Try adding a NSDictionaryController.xib file to you, and then bind its Controller contents to your dictionary in the user's default settings. Then you can bind the values ​​of the text field to the dictionary controller (layoutObjects).

// Assume 'anObjectController' is an NSObjectController.
// Assume 'userDefaultsController' is [NSUserDefaultsController sharedUserDefaultsController]

[self.anObjectController

    toObject:userDefaultsController 
    withKeyPath:@"values.someDictionary"
    options:@{NSHandlesContentAsCompoundValueBindingOption: @YES}];

NSContentObjectBinding NSContentBinding. NSObjectController contentObject. , .

This is not an easy mistake, because the end of the Xcode code automatically jumps to NSContentBinding, and this is one of the most commonly used binding names. It just cost me a lot of trouble, so I hope I saved something for someone else.
