Whether a window will appear or not has nothing to do with File's Owner. Your window is probably marked as "Release When Closed" in IB. It's shown once the first time, but after closing it it's deallocated and no longer exists so it can't be shown a second time. Turn that off. Documentation on File's Owner: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/LoadingResources/CocoaNibs/CocoaNibs.html In this case File's Owner is the NSWindowController because it's the NSWindowController that is loading and "owns" the nib. When you load a nib, your code needs to access certain objects in the nib (via IBOutlets) and your nib may need to set properties (like delegates, data sources, and actions) to objects that exist outside of the nib. When you connect to "File's Owner", you're connecting from an object in IB to that object that already exists before nib is loaded. When you connect from "File's Owner" to an object in the nib, you're setting an outlet in that already existing object to an object in the nib that's being loaded. -- Seth Willits _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
