NSTextContainer exclusionPaths setter无法识别？

Question

Sorry if the question looks trivial:

I'm trying to set a NSTextContainer instance property exclusionPaths using its underlying setter: [myNSTCInstance setExclusionPaths:arrayOfPaths]; and I systematically get:

-[NSTextContainer setExclusionPaths:]: unrecognized selector sent to instance 0x12b8410"

Since (for some reasons) I can't use the dot notation myNSTCInstance.exclusionPaths = , I was wondering how to set this property the more classic way?

Thanks for your help!

Answer 1

NSTextContainer on iOS has a exclusionPaths property, but NSTextContainer on OS X does not have this property. According to the documentation, you have to subclass NSTextContainer on OS X to define non-rectangular regions.

Answer 2

There are no reason that this does'n work. exclusionPaths is a property of NSTextContainer class.

1. Are you sure that your object is of type NSTextContainer ?

2. If Yes, try to remove your derived Data and relaunch Xcode.
