ios 学习总结之动画（转）

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
