iphone – 如何使“摇动”动画

概述在我的xcode项目中，我有一个UIImage。我想让它摇摆(动画)从左到右一点点。我写了这段代码，但是它不起作用。 -(void)errorShake{ [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.0]; [lockImage setTransform:CGAf 在我的xcode项目中，我有一个UIImage。我想让它摇摆(动画)从左到右一点点。我写了这段代码，但是它不起作用。

-(voID)errorShake{    [UIVIEw beginAnimations:nil context:NulL];    [UIVIEw setAnimationDuration:1.0];    [lockImage settransform:CGAffinetransformMakeRotation(-5 * M_PI / 180.0)];    [lockImage settransform:CGAffinetransformMakeRotation(-10 * M_PI / 180.0)];    [lockImage settransform:CGAffinetransformMakeRotation(-15 * M_PI / 180.0)];    [lockImage settransform:CGAffinetransformMakeRotation(-20 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(-15 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(-10 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(-5 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(0 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(5 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(10 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(15 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(20 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(15 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(10 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(5 * M_PI / 180.0)];     [lockImage settransform:CGAffinetransformMakeRotation(0 * M_PI / 180.0)];    [UIVIEw commitAnimations];}

请你告诉我，我怎么能让我的图像震动？

解决方法 这是我用于这个效果的代码。

-(voID)shakeVIEw {        CABasicAnimation *shake = [CABasicAnimation animationWithKeyPath:@"position"];        [shake setDuration:0.1];        [shake setRepeatCount:2];        [shake setautoreverses:YES];        [shake setFromValue:[NSValue valueWithCGPoint:                                 CGPointMake(lockImage.center.x - 5,lockImage.center.y)]];        [shake setTovalue:[NSValue valueWithCGPoint:                               CGPointMake(lockImage.center.x + 5,lockImage.center.y)]];        [lockImage.layer addAnimation:shake forKey:@"position"];    }

正如Jere所说。确保包含导入：

#import <QuartzCore/QuartzCore.h>

您也可以将其添加为UIVIEw中的类别。
