x轴旋转:
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@”transform.rotation.x”];
theAnimation.duration=8;
theAnimation.removedOnCompletion = YES;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
[yourView.layer addAnimation:theAnimation forKey:@”animateTransform”];
y轴旋转:
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@”transform.rotation.y”];
theAnimation.duration=8;
theAnimation.removedOnCompletion = YES;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
[yourView.layer addAnimation:theAnimation forKey:@”animateTransform”];
z轴旋转:
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@”transform.rotation.z”];
theAnimation.duration=8;
theAnimation.removedOnCompletion = YES;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
[yourView.layer addAnimation:theAnimation forKey:@”animateTransform”];
以上缩放是以view的中心点为中心缩放的,如果需要自定义缩放点,可以设置卯点:
//中心点
[yourView.layer setAnchorPoint:CGPointMake(0.5, 0.5)];
//左上角
[yourView.layer setAnchorPoint:CGPointMake(0, 0)];
//右下角
[yourView.layer setAnchorPoint:CGPointMake(1, 1)];
可设参数:
theAnimation.repeatCount = 0;
theAnimation.autoreverses = NO;
旋转的另一种实现:(以下代码绕z轴旋转180度)
[self.topViewController.view.layer setAnchorPoint:CGPointMake(0.5, 0.5)];
[self.topViewController.view.layer setTransform:CATransform3DMakeRotation(0, 0, 0, 1)];
[UIView animateWithDuration:8 delay:0.0f options:UIViewAnimationOptionAllowUserInteraction | UIViewAnimationCurveEaseIn animations:^{
[self.topViewController.view.layer setTransform:CATransform3DMakeRotation(3.1415926, 0, 0, 1)];
} completion:^(BOOL finished) {
}];
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@”transform.rotation.x”];
theAnimation.duration=8;
theAnimation.removedOnCompletion = YES;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
[yourView.layer addAnimation:theAnimation forKey:@”animateTransform”];
