需要引入 QuartzCore

+(void)animationWithView:(UIView *)view duration:(CFTimeInterval)duration{    CAKeyframeAnimation * animation;    animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"];    animation.duration = duration;    animation.removedOnCompletion = NO;    animation.fillMode = kCAFillModeForwards;    NSMutableArray *values = [NSMutableArray array];    [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(0.1, 0.1, 1.0)]];    [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.2, 1.2, 1.0)]];    [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(0.9, 0.9, 0.9)]];    [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.0, 1.0, 1.0)]];    animation.values = values;    animation.timingFunction = [CAMediaTimingFunction functionWithName: @"easeInEaseOut"];    [view.layer addAnimation:animation forKey:nil];}
