建立了一個cocoa?application項目，在Interface Builder中修改了title，在運行時標題始終是“Untitled”。

這是我在http://stackoverflow.com/questions/4720030/cocoa-mac-application-title-says-untitled上找的解決方法。

I have created a document based?Mac?OSX application, and when I'm editing in Interface Builder, the title is correct (I filled out that portion of the inspector) but once the program runs, the application title is 'Untitled'. How can I change it? In my IB Doc Window, I have instances of Files Owner, First Responder, NSApplication, and NSWindow. There is no view?controller, is that the issue? I'm new to Cocoa..

-> It will probably change to the name of your document once you save it (or open one). – zneak Jan 18 at 3:07

-> Naming a new, unsaved document “untitled” is the correct way according to the HIG.?http://developer.apple.com/library/mac/#documentation/UserExperience/Conceptual/AppleHIGuidelines/XHIGWindows/XHIGWindows.html#//apple_ref/doc/uid/20000961-CHDHBCGE?Why do you want to violate that convention? – Peter Hosey Jan 18 at 5:17

下面是比較暫時比較好的解決方法：覆蓋NSDocument的-displayName方法

One solution is to override -displayName in your NSDocument subclass:

- (NSString *)displayName {
????if (![self fileURL])
????????return @"Some custom untitled string";

????return [super displayName];
}

You can also check out NSWindowController's -windowTitleForDocumentDisplayName: if you're using custom window controllers.

如果有好的建議，歡迎提供，多謝～
