Solution

  • I see the term cache in your code and taking some guesses:

    It looks like you are loading the images, then manipulating them and storing the manipulated images for later use. There are a number of things you need to take care of:

    First of all, make sure the current appearance is set correctly when you do your image loading/manipulation. Outside of drawRect: and a few other methods, you always need to do a dance similar to this:

    NSAppearance * savedAppearance = [NSAppearance currentAppearance];
[NSAppearance setCurrentAppearance:someView.effectiveAppearance];

// Do your image/color/drawing stuff.

[NSAppearance setCurrentAppearance:savedAppearance];

    Be aware that the appearance is "scoped" to a specific view! You can have different appearances in the same view hierarchy.

    You need to either override viewDidChangeEffectiveAppearance of your NSView or KVObserve the effectiveAppearance of a view to get notified about appearance changes and react accordingly (recreate your icons).
