Change NSTableView alternate row colors

Found a better way to do it here. That method overrides the highlightSelectionInClipRect: method in an NSTableView subclass so you can use any color you want for the alternating rows. It's not as hackish as using an NSColor category, and it only affects table views you choose.

If you want to use an undocumented way, make a NSColor category and override _blueAlternatingRowColor like this:

@implementation NSColor (ColorChangingFun)

+(NSColor*)_blueAlternatingRowColor
{
    return [NSColor redColor];
}

@end

or to change both colors, override controlAlternatingRowBackgroundColors to return an array of colors you want alternated.

@implementation NSColor (ColorChangingFun)

+(NSArray*)controlAlternatingRowBackgroundColors
{
    return [NSArray arrayWithObjects:[NSColor redColor], [NSColor greenColor], nil];
}

@end
