UIView的，翻转、旋转，偏移，翻页，缩放，取反的动画效果

 

翻转的动画

//开始动画

    [UIView beginAnimations:@"doflip" context:nil];

//设置时常

    [UIView setAnimationDuration:1];

//设置动画淡入淡出

    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

//设置代理

    [UIView setAnimationDelegate:self];

//设置翻转方向

    [UIView setAnimationTransition:

   UIViewAnimationTransitionFlipFromLeft  forView:manImageView cache:YES];

//动画结束

    [UIView commitAnimations];

旋转动画

 

创建一个CGAffineTransform  transform对象

    CGAffineTransform  transform; 

//设置旋转度数

    transform = CGAffineTransformRotate(manImageView.transform,M_PI/6.0);

//动画开始

    [UIView beginAnimations:@"rotate" context:nil ];

//动画时常

    [UIView setAnimationDuration:2];

//添加代理

    [UIView setAnimationDelegate:self];

//获取transform的值

    [manImageView setTransform:transform];

//关闭动画

    [UIView commitAnimations]; 

偏移动画

[UIView beginAnimations:@"move" context:nil];

    [UIView setAnimationDuration:2];

    [UIView setAnimationDelegate:self]；

//改变它的frame的x,y的值

    manImageView.frame=CGRectMake(100,100, 120,100);

    [UIView commitAnimations];

翻页动画

 [UIView beginAnimations:@"curlUp" context:nil];

    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];//指定动画曲线类型，该枚举是默认的，线性的是匀速的

    //设置动画时常

    [UIView setAnimationDuration:1];

     [UIView setAnimationDelegate:self];

    //设置翻页的方向

    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:manImageView cache:YES];

    //关闭动画

    [UIView commitAnimations];

缩放动画

CGAffineTransform  transform;

    transform = CGAffineTransformScale(manImageView.transform,1.2,1.2);

    [UIView beginAnimations:@"scale" context:nil];

    [UIView setAnimationDuration:2];

    [UIView setAnimationDelegate:self];

    [manImageView setTransform:transform];

    [UIView commitAnimations];

取反的动画效果是根据当前的动画取他的相反的动画

 

CGAffineTransform transform;

    transform=CGAffineTransformInvert(manImageView.transform);

    

    [UIView beginAnimations:@"Invert" context:nil];

    [UIView setAnimationDuration:2];//动画时常

    [UIView setAnimationDelegate:self];

    [manImageView setTransform:transform];//获取改变后的view的transform

    [UIView commitAnimations];//关闭动画
