maybe this is not correct...I get the following warning when building a static
library that depends on gfx:
-dynamic not specified the following flags are invalid: -ObjC

Should any target that uses this new NSString category depend on ui/ios.gyp:ios
explicitly?

The ui/ gyp files aren't set up the way they used to be, and I'm not used to the
pattern they are using. It looks like yes, in this model.

changed to link_settings in the ui_ios.gyp file.
