Does anybody know how to change the brightness of a UIImageView in objective-C? Also, is there a way to increase/decrease the size of the UIImage ?

I'd like to animate a drawing sequence. My code draws a spiral into a UIImageView.image. The sequence changes the image contents, but also changes the scale of the surrounding UIImageView. The code is parameterized for the number of revolutions of the spiral: func drawSpiral(rotations:Double) { let scale = scaleFactor(rotations) // do some math to figure the best scale UIGraphicsBeginImageContextWithOptions(mainImageView.bounds.size, false, 0.0) let context = UIGraphicsGetCurrentContext()! context.scaleBy(x: scale, y: scale) // some animation prohibits changes! // ... drawing happens here
