Question

Answer 1

在您的UIView动画过程中编写以下代码。

YourView.backgroundColor = [UIColor redColor];

Answer 2

Try this.

[UIView animateWithDuration:2.0 animations:^ {

    //other animations

    self.view.backgroundColor = [UIColor redColor];
}
completion:nil];

Answer 3

I don't think you can animate color like that (with animateWithDuration...). You would have to use a timer and iterate over a series of colors. You could use colorWithHue:saturation:brightness:alpha: for instance, and increment the hue value.
