Cocoa osx NSTableview change row highlight color

Question:

Tag: osx,cocoa,colors,nstableview,highlight

In my application I have a view based NSTableView with one column. The highlight color of the rows is set to regular (blue). I need to change that color to my custom color. In the interface builder I tried changing it but the only options are "None, regular and source list".

I tried this post solution with no success: http://stackoverflow.com/a/9594543/3065901

I read that I have to use this delegate method but I dont know how to use this.

- (NSTableRowView *)tableView:(NSTableView *)tableView rowViewForRow:(NSInteger)row

I tried drawing the row in that method but i get invalid context warnings and the row still keeps with the same higlight. Please post a simple example of how to use this delegate method:

Need help please. Thanks in advance.

From this link.

MyNSTableRowView.h

#import <Cocoa/Cocoa.h>
@interface MyNSTableRowView : NSTableRowView
@end

MyNSTableRowView.m

#import "MyNSTableRowView.h"

@implementation MyNSTableRowView
- (id)init
{
    if (!(self = [super init])) return nil;
    return self;
}

- (void)drawSelectionInRect:(NSRect)dirtyRect {
     if (self.selectionHighlightStyle !=    NSTableViewSelectionHighlightStyleNone) {
     NSRect selectionRect = NSInsetRect(self.bounds, 2.5, 2.5);
     [[NSColor colorWithCalibratedWhite:.65 alpha:1.0] setStroke];
     [[NSColor colorWithCalibratedWhite:.82 alpha:1.0] setFill];
     NSBezierPath *selectionPath = [NSBezierPath bezierPathWithRoundedRect:selectionRect
                                                               xRadius:6 yRadius:6];
     [selectionPath fill];
     [selectionPath stroke];
     }
}
@end

AppDelegate.m
