小胖说事5------CATransition的用法

CATransition的type属性 

 1.#define定义的常量
     kCATransitionFade   交叉淡化过渡
     kCATransitionMoveIn 新视图移到旧视图上面
     kCATransitionPush   新视图把旧视图推出去
     kCATransitionReveal 将旧视图移开,显示下面的新视图 

 2.用字符串表示
     pageCurl            向上翻一页
     pageUnCurl          向下翻一页
     rippleEffect        滴水效果
     suckEffect          收缩效果，如一块布被抽走
     cube                立方体效果
     oglFlip             上下翻转效果  

- (void)MyCAnimation1 {   

    CATransition *animation = [CATransition animation];
    //动画时间
    animation.duration = 1.0f;
    //display mode, slow at beginning and end
    animation.timingFunction = UIViewAnimationCurveEaseInOut;
    //过渡效果
    animation.type = kCATransitionMoveIn;
    //过渡方向
    animation.subtype = kCATransitionFromTop;
    //添加动画
    [imageView.layer addAnimation:animation forKey:nil];
}  

- (void)MyCAnimation2 {   

    CATransition *animation = [CATransition animation];
    //动画时间
    animation.duration = 1.0f;
    //display mode, slow at beginning and end
    animation.timingFunction = UIViewAnimationCurveEaseInOut;
    //在动画执行完时是否被移除
    animation.removedOnCompletion = NO;
    //过渡效果
    animation.type = @"pageCurl";
    //过渡方向
    animation.subtype = kCATransitionFromRight;
    //暂时不知,感觉与Progress一起用的,如果不加,Progress好像没有效果
    animation.fillMode = kCAFillModeForwards;
    //动画停止(在整体动画的百分比).
    animation.endProgress = 0.7;
    [imageView.layer addAnimation:animation forKey:nil];
}  

- (void)MyCAnimation3 {   

    CATransition *animation = [CATransition animation];
    //动画时间
    animation.duration = 1.0f;
    //display mode, slow at beginning and end
    animation.timingFunction = UIViewAnimationCurveEaseInOut;
    //过渡效果
    animation.type = @"pageUnCurl";
    //过渡方向
    animation.subtype = kCATransitionFromRight;
    //暂时不知,感觉与Progress一起用的,如果不加,Progress好像没有效果
    animation.fillMode = kCAFillModeBackwards;
    //动画开始(在整体动画的百分比).
    animation.startProgress = 0.3;
    [imageView.layer addAnimation:animation forKey:nil];
}
