imageView.layer.cornerRadius =  2.0f;
imageView.image = [[DSFavIconManager sharedInstance] iconForURL:url completionBlock:^(UIImage *icon) {

Using apple touch icon fall-back for high resolution displays

[DSFavIconManager sharedInstance].useAppleTouchIconForHighResolutionDisplays = YES;
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 16.0f, 16.0f)];
imageView.layer.cornerRadius =  2.0f;
imageView.image = [[DSFavIconManager sharedInstance] iconForURL:url completionBlock:^(UIImage *icon) {
    imageView.image = icon;
    // Apple touch icons usually are designed for rounded corners.
    imageView.layer.masksToBounds = (icon.size.width / icon.scale) > 16.0f;
}];

Updating an activity indicator

[AFNetworkActivityIndicatorManager sharedManager].enabled = true;
[[NSNotificationCenter defaultCenter] addObserverForName:kDSFavIconOperationDidStartNetworkActivity object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *note) {
    [[AFNetworkActivityIndicatorManager sharedManager] incrementActivityCount];
