copied!<p>I am posting this in order to make things simple for newbies like me that are integrating zxing qr reader in their projects and to bring closure to a couple of threads related to zxing integration. </p> <p>1. Main thing - Be absolutely sure you have the latest version. </p> <blockquote> <p><a href="http://zxing.googlecode.com/svn/trunk/" rel="nofollow">http://zxing.googlecode.com/svn/trunk/</a></p> </blockquote> <p>[By now, January 18th, you will have no more issues with that zxing/common/ folder. Easiest fix for this: get the latest code!]</p> <p>2. Go to zxing -> iphone -> ZXingWidget. </p> <blockquote> <p>Drag ZXingWidget.xcodeproj file and drop it onto the root of your Xcode project's "Groups and Files" sidebar. </p> </blockquote> <p>[you should now have ZXingWidget.xcodeproj listed there and it has to drop down and list it's content]</p> <p>3. In the same place, project navigator, select: </p> <blockquote> <p>Your project file - > Targets -> 'your project name' -> Build phases -> Link binary with libraries.</p> <p>You should find a folder named 'Workspace'. Add 'libZXingWidget.a' from within.</p> </blockquote> <p>4. Still in Build phases, expand Target Dependencies and add ZXingWidget.</p> <p>5. Select Build Settings and search for Header Search Paths. You need to add 2 records to Header Search Paths. You do not need to associate values to User Header Search Paths. You achieve this by double clicking the column on the right. A small popover window will apear. Use the + button to add the first record. Add: </p> <blockquote> <p>../zxing/iphone/ZXingWidget/Classes</p> </blockquote> <p>Now use the + button to add the second record. Add: </p> <blockquote> <p>../zxing/cpp/core/src</p> </blockquote> <p>These are the values I use. These values work because I use the same folder to host both my project and the zxing folder. </p> <p>[Be sure to refer your folder properly in case you decide to have a different file structure.]</p> <p>6. Go back to Build Phases and add the following ios frameworks required: </p> <blockquote> <p>AVFoundation</p> <p>AudioToolbox</p> <p>CoreVideo</p> <p>CoreMedia</p> <p>libiconv</p> <p>AddressBook</p> <p>AddressBookUI</p> </blockquote> <p>7.</p> <blockquote> <p>Create a set of files (.h&.m) and change it's .m extension to .mm</p> </blockquote> <p>8. Test the integration by including the following in the file previously created: </p> <pre><code>#import <ZXingWidgetController.h> #import <QRCodeReader.h> </code></pre> <p>At this point you should run into missing files only if you are not running the latest version. Hope this helps.</p>
