#pragma mark 弹出view

-(void)exChangeOut:(UIView *)changeOutView dur:(CFTimeInterval)dur

{

    CAKeyframeAnimation * animation;

    animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"];

    animation.duration = dur;

    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"];

    [changeOutView.layer addAnimation:animation forKey:nil];

}

使用：

[self exChangeOut:myview dur:0.5];
