Hello I am having a weird problem. I have a slider and a textfield with number formatter, both bound to a NSUserDefaultsController's "values" controller key and the "someVal" property.
I am also registering for notifications in the -viewDidLoad of the view controller: [[NSUserDefaults standardUserDefaults] addObserver:self forKeyPath: @"someVal" options:0 context:nil]; The problem is that observeValueForKeyPath is being called twice every time I move the slider or enter a new value in the edit. The viewDidLoad is executed only once (checked with an NSLog). It is easily reproducible. Why this might happen? macOS Sierra. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
