I am working on a document-based OSX application, with master-detail style windows. I understand how to open additional windows, to display additional information, by using -makeWindowControllers and adding extra window controllers, but I can't set the title of the new windows. I have tried using -setTitle and -windowTitleForDocumentDisplayName in both Document.m and in my sub-classed window controller class, but I can't get the window title to change. How do I change the title of non-main-windows, which have a sub-classed window controller, in an NSDocument based application? EDIT: I know

I've created an .icns and set it in the Document Types section of my project, but my documents' icons in Finder remain generic. I've noticed that if I change my document type's file extension, the icon displays. Is there a cache I need to clear or some other way to update the icon without changing the file extension? To force refresh icon put this into your terminal /System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user; killall Dock Mavericks: /System/Library/Frameworks/CoreServices

Documentation simply states that setting setAutosavingDelay to anything > 0 on the shared doc controller should do it, but after calling [[NSDocumentController sharedDocumentController] setAutosavingDelay:2.0]; in my controller, autosave doesn't seem to work: I neither see anything in ~/Library/Autosave Information/ , nor is [[[NSDocumentController sharedDocumentController] currentDocument] autosavedContentsFileURL] initialized. Note that in my app, normal loading and saving work fine (keyedarchivers, nscoding-based class for my docs, etc). Have you overridden -updateChangeCount: at all? I'm

I'm building my first serious Cocoa app. It is a document based app using Core Data for persistent storage. Using the Xcode "New project" template options, my project started with a couple of default classes: MainMenu.xib (the main menu of my app) EventDocument.xib (the main window of my app) EventDocument.h and EventDocument.m (the persistent document class) I took the design from there and it all works rather nicely, however through another question I came across a Cocoa class NSDocumentController which I was not aware of. This class apparently offers default logic for managing document

I have an NSDocument based app with autosave enabled. I'd like to prevent this popup from showing: I have tried returning nil from NSWindow's –title, –representedFilename and –representedURL which hide the title effectively hide the title but have no effect on the downward facing disclosure indicator and the popup. Is there a way I can prevent this popup from being presented? I was able to prevent the button from being shown by overriding NSWindow's + (NSButton *)standardWindowButton:(NSWindowButton)windowButtonKind forStyleMask:(NSUInteger)windowStyle and returning nil for
