动画旋转 UIImageView

问题描述

我想将 UIImageView 向左/向右旋转大约 10 度，但动画很流畅，而不是我看到的突然转弯:

I want to rotate a UIImageView by roughly 10 degrees left/right but have a smooth animation, rather than a sudden turn which I see using:

player.transform = CGAffineTransformMakeRotation(angle)

任何帮助表示赞赏，谢谢.

Any help appreciated, thanks.

推荐答案

我使用这样的一些代码来实现类似的效果(虽然我将它旋转了 360 度):

I use some code like this to achieve a similar effect (though I rotate it by 360 degrees):

CABasicAnimation *rotate;
rotate = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
rotate.fromValue = [NSNumber numberWithFloat:0];
rotate.toValue = [NSNumber numberWithFloat:deg2rad(10)];
rotate.duration = 0.25;
rotate.repeatCount = 1;
[self.view.layer addAnimation:rotate forKey:@"10"];

我使用与此非常相似的代码来旋转图像视图.

I use code very similar to this to spin an image view.
