我想要做的是能够扫描QR码，然后自动加载相关网页。 我已经下载了Redlaser SDK，并在我有的时候尽可能多地检查了它，而且我不明白的一点是SDK的实际方法在哪里。在进入ZBar之前，我真的很想知道如何实现这个简单的任务。iOS Redlaser SDK：试图了解如何处理结果不同
这是SDK.h文件：

NSString *RL_GetRedLaserSDKVersion();
/*******************************************************************************
RL_CheckReadyStatus()
This function returns information about whether the SDK can be used. It
doesn't give dynamic state information about what the SDK is currently doing.
Generally, positive values mean you can scan, negative values mean you
can't. The returned value *can* change from one call to the next.
If this function returns a negative value, it's usually best to design your
app so that it won't attempt to scan at all. If this function returns
MissingOSLibraries this is especially important, as the SDK will probably
crash if used. See the documentation.

问题的方法是doneScanning方法 - 其中该方法的实际体内发现的？根据我所知，没有SDK的源文件，这是我需要在自己的应用程序中编辑的方法。
