我想要做的是能夠掃描QR碼，然後自動加載相關網頁。 我已經下載了Redlaser SDK，並在我有的時候儘可能多地檢查了它，而且我不明白的一點是SDK的實際方法在哪裏。在進入ZBar之前，我真的很想知道如何實現這個簡單的任務。iOS Redlaser SDK：試圖瞭解如何處理結果不同
這是SDK.h文件：

This function returns the version of the RedLaser SDK, as a NSString.

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.

問題的方法是doneScanning方法 - 其中該方法的實際體內發現的？根據我所知，沒有SDK的源文件，這是我需要在自己的應用程序中編輯的方法。
