I have problem including ZXing in my App. I get error: "iostream file not found". I have done everything like in ZXing instruction but i can't get this working. I'm including this in .mm file. I use story boards this project is for iOS 6.0 This is error i get:

In file included from /Users/adam/Developer/project/project/SecondViewController.mm:11: In file included from zxing/iphone/ZXingWidget/Classes/QRCodeReader.h:10: In file included from zxing/iphone/ZXingWidget/Classes/FormatReader.h:22: zxing/cpp/core/src/zxing/common/Counted.h:23:10: fatal error: 'iostream' file not found

Any idea what can i do to get this working?

EDIT:

When i select Compile Source File As Objcetive-C++ project comiples without issues, BUT as i was told this is not god soultion beacuse this can make some problems later on with other parts of app.

Just rename your implementation file with .mm extension instead of .m solve the issue.
