UIView摇动animation

我试图做一个UIView摇时按下button。

我正在修改我在http://www.cimgf.com/2008/02/27/core-animation-tutorial-window-shake-effect/上find的代码。

但是,通过尝试适应下面的代码摇动一个UIView,它不起作用:

- (void)animate { const int numberOfShakes = 8; const float durationOfShake = 0.5f; const float vigourOfShake = 0.1f; CAKeyframeAnimation *shakeAnimation = [CAKeyframeAnimation animation]; CGRect frame = lockView.frame; CGMutablePathRef shakePath = CGPathCreateMutable(); CGPathMoveToPoint(shakePath, NULL, CGRectGetMinX(frame), CGRectGetMinY(frame)); for (int index = 0; index < numberOfShakes; ++index) { CGPathAddLineToPoint(shakePath, NULL, CGRectGetMinX(frame) - frame.size.width * vigourOfShake, CGRectGetMinY(frame)); CGPathAddLineToPoint(shakePath, NULL, CGRectGetMinX(frame) + frame.size.width * vigourOfShake, CGRectGetMinY(frame)); } CGPathCloseSubpath(shakePath); shakeAnimation.path = shakePath; shakeAnimation.duration = durationOfShake; [lockView.layer addAnimation:shakeAnimation forKey:@"frameOrigin"]; } 

我写了这个post。 这是一个UIView矫枉过正,再加上参数适应OSX应用程序。 做这个,而不是。

 CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position"]; [animation setDuration:0.05]; [animation setRepeatCount:8]; [animation setAutoreverses:YES]; [animation setFromValue:[NSValue valueWithCGPoint: CGPointMake([lockView center].x - 20.0f, [lockView center].y)]]; [animation setToValue:[NSValue valueWithCGPoint: CGPointMake([lockView center].x + 20.0f, [lockView center].y)]]; [[lockView layer] addAnimation:animation forKey:@"position"]; 

你必须使用持续时间和repeatCount参数,以及from和center的x距离,但它应该给你你所需要的。 我希望有帮助。 如果您有任何问题,请告诉我。


Swift 3.0

 let animation = CABasicAnimation(keyPath: "position") animation.duration = 0.06 animation.repeatCount = 4 animation.autoreverses = true animation.fromValue = CGPoint(x: midX - 10, y: midY) animation.toValue = CGPoint(x: midX + 10, y: midY) layer.add(animation, forKey: "position") 

我更喜欢这个解决scheme有一个很好的弹性行为,非常适合错误的密码摇晃animation。

 view.transform = CGAffineTransformMakeTranslation(20, 0); [UIView animateWithDuration:0.4 delay:0.0 usingSpringWithDamping:0.2 initialSpringVelocity:1.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{ view.transform = CGAffineTransformIdentity; } completion:nil]; 

Swift 3

 extension UIView { func shake() { self.transform = CGAffineTransform(translationX: 20, y: 0) UIView.animate(withDuration: 0.4, delay: 0, usingSpringWithDamping: 0.2, initialSpringVelocity: 1, options: .curveEaseInOut, animations: { self.transform = CGAffineTransform.identity }, completion: nil) } } 

这是我的漂亮和简单的看版本这模拟了当你做一个不正确的login时在Mac OS X上得到的摇晃。 你可以添加这个作为UIView类别,如果你喜欢。

 @implementation UIView (DUExtensions) - (void) shake { CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"transform.translation.x"]; animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; animation.duration = 0.6; animation.values = @[ @(-20), @(20), @(-20), @(20), @(-10), @(10), @(-5), @(5), @(0) ]; [self.layer addAnimation:animation forKey:@"shake"]; } @end 

animation值是视图当前位置的x偏移量。 正值将视图向右移动,负值向左移动。 通过连续降低它们,你会得到一个动摇,自然失去动力。 你可以调整这些数字,如果你喜欢。

如果有人需要,这是一个扩展版本

 extension UIImageView{ func vibrate(){ let animation = CABasicAnimation(keyPath: "position") animation.duration = 0.05 animation.repeatCount = 5 animation.autoreverses = true animation.fromValue = NSValue(CGPoint: CGPointMake(self.center.x - 2.0, self.center.y)) animation.toValue = NSValue(CGPoint: CGPointMake(self.center.x + 2.0, self.center.y)) self.layer.addAnimation(animation, forKey: "position") } } 

这将animation一个小的UIImageView(约15×15)。 如果您需要制作更大的animation,您可能需要将动作的2.0因子更改为更大。

基于@bandejapaisa答案,Swift 3的UIView扩展

 extension UIView { func shake() { let animation = CAKeyframeAnimation(keyPath: "transform.translation.x") animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear) animation.duration = 0.6 animation.values = [-20, 20, -20, 20, -10, 10, -5, 5, 0] layer.addAnimation(animation, forKey: "shake") } } 

采取那一个: https : //github.com/jonasschnelli/UIView-I7ShakeAnimation

这很容易

你可以试试这段代码:

调用下面的代码,使用: [self earthquake:myObject];

 #pragma mark EarthQuake Methods - (void)earthquake:(UIView*)itemView { AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); CGFloat t = 2.0; CGAffineTransform leftQuake = CGAffineTransformTranslate(CGAffineTransformIdentity, t, -t); CGAffineTransform rightQuake = CGAffineTransformTranslate(CGAffineTransformIdentity, -t, t); itemView.transform = leftQuake; // starting point [UIView beginAnimations:@"earthquake" context:itemView]; [UIView setAnimationRepeatAutoreverses:YES]; // important [UIView setAnimationRepeatCount:3]; [UIView setAnimationDuration:0.05]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(earthquakeEnded:finished:context:)]; itemView.transform = rightQuake; // end here & auto-reverse [UIView commitAnimations]; } - (void)earthquakeEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { if ([finished boolValue]) { UIView* item = (UIView *)context; item.transform = CGAffineTransformIdentity; } } 

你可以在UIButton的click事件上调用这个方法

 -(void)shakescreen { //Shake screen CGFloat t = 5.0; CGAffineTransform translateRight = CGAffineTransformTranslate(CGAffineTransformIdentity, t, t); CGAffineTransform translateLeft = CGAffineTransformTranslate(CGAffineTransformIdentity, -t, -t); self.view.transform = translateLeft; [UIView animateWithDuration:0.05 delay:0.0 options:UIViewAnimationOptionAutoreverse|UIViewAnimationOptionRepeat animations:^ { [UIView setAnimationRepeatCount:2.0]; self.view.transform = translateRight; } completion:^(BOOL finished) { if (finished) { [UIView animateWithDuration:0.05 delay:0.0 options:UIViewAnimationOptionBeginFromCurrentState animations:^ { self.view.transform = CGAffineTransformIdentity; } completion:NULL]; } }]; } 

希望这会帮助你:-)

C#Xamarin.iOS版本的答案如何在iOS中创buildUIView动摇animation如下

  CAKeyFrameAnimation keyframeAnimation = CAKeyFrameAnimation.GetFromKeyPath(new NSString("transform.translation.x")); keyframeAnimation.TimingFunction = CAMediaTimingFunction.FromName(CAMediaTimingFunction.EaseInEaseOut); keyframeAnimation.Duration = 0.6f; keyframeAnimation.Values = new NSObject[]{ new NSNumber(-20f), new NSNumber(20f), new NSNumber(-20f), new NSNumber(20f), new NSNumber(-10f), new NSNumber(10f), new NSNumber(-5f), new NSNumber(5f), new NSNumber(0f) }; shakyView.Layer.AddAnimation(keyframeAnimation, "shake"); 

这是一个使用阻尼function衰减震动的:

 - (void)shake { CAKeyframeAnimation* animation = [CAKeyframeAnimation animationWithKeyPath:@"position"]; animation.duration = 0.5; animation.delegate = self; animation.fillMode = kCAFillModeForwards; animation.removedOnCompletion = YES; animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; NSMutableArray* values = [[NSMutableArray alloc] init]; int steps = 100; double position = 0; float e = 2.71; for (int t = 0; t < steps; t++) { position = 10 * pow(e, -0.022 * t) * sin(0.12 * t); NSValue* value = [NSValue valueWithCGPoint:CGPointMake([self center].x - position, [self center].y)]; DDLogInfo(@"Value: %@", value); [values addObject:value]; } animation.values = values; [[self layer] addAnimation:animation forKey:@"position"]; } 

你可以尝试下面的代码:

 + (void)vibrateView:(UIView*)view { CABasicAnimation *shiverAnimationR; shiverAnimationR = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; shiverAnimationR.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(1)]; //shiverAnimationR.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(-10)]; shiverAnimationR.duration = 0.1; shiverAnimationR.repeatCount = 1000000.0; // Use A high Value shiverAnimationR.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]; [view.layer addAnimation: shiverAnimationR forKey:@"shiverAnimationR"]; CABasicAnimation * shiverAnimationL; shiverAnimationL = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; //shiverAnimationL 2.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(10)]; shiverAnimationL.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(-1)]; shiverAnimationL.duration = 0.1; shiverAnimationL.repeatCount = 1000000.0; shiverAnimationL.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]; [view.layer addAnimation: shiverAnimationL forKey:@"shiverAnimationL"]; } 

从链接。

我重构了@Matt Long代码,并对UIView做了一个分类。 现在它更加可重用,易于使用。

 @implementation UIView (Animation) - (void)shakeViewWithOffest:(CGFloat)offset { CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position.x"]; [animation setDuration:0.05]; [animation setRepeatCount:6]; [animation setAutoreverses:YES]; [animation setFromValue:@([self center].x-offset)]; [animation setToValue:@([self center].x+offset)]; [self.layer addAnimation:animation forKey:@"position.x"]; } - (void)shake { [self shakeViewWithOffest:7.0f]; } @end 

这里是一个使用的版本,

 + (void)animateKeyframesWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewKeyframeAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion 

在iOS 7中引入。

  const CGFloat xDelta = 16.0f; [UIView animateKeyframesWithDuration:0.50f delay:0.0f options:UIViewKeyframeAnimationOptionCalculationModeLinear animations:^{ [UIView addKeyframeWithRelativeStartTime:0.0 relativeDuration:(1.0/6.0) animations:^{ self.passwordTextField.transform = self.usernameTextField.transform = CGAffineTransformMakeTranslation(xDelta, 0.0); }]; [UIView addKeyframeWithRelativeStartTime:(1.0/6.0) relativeDuration:(1.0/6.0) animations:^{ self.passwordTextField.transform = self.usernameTextField.transform = CGAffineTransformMakeTranslation(-xDelta, 0.0); }]; [UIView addKeyframeWithRelativeStartTime:(1.0/3.0) relativeDuration:(1.0/3.0) animations:^{ self.passwordTextField.transform = self.usernameTextField.transform = CGAffineTransformMakeTranslation(xDelta/2.0, 0.0); }]; [UIView addKeyframeWithRelativeStartTime:(2.0/3.0) relativeDuration:(1.0/3.0) animations:^{ self.passwordTextField.transform = self.usernameTextField.transform = CGAffineTransformIdentity; }]; } completion:NULL]; 

Swift 3实现基于@ Mihael-Isaev的答案

 private enum Axis: StringLiteralType { case x = "x" case y = "y" } extension UIView { private func shake(on axis: Axis) { let animation = CAKeyframeAnimation(keyPath: "transform.translation.\(axis.rawValue)") animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear) animation.duration = 0.6 animation.values = [-20, 20, -20, 20, -10, 10, -5, 5, 0] layer.add(animation, forKey: "shake") } func shakeOnXAxis() { self.shake(on: .x) } func shakeOnYAxis() { self.shake(on: .y) } }
