Question

I have no experience at all at objective-c, only now started.
A developer I work with had to go abroad for a few days, and by mistake left an error in the code, and now I cannot compile an Iphone application to finish it…

I got some information from him by mail, and he told me that he left a library that is called dialog and that I need to remove it to make it work…

The thing is that I have no experience in objective-c and Xcode… i’m the web developer 🙂

i tried to run the project, and got this error:

Build target mormar

after googling this for a while, I still have no idea how to solve this…
I would greatly appreciate any help,
thanks!

You need to link against QuartzCore.

Click on your project name in the Xcode sidebar. Then click on your target, and in the Summary tab find the list of linked frameworks and libraries. Click the plus button below this list, and add QuartzCore.
