Add zxing to XCode 4

I am adding zxing to my project.

• I first copied the iphone folder to my project directory.

• Then copied the cpp folder to my project directory.

• Dragged the ZXingWidget.xcodeproj into XCode.

• Added the dependency.

• Linked the library.

• Now for header search paths, I don't know what to put. Here's what my setup looks like:

  

For header search paths, I entered:

• “zxing/iphone/ZXingWidget/Classes"
• “zxing/cpp/core/src/”

But when I try to import QRCodeReader.h it's telling me it's not found. So I am guessing it has 开发者_如何学运维something to do with header search paths. Can someone firm that the paths I entered are correct? If not, what could be wrong? Thanks.

Be sure that Recursive check box has been checked in Build Settings where ZXingWidget/Classes are added to the Header Search Paths.
