Necessary to have Retina and non-Retina for all images in iOS App?

Currently , all the UIImageViews in my app are set to scaleToFill mode, using only one retina image without setting any non-retina image. I suppose that on non-retina display, the extra resolution will be lost by itself.

Question: Is this approach acceptable? And will Apple disapprove my app due to the missing non-retina images for UIImageView?

Apple won't reject your app. However it's recommended to have non-retina versions if you're targeting Universal devices, since there are still lot of non-retina iPad out there, and scaling is slower and sometimes produces ugly images.

If you're targeting iPhone only, (IMO) there's no need for non-retina images.
