使用前

        需引入QuartzCore.framework, 并在相关文件中加入 #import "QuartzCore/QuartzCore.h"

定义

         shakeFeedbackOverlay为UIImageView

设置

         self.shakeFeedbackOverlay.alpha = 0.0;

         self.shakeFeedbackOverlay.layer.cornerRadius = 10.0; //设置圆角半径

1、图像左右抖动

    CABasicAnimation* shake = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

    shake.fromValue = [NSNumber numberWithFloat:-M_PI/32];

    shake.toValue = [NSNumber numberWithFloat:+M_PI/32];

    shake.duration = 0.1;

    shake.autoreverses = YES; //是否重复

    shake.repeatCount = 4;

    [self.shakeFeedbackOverlay.layer addAnimation:shake forKey:@"shakeAnimation"];

    self.shakeFeedbackOverlay.alpha = 1.0;

    [UIView animateWithDuration:2.0 delay:0.0 options:UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction animations:^{ self.shakeFeedbackOverlay.alpha = 0.0; //透明度变0则消失 } completion:nil];

2、图像顺时针旋转

    CABasicAnimation* shake = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

    shake.fromValue = [NSNumber numberWithFloat:0];

    shake.toValue = [NSNumber numberWithFloat:2*M_PI];

    shake.duration = 0.8; shake.autoreverses = NO;

    shake.repeatCount = 1;

    [self.shakeFeedbackOverlay.layer addAnimation:shake forKey:@"shakeAnimation"];

    self.shakeFeedbackOverlay.alpha = 1.0;

    [UIView animateWithDuration:10.0 delay:0.0 options:UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction animations:^{ self.shakeFeedbackOverlay.alpha = 0.0; } completion:nil];

3、图像关键帧动画 

    CAKeyframeAnimation *animation = [CAKeyframeAnimation animation];

    CGMutablePathRef aPath = CGPathCreateMutable();

    CGPathMoveToPoint(aPath, nil, 20, 20);

    CGPathAddCurveToPoint(aPath, nil, 160, 30, 220, 220, 240, 420);

    animation.path = aPath;

    animation.autoreverses = YES;

    animation.duration = 2;

    animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];

    animation.rotationMode = @"auto";

    [ballView.layer addAnimation:animation forKey:@"position"];

4、组合动画 CAAnimationGroup

    CABasicAnimation *flip = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];

    flip.toValue = [NSNumbernumberWithDouble:-M_PI];

    CABasicAnimation *scale= [CABasicAnimation animationWithKeyPath:@"transform.scale"];

    scale.toValue = [NSNumbernumberWithDouble:12];

    scale.duration = 1.5;

    scale.autoreverses = YES;

    CAAnimationGroup *group = [CAAnimationGroup animation];

    group.animations = [NSArray arrayWithObjects:flip, scale, nil];

    group.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

    group.duration = 3;

    group.fillMode = kCAFillModeForwards;

    group.removedOnCompletion = NO;

    [ballView.layer addAnimation:group forKey:@"position"];

5、指定时间内旋转图片

//启动定时器旋转光圈

- (void)startRotate

{

    self.rotateTimer = [NSTimer scheduledTimerWithTimeInterval:0.02

                                                  target:self

                                                selector:@selector(rotateGraduation)

                                                userInfo:nil

                                                 repeats:YES];

}

//关闭定时器

- (void)stopTimer

{

    if ([self.rotateTimerisValid])

{

        [self.rotateTimerinvalidate];

        self.rotateTimer = nil;

    }

}

//旋转动画

- (void)rotateGraduation

{

    self.timeCount--;

    if (self.timeCount == 0)

    {

        [self stopTimer];

        // doSomeThing //旋转完毕 可以干点别的

        self.timeCount = 25;

    }

    else

    {

        //计算角度 旋转

        static CGFloat radian = 150 * (M_2_PI / 360);

        CGAffineTransform transformTmp = self.lightImageView.transform;

        transformTmp = CGAffineTransformRotate(transformTmp, radian);

        self.lightImageView.transform = transformTmp;

    };

}

调用方法

self.timeCount = 25; //动画执行25次

[self startRotate];
