常用动画

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];
