Description

You can't view either of these classes in the runtime browser. I debugged it and in the case of NSScrollView, it was because one of the methods uses a block implementation (imp_implementationWithBlock). This causes -[RTBMethod dyldInfo] to return nil because it can't get the linker address of a block.

This made the three props that rely on that method return nil (categoryName, symbolName, filePath). Not having those leads to several issues so I just made them return @"(null)" to work around it.

Research direction

Start at RTBMethod dyldInfo and trace the handling of methods created with imp_implementationWithBlock. Check how categoryName, symbolName, and filePath are used when this returns nil, then reproduce the issue by viewing NSView and NSScrollView in the runtime browser. Done means both classes are viewable without relying on the "(null)" workaround.
