我希望图像在 imageview 上反复淡入淡出

Answer 1

采用： [UiView animateWithDuration:delay:options:animations:completion:]

然后fadeIn，FadeOut在完成时改变图像，再次fadeIn。但是如果你想要动画重叠，那么你应该使用 2 个 UIImageView。

Answer 2

UIImage * toImage = [UIImage imageNamed:@"myname.png"];
[UIView transitionWithView:self.view
              duration:5.0f
               options:UIViewAnimationOptionTransitionCrossDissolve
            animations:^{
              self.imageView.image = toImage;
            } completion:nil];
