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];

}
