In macOS 10.14 you can detect when the system theme has changed by listening to the following notification:
[NSDistributedNotificationCenter.defaultCenter addObserver: self
selector: @selector(OSThemeChanged:)
name: @"AppleInterfaceThemeChangedNotification"
object: nil];
But this does not get fired when the Accent color
changes (NSColor.controlAccentColor). I have an image I want to modify based on the accent color, so I would like to know when it changes.
Has anyone been able to figure this out?
AppleColorPreferencesChangedNotification
key should work I believe:
[[NSDistributedNotificationCenter defaultCenter] addObserver:self
selector:@selector(accentColorChanged:)
name:@"AppleColorPreferencesChangedNotification"
object:nil];
Notification isn't sent until the preference is changed and the system preferences general window is closed.
Couldn't find the documentation to link to for it though.
