Combining the answers here and updating for IOS7:

-(void)drawMapRect:(MKMapRect)mapRect zoomScale:(MKZoomScale)zoomScale inContext:(CGContextRef)context
{
    [super drawMapRect:mapRect zoomScale:zoomScale inContext:context];

    UIGraphicsPushContext(context);
    CGContextSaveGState(context);
    [[UIColor blueColor] set];

    NSDictionary *fontAttributes = @{NSFontAttributeName:[UIFont systemFontOfSize:10.0f * MKRoadWidthAtZoomScale(zoomScale)]};
    CGSize size = [[[self overlay] title] sizeWithAttributes:fontAttributes];
    CGFloat height = ceilf(size.height);
    CGFloat width  = ceilf(size.width);

    CGRect circleRect = [self rectForMapRect:[self.overlay boundingMapRect]];
    CGPoint center = CGPointMake(circleRect.origin.x + circleRect.size.width /2, circleRect.origin.y + circleRect.size.height /2);
    CGPoint textstart = CGPointMake(center.x - width/2, center.y - height /2 );

    [[[self overlay] title] drawAtPoint:textstart withAttributes:fontAttributes];

    CGContextRestoreGState(context);
    UIGraphicsPopContext();
}
