimated: YES];
}
