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]
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];
}
