ios常用动画详解手机开发

使用block

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;

      self.shakeFeedbackOverlay.layer masksToBounds = YES;

1、图像左右抖动

      CABasicAnimation* shake =[CABasicAnimation animationWithKeyPath:@”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:shake forKey:@”shakeAnimation”];

     self.shakeFeedbackOverlay.alpha= 1.0;

    [UIView animateWithDuration:2.0delay: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 = [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:shake forKey:@”shakeAnimation”];

     self.shakeFeedbackOverlay.alpha= 1.0;

     [UIViewanimateWithDuration: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.layeraddAnimation: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 = [NSArrayarrayWithObjects:flip, scale, nil];

    group.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

     group.duration = 3;

     group.fillMode =kCAFillModeForwards;

    group.removedOnCompletion = NO;

     [ballView.layeraddAnimation: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 = [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

 [self startRotate];

 

1 2 3 4 5

最后那个 static CGFloat radian = 150 * (M_2_PI / 360);   应该改为 static CGFloat radian = 150 * (M_PI * 2 / 360);

//图片的淡入淡出

// 淡入显示新View

//   imgagee.alpha = 0.0f;

//   [UIView beginAnimations:@”fadeIn” context:nil];

     [self.view addSubview:imgagee];

//   [UIView setAnimationDuration:4.0];

//   imgagee.alpha = 1.0f;

//   [UIView commitAnimations];

   

   // 淡出移除当前View

   imgagee.alpha= 1.0f;

   [UIView beginAnimations:@”fadeIn” context:nil];

   [UIView setAnimationDuration:3];

   imgagee .alpha = 0.0f;

[UIView commitAnimations];

 

 

／／视图抖动动画

// 视图抖动动画

+ (void)shakeView:(UIView *)viewduration:(CGFloat)fDuration

{

    if (view && (fDuration>= 0.1f))

    {

        CABasicAnimation*shake = [CABasicAnimationanimationWithKeyPath:@”transform.rotation.z”];

        //设置抖动幅度

        shake.fromValue= [NSNumber numberWithFloat:-0.3];

        shake.toValue= [NSNumber numberWithFloat:+0.3];

        shake.duration= 0.1f;

        shake.repeatCount= fDuration/4/0.1f;

        shake.autoreverses= YES;

        [view.layeraddAnimation:shake forKey:@”shakeView”];

    }else{}

}
