KVO Blocks In Action

Newer Older

See: toxicsoftware.com/kvoblocks/

All updates to the UI items (the layers in the central "map" view, the colour of the "star" when the picker is on screen, etc) are based on KVO blocks.

    This is the code that updates the star colour based on the user picking a colour (all CoreData/Cocoa Bindings/CoreAnimation/KVO Blocks):

    void *theUpdateObjectBlock = ^(NSString *keyPath, CGameObjectLayer *self, NSDictionary *change, id userInfo)
    {
    for (CALayer *theLayer in self.sublayers)
    [theShaderLayer setNeedsDisplay];
    };
    [theGameObjectLayer addKVOBlock:theUpdateObjectBlock forKeyPath:@"gameObject.color" options:0 identifier:@"KVO_IDENTIFIER_XX"];
