今天写弹出框，做了一个类似于系统UIAlertview弹出的弹出动画效果，代码如下：

+(void)animationWithView:(UIView *)view duration:(CFTimeInterval)duration{

CAKeyframeAnimation * animation;

animation = [CAKeyframeAnimationanimationWithKeyPath:@"transform"];

animation.duration = duration;

animation.removedOnCompletion =NO;

animation.fillMode =kCAFillModeForwards;

NSMutableArray *values = [NSMutableArrayarray];

[values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(0.1,0.1, 1.0)]];

[values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.2,1.2, 1.0)]];

[values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(0.9,0.9, 0.9)]];

[values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.0,1.0, 1.0)]];

animation.values = values;

animation.timingFunction = [CAMediaTimingFunctionfunctionWithName: @"easeInEaseOut"];

[view.layeraddAnimation:animation forKey:nil];

}
