动画旋转 UIImageView

我想旋转一个UIImageView左/右大约 10 度，但有一个平滑的动画，而不是我看到的突然转向：

player.transform = CGAffineTransformMakeRotation(angle)

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.25]; // Set how long your animation goes for
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

player.transform = CGAffineTransformMakeRotation(angle); // if angle is in radians

// if you want to use degrees instead of radians add the following above your @implementation
// #define degreesToRadians(x)(x * M_PI / 180)
// and change the above code to: player.transform = CGAffineTransformMakeRotation(degreesToRadians(angle));

[UIView commitAnimations];

// The rotation code above will rotate your object to the angle and not rotate beyond that.
// If you want to rotate the object again but continue from the current angle, use this instead:
// player.transform = CGAffineTransformRotate(player.transform, degreesToRadians(angle));
