基于PhoneGap 2.0.0 源码，修改 Commands 包下的 CDVSplashScreen 类，使用 Splashscreen的过度效果更自然[渐变透明|左右上下Slide|翻页]，以下代码只是抛砖引玉，可以利用ios的动画库实现更多的过度动画。 希望本文能帮助一些孩童学习PHONEGAP的用法，更灵活运用源码满足自己的开发需求。

- (void) __show:(BOOL)show 
{ 
    // Legacy support - once deprecated classes removed, clean this up 
    id<UIApplicationDelegate> delegate = [[UIApplication sharedApplication] delegate]; 
     
    if ([delegate respondsToSelector:@selector(viewController)]) { 
        id vc = [delegate performSelector:@selector(viewController)]; 
        if ([vc isKindOfClass:[CDVViewController class]]) {

            [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:((CDVViewController*)vc).view cache:YES]; 
            [UIView setAnimationDelegate:((CDVViewController*)vc)]; 
　　　　　　　// 动画结束后执行隐藏操作 
            [UIView setAnimationDidStopSelector:@selector(showAnimationDone:vc:show:finished:context:)];

            ((CDVViewController*)vc).activityView.alpha = 0.0; //让Splashscreen 的活动视图的透明度渐渐变为0; 
            [UIView commitAnimations]; 
        } 
    } 
} 
 
//动画结束后隐藏Splashscreen
