在我的xcode项目中,我有一个UIImage。我想让它从左到右摇动(动画)一点点。我写了这段代码,然而,它没有用。
-(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,我怎么能让我的形象动摇?

这是我用于该效果的代码。
-(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"];
}
提到Jere
。确保包含导入:
#import <QuartzCore/QuartzCore.h>
您也可以在UIView
上将其添加为类别。

brynbodayles的回答也适用于iOS8下的swift动画。
导入QuartzCore:
func shakeView(){
var shake:CABasicAnimation = CABasicAnimation(keyPath: "position")
shake.duration = 0.1
shake.repeatCount = 2
shake.autoreverses = true
var from_point:CGPoint = CGPointMake(LoginField.center.x - 5, LoginField.center.y)
var from_value:NSValue = NSValue(CGPoint: from_point)
var to_point:CGPoint = CGPointMake(LoginField.center.x + 5, LoginField.center.y)
var to_value:NSValue = NSValue(CGPoint: to_point)
shake.fromValue = from_value
shake.toValue = to_value
LoginField.layer.addAnimation(shake, forKey: "position")
}
答案 2 :(得分:0)
func shakeView(_ view: UIView?) {
let shake = CABasicAnimation(keyPath: "position")
shake.duration = 0.1
shake.repeatCount = 2
shake.autoreverses = true
shake.fromValue = NSValue(cgPoint: CGPoint(x: (view?.center.x)! - 5, y: view?.center.y ?? 0.0))
shake.toValue = NSValue(cgPoint: CGPoint(x: (view?.center.x)! + 5, y: view?.center.y ?? 0.0))
view?.layer.add(shake, forKey: "position")
}

来自Corona回答
在多个按钮和SWIFT3视图中提供摇动动画
视图动画只需将扩展名UIButton更改为扩展名UIView
extension UIButton
{
func shakeAnim ()
{
let shake:CABasicAnimation = CABasicAnimation(keyPath: "position")
shake.duration = 0.1
shake.repeatCount = 2
shake.autoreverses = true
let from_point:CGPoint = CGPoint(x:self.center.x - 5,y: self.center.y)
let from_value:NSValue = NSValue(cgPoint: from_point)
let to_point:CGPoint = CGPoint(x:self.center.x + 5,y: self.center.y)
let to_value:NSValue = NSValue(cgPoint: to_point)
shake.fromValue = from_value
shake.toValue = to_value
self.layer.add(shake, forKey: "position")
}
}
