Thus, you have to install the command line tool first before using the Cocoa app, or else the app won't function. Can anyone point me to some documentation (hopefu...

The only way I found to do this in Cocoa would be using the representationUsingType:properties: method of NsBitmapImageRep but unfortunatley I cannot use this method because it is not supported by cocotron (an open source API that implem...
I have an NSTextField which uses as an extended NSTextFieldCell, which creates a custom field editor, that intercepts and records key events. (Knowing the key events is important for the application, but the text field is still supposed to work as usual, by calling the [super ...] method). This is what the official documentation suggests...

In a Document-based Cocoa application, handled file extensions are listed in the application's Info.plist file. The application I'm building will require a loadable bundle for each type of file it opens. As such, I'd like the presence of bundles to modify the way my application registers itself as handling certain file types. As an ex...
I want to show the number of characters left for a new tweet, after a key has been lifted. Currently, this only happens if return is lifted: - (IBAction)updateCharacterCountFromNewTweetField:(id)sender { [newTweetCharacterCount setIntValue:140 - [[sender stringValue] length]]; } This action is connected to an NSTextField (NOT A UITe...
I'm creating an application and I don't want a title bar: If the title remains the same all the time, does it make sense to show it? For example, if an app doesn’t show the names of documents, or any other assets that it opens, and there is plenty of space at the top around other controls to grab onto if you want to move the window a...
