在 cocos2d 引擎中实现二维码阅读器 [英] Implementing a QR reader in a cocos2d engine

问题描述

到目前为止，我正在使用 cocos2d 引擎创建一个游戏，并且我想实现一个二维码阅读器.

So far I am using the cocos2d engine to create a game and I want to implement a QR reader.

到目前为止，我已经创建了一个 CCScene，CCScene 有一个菜单按钮，它会导致一个 onScan 方法:

So far I've created a CCScene, the CCScene has a menu button and it leads to a onScan Method:

-(void) onScan:(id)sender{
    // ADD: present a barcode reader that scans from the camera feed
    ZBarReaderViewController *reader = [ZBarReaderViewController new];
    reader.readerDelegate = self;

    ZBarImageScanner *scanner = reader.scanner;
    // TODO: (optional) additional reader configuration here

    // EXAMPLE: disable rarely used I2/5 to improve performance
    [scanner setSymbology: ZBAR_I25
                   config: ZBAR_CFG_ENABLE
                       to: 0];

    // present and release the controller
    [self presentModalViewController: reader
                            animated: YES];
    [reader release];
}

我知道这适用于标准 ViewController 类，但我想知道如何最好地实现它以与我的 CCScene 上的 cocos2d 引擎一起工作

I understand that this works on a standard ViewController class but I am wondering how to best implement this to work with the cocos2d engine on my CCScene

任何帮助将不胜感激谢谢！

Any help would be appreciated Thanks!

推荐答案

UIView* glView = [CCDirector sharedDirector].view;
UIView* window = glView.superview;

[window addSubview:reader.view];
