Question

I’m getting this error when building in Xcode for iOS.

Undefined symbols for architecture i386:
"_CGRectInset", referenced from:
  -[RootViewController viewDidLoad] in RootViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The app is a clean project, just built from the template Xcode provides.

Any ideas?

I had the same problem with a project created from “Page-Based Application” template, in XCode4 Developer Preview 5.

You can fix it by adding the CoreGraphics framework to the list of linked frameworks and libraries. In other words:

1. Select the project file in the navigator (left-pane)
2. select the app target (the only other one is a testing target)
3. In the summary tab, scroll down to “Linked Frameworks and Libraries”
4. Hit the + andd CoreGraphics.framework.

Then it builds and runs.
