首先,一直以为摇一摇的功能实现好高大上,结果百度了。我自己也模仿写了一个demo。主要代码如下:
新建一个项目,名字为AnimationShake。
主要代码:
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (motion == UIEventSubtypeMotionShake )
{
// User was shaking the device. Post a notification named "shake".
[[NSNotificationCenter defaultCenter] postNotificationName:@"shake" object:self];
}
}
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
}
-(void)addAnimations{
AudioServicesPlaySystemSound(_soundID);
//让imgup上下移动
CABasicAnimation *translation2 = [CABasicAnimation animationWithKeyPath:@"position"];
translation2.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
translation2.fromValue = [NSValue valueWithCGPoint:CGPointMake(160, 115)];
translation2.toValue = [NSValue valueWithCGPoint:CGPointMake(160, 40)];
translation2.duration = 0.4;
translation2.repeatCount = 1;
translation2.autoreverses = YES;
//让imagdown上下移动
CABasicAnimation *translation = [CABasicAnimation animationWithKeyPath:@"position"];
translation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
translation.fromValue = [NSValue valueWithCGPoint:CGPointMake(160, 345+44+20)];
translation.toValue = [NSValue valueWithCGPoint:CGPointMake(160, 420)];
translation.duration = 0.4;
translation.repeatCount = 1;
translation.autoreverses = YES;
[_imgDown.layer addAnimation:translation forKey:@"translation"];
[_imgUp.layer addAnimation:translation2 forKey:@"translation2"];
}
