1、最简单，最实用，最常用的［移动动画］

//移动一个view

---------------------------------------------------------------------------------------------------------------------------------

+(void)MoveView:(UIView *)view To:(CGRect)frame During:(float)time{

// 动画开始

[UIView beginAnimations:nil context:nil];

// 动画时间曲线 EaseInOut效果

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 

// 动画时间

[UIView setAnimationDuration:time];

view.frame = frame;

// 动画结束（或者用提交也不错）

[UIView commitAnimations];

}

---------------------------------------------------------------------------------------------------------------------------------

适用范围：

常常出现在ipad项目中，当用户点击一个图片，或者一条资讯，你将弹出一个详细页面［detailview］,将起始frame初始化为cgrectmake(self.view.frame.size.width/2,self.view.size.height/2, 0, 0),结束位置[frame] ,常用的动画间隔时间0.4f-0.6f。

[AnimtionTool MoveView:detailview To:frame During:0.5f];

效果，页面中间将从小到大显示一个view[detailview]

通常这个View会是放大到全屏，或者半屏大小，然后再点击后，自动消失。所以这个View会被自义成一个新的View，然后在接收点击事件后，调用[self removeFromParentView];的方法

2、渐渐显示一个view,需要在调用此方法的类中重写此方法

---------------------------------------------------------------------------------------------------------------------------------

/*

 - (void)onAnimationComplete:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {

      if ([animationID isEqualToString: SHOW_VIEW]) {

         //do something

      }  else if ([animationID isEqualToString:HIDDEN_VIEW]) {

         //do something

      }

 }

 */

+(void)ShowView:(UIView *)view To:(CGRect)frame During:(float)time delegate:(id)delegate;{

[UIView beginAnimations:SHOW_VIEW context:nil];

[UIView setAnimationDuration:time];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 

if(delegate !=nil &&[delegate respondsToSelector:@selector(onAnimationComplete:finished:context:)]){

[UIView setAnimationDidStopSelector:@selector(onAnimationComplete:finished:context:)];

[UIView setAnimationDelegate:delegate];

}

view.hidden = NO;

view.layer.opacity = 1.0;

view.frame = frame;

[UIView commitAnimations];

}

---------------------------------------------------------------------------------------------------------------------------------

3、渐渐隐藏一个view

---------------------------------------------------------------------------------------------------------------------------------

+(void)HiddenView:(UIView *)view To:(CGRect)frame During:(float)time delegate:(id)delegate{

[UIView beginAnimations:HIDDEN_VIEW context:nil];

[UIView setAnimationDuration:time];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 

if(delegate !=nil &&[delegate respondsToSelector:@selector(onAnimationComplete:finished:context:)]){

[UIView setAnimationDidStopSelector:@selector(onAnimationComplete:finished:context:)];

[UIView setAnimationDelegate:delegate];

}

view.frame = frame;

view.layer.opacity = 0.0;

[UIView commitAnimations];

}
