iosuitableviewindicatoraccessory

Which is the best way to change the color/view of disclosure indicator accessory view in a table view cell in iOS?

I need to change the color of the disclosureIndicatorView accessory in a UITableViewCell. I think there are two ways to get this done, but I'm not able to figure out which one's the optimum. So here is what I think I can do.

There is a property of UITableViewCell - accessoryView. So I can use setAccessoryView:(UIView *)view and pass view as the UIImageView holding the image that I want.

I have written an utility class which creates the content view (stuff like background color, adding other stuff, etc) for my cell and I add this content view to the cell in UITableViewDelegate. The other option is to draw a UIImage overriding the drawRect method of CustomContentView utility class.

Performing option 1 - I can get the things done the apple way. Just give them the view and they do the rest. But I guess adding a new UIView object to every row might turn out to be a heavy object allocation and decreasing the frame rate. As compared to just a UIImage object in my contentView. I believe UIImage is lighter than UIView.

Please throw some light people and help me decide over it.

    Drawing an image directly will almost certainly have better performance than adding a subview. You have to determine if that extra performance is necessary. I've used a few accessory views for custom disclosure indicators on basic cells and performance was fine. However, if you're already doing custom drawing for the content rect, it might not be that difficult to do the accessory view also.
