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 = [CABasicAnimationanimationWithKeyPath:@"transform.rotation.z"];

 

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

 

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

 

    shake.duration= 0.1;

 

    shake.autoreverses= YES;//是否重复

 

    shake.repeatCount= 4;

 

    [self.shakeFeedbackOverlay.layeraddAnimation:shakeforKey:@"shakeAnimation"];

 

    self.shakeFeedbackOverlay.alpha= 1.0;

 

    [UIViewanimateWithDuration:2.0delay:0.0options:UIViewAnimationOptionCurveEaseIn| UIViewAnimationOptionAllowUserInteractionanimations:^{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 = [CABasicAnimationanimationWithKeyPath:@"transform.rotation.z"];

 

    shake.fromValue= [NSNumbernumberWithFloat:0];

 

    shake.toValue= [NSNumbernumberWithFloat:2*M_PI];

 

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

 

    shake.repeatCount= 1;

 

    [self.shakeFeedbackOverlay.layeraddAnimation:shakeforKey:@"shakeAnimation"];

 

    self.shakeFeedbackOverlay.alpha= 1.0;

 

    [UIViewanimateWithDuration:10.0delay:0.0options:UIViewAnimationOptionCurveEaseIn| UIViewAnimationOptionAllowUserInteractionanimations:^{self.shakeFeedbackOverlay.alpha= 0.0; } completion:nil];

 

3、图像关键帧动画

 

    CAKeyframeAnimation*animation = [CAKeyframeAnimationanimation];

 

    CGMutablePathRefaPath = 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= [CAMediaTimingFunctionfunctionWithName:kCAMediaTimingFunctionEaseOut];

 

    animation.rotationMode= @"auto";

 

    [ballView.layeraddAnimation:animationforKey:@"position"];

 

4、组合动画CAAnimationGroup

 

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

 

    flip.toValue= [NSNumbernumberWithDouble:-M_PI];

 

     

 

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

 

    scale.toValue= [NSNumbernumberWithDouble:12];

 

    scale.duration= 1.5;

 

    scale.autoreverses= YES;

 

     

 

    CAAnimationGroup*group = [CAAnimationGroupanimation];

 

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

 

    group.timingFunction= [CAMediaTimingFunctionfunctionWithName:kCAMediaTimingFunctionEaseInEaseOut];

 

    group.duration= 3;

 

    group.fillMode= kCAFillModeForwards;

 

    group.removedOnCompletion= NO;

 

    [ballView.layeraddAnimation:groupforKey:@"position"];

 

5、指定时间内旋转图片

 

//启动定时器旋转光圈

 

- (void)startRotate

 

{

 

    self.rotateTimer= [NSTimerscheduledTimerWithTimeInterval: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)

 

    {

 

        [selfstopTimer];

 

        // doSomeThing //旋转完毕 可以干点别的

 

        self.timeCount= 25;

 

    }

 

    else

 

    {

 

        //计算角度 旋转

 

        staticCGFloat radian = 150* (M_2_PI/ 360);

 

        CGAffineTransformtransformTmp = self.lightImageView.transform;

 

        transformTmp = CGAffineTransformRotate(transformTmp, radian);

 

        self.lightImageView.transform= transformTmp;

 

    };

 

}

 

调用方法

 

self.timeCount= 25;//动画执行25次

 

[selfstartRotate];

  最后那个

  staticCGFloat radian = 150* (M_2_PI/ 360);

   

  应该改为

  staticCGFloat radian = 150* (M_PI* 2/ 360);
