UIAlertView的动画效果实现代码

UIAlertView的动画效果实现代码

首先要加入QuartzCore.framework

#import "QuartzCore/QuartzCore.h"

- (void)test
{
CAKeyframeAnimation * animation;
animation = [CAKeyframeAnimation
animationWithKeyPath:@"transform"];
animation.duration = 0.5;
animation.delegate = self;
animation.removedOnCompletion =
YES;
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"];
[tempView.layer addAnimation:animation forKey:nil];
}
