iOS 簡單動畫效果

1、最簡單，最實用，最常用的［移動動畫］

//移動一個view

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

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

// 動畫開始

[UIView beginAnimations:nil context:nil];

// 動畫時間曲線 EaseInOut效果

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 

// 動畫時間

[UIView setAnimationDuration:time];

view.frame = frame;

// 動畫結束（或者用提交也不錯）

[UIView commitAnimations];

}

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

適用範圍：

常常出現在ipad項目中，當使用者點擊一個圖片，或者一條資訊，你將彈出一個詳細頁面［detailview］,將起始frame初始化為cgrectmake(self.view.frame.size.width/2,self.view.size.height/2, 0, 0),結束位置[frame] ,常用的動畫間隔時間0.4f-0.6f。

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

效果，頁面中間將從小到大顯示一個view[detailview]

通常這個View會是放大到全屏，或者半屏大小，然後再點擊後，自動消失。所以這個View會被自義成一個新的View，然後在接收點擊事件後，調用[self removeFromParentView];的方法

2、漸漸顯示一個view,需要在調用此方法的類中重寫此方法

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

/*

 - (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、漸漸隱藏一個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];

}
