iphone - UIImageView Animation delay between frames?

I am trying to create an animation using a UIImageView with an array if images. It works great, except that I need a different delay between some of the frames. In an animated gif you can set the delay between frames. Every example I see of an animated UIImageView has a fixed delay between images.

Does anyone know how I can set a different delay between frames? Or, is there an example of such?

Maybe UIImageView is not the right thing to use, so if anyone has an alternative please let me know.

I have posted a similiar question in other forums and no one seems to be able to answer this. It seems like it should bo doable, since .gif images have had this forever.

Thanks

It may seem hacky, but:

From UIImageView documentation:

animationImages

An array of UIImage objects to use for an animation.

@property(nonatomic, copy) NSArray *animationImages

Discussion

The array must contain UIImage objects. You may use the same image object more than once in the array. Setting this property to a value other than nil hides the image represented by the image property. The value of this property is nil by default.

So you need to add your UIImage several times to the array for a delay.
