IOS開發7-彈出框實現 官方UIAlertView的動畫

頭文件記得導入#import <QuartzCore/QuartzCore.h>，及加入framework

+(void)exChangeOut:(UIView *)changeOutView dur:(CFTimeInterval)dur{

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

    animation.duration = dur;

    //animation.delegate = self;

    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];

}

其中changeOutView 即爲要實現動畫的那個view,dur即爲動畫的時間，調用的時候傳入這2個參數便可；
