Custom view for star ratings

[Innovation]

I am writing a book application which allows users to rate books on a 1 - 5 star scale. I need a custom View for implementing this. I am thinking of doing this by using a subclass of UIImageView and detecting the tap location tap within the view and swapping in active or inactive stars to indicate the rating. Has anyone done something like this before of is there a better way of doing this?

Thanks.

I guess, instead of subclassing imageView it would be better if you subclass UIView.
Have 5 imageView objects in it for 5 stars and detect touches using CGRectContainsPoint.
This would help you create a generalized custom view which you could use in some of your other apps also... as it is!!!!

I havent implemented this yet, but would have done it the way mentioned above if required....

Thanks for the suggestion Akshay. I implemented it the way you said but for detecting touches i just used locationInView of the parent ratings view and set the imageView images to either bright or dark stars depending on the x position. Works great

Instead of UIImageView, Why not you use UIButton with custom image?
