UIView动画相关

UIViewAnimationOptions的枚举类型

typedef enum UIViewAnimationOptions : NSUInteger {
    UIViewAnimationOptionLayoutSubviews = 1 <<  0,　　　　　　　　 //在动画的持续时间里，子视图跟随父视图运动
    UIViewAnimationOptionAllowUserInteraction = 1 <<  1,　　　　　//在动画的开始后，允许用户交互

    UIViewAnimationOptionBeginFromCurrentState = 1 <<  2,　　　　 //所有视图从当前状态开始运行。
    UIViewAnimationOptionRepeat = 1 <<  3,　　　　　　　　　　　　　 //重复执行动画
    UIViewAnimationOptionAutoreverse = 1 <<  4,　　　　　　　　　　 //动画运行到结束点后仍然以动画方式回到初始点。需设置重复执行动画
    UIViewAnimationOptionOverrideInheritedDuration = 1 <<  5,　  //忽略嵌套动画时间设置。
    UIViewAnimationOptionOverrideInheritedCurve = 1 <<  6,　　　　//忽略嵌套动画速度设置。
    UIViewAnimationOptionAllowAnimatedContent = 1 <<  7,　　　　　//动画过程中重绘视图（注意仅仅适用于转场动画）。

    UIViewAnimationOptionShowHideTransitionViews = 1 <<  8,　　　//视图切换时直接隐藏旧视图，而不是将旧视图从父视图移除（仅适用于转场动画）
    UIViewAnimationOptionOverrideInheritedOptions = 1 <<  9,　　 //不继承父动画设置或动画类型。

//设置动画速度

    UIViewAnimationOptionCurveEaseInOut = 0 << 16,　　　　　　　　　//由慢到快
    UIViewAnimationOptionCurveEaseIn = 1 << 16,　　　　　　　　　　　//由慢到特别快
    UIViewAnimationOptionCurveEaseOut = 2 << 16,　　　　　　　　　　//由快到慢
    UIViewAnimationOptionCurveLinear = 3 << 16,　　　　　　　　　　　//匀速

//转场动画相关
    UIViewAnimationOptionTransitionNone = 0 << 20,　　　　　　　　　//无转场动画
    UIViewAnimationOptionTransitionFlipFromLeft = 1 << 20,　　　　//转场从左翻转
    UIViewAnimationOptionTransitionFlipFromRight = 2 << 20,　　　　//转场从右翻转
    UIViewAnimationOptionTransitionCurlUp = 3 << 20,　　　　　　　　//上卷转场
    UIViewAnimationOptionTransitionCurlDown = 4 << 20,　　　　　　　//下卷转场
    UIViewAnimationOptionTransitionCrossDissolve = 5 << 20,　　　　//转场交叉消失
    UIViewAnimationOptionTransitionFlipFromTop = 6 << 20,　　　　　//转场从上翻转
    UIViewAnimationOptionTransitionFlipFromBottom = 7 << 20,　　　//转场从下翻转

//动画帧
    UIViewAnimationOptionPreferredFramesPerSecondDefault = 0 << 24,　　　//默认的帧每秒.
    UIViewAnimationOptionPreferredFramesPerSecond60 = 3 << 24,　　　　　　//60帧每秒的帧速率.
    UIViewAnimationOptionPreferredFramesPerSecond30 = 7 << 24　　　　　　//30帧每秒的帧速率.
} UIViewAnimationOptions;

简单动画 animateWithDuration

一般用来做view的frame改变使动画流畅

+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOLfinished))completion

+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations 

[UIView animateWithDuration:0.4 animations:^{  
         self.animateview.center = CGPointMake(self.view.center.x + 10, self.view.center.y + 10);  
     } completion:^(BOOL finished) {  
         [UIView animateWithDuration:0.2 animations:^{  
             self.animateview.center = self.view.center;  
         } completion:^(BOOL finished) {  
               
         }];  
     }]; 

animateWithDuration:delay:options:

这里的option参数主要是用来指动画view移动的快慢 

比如：UIViewAnimationOptionCurveLinear 是线性运动  而UIViewAnimationOptionCurveEaseIn 由到快

可以写在一起比较一下

[UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{  
      self.animateview.center = CGPointMake(self.animateview.center.x, self.view.center.y);  
  } completion:^(BOOL finished) {  
        
  }];  
  [UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionCurveEaseInOut animations:^{  
      self.xx.center = self.view.center;  
  } completion:^(BOOL finished) {  
        
  }];  

transitionWithView

一般用来做view显示隐藏效果  option是切换的效果 

[UIView transitionWithView:self.animateview duration:0.9 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{  
       self.animateview.hidden = YES;  
   } completion:^(BOOL finished) {  
         
   }];  
   [UIView transitionWithView:self.xx duration:0.9 options:UIViewAnimationOptionTransitionFlipFromTop animations:^{  
       self.xx.hidden = YES;  
   } completion:^(BOOL finished) {  
         
   }];  

transitionFromView

用于2个view之间的切换从fromView切换到toview

[UIView transitionFromView:self.topView toView:self.bottomView duration:0.3 options:UIViewAnimationOptionTransitionCrossDissolve completion:^(BOOL finished) {  
     NSInteger topIndex = [self.view.subviews indexOfObject:self.topView];  
     NSInteger bottomIndex = [self.view.subviews indexOfObject:self.bottomView];  
     [self.view exchangeSubviewAtIndex:topIndex withSubviewAtIndex:bottomIndex];  
 }];  

usingSpringWithDamping: initialSpringVelocity:

damping指的是阻尼系数 这个系统在0，1之间 系数越大弹性越小

initialSpringVelocity 初始弹动速度 速度越快 停下的时候越缓慢因为时间已经定死了 自行对比几组感觉一下

[UIView animateWithDuration:0.25 delay:0 usingSpringWithDamping:0.1 initialSpringVelocity:15 options:UIViewAnimationOptionCurveEaseOut animations:^{  
      self.animateview.center = self.view.center;  
  } completion:^(BOOL finished) {  
        
  }];  

animateKeyframesWithDuration

来自iOS7 Day-by-Day :: Day 11 :: UIView Key-frame Animations

void(^animationBlock)() = ^{  
       NSArray *rainbowColors = @[[UIColor orangeColor],  
                                  [UIColor yellowColor],  
                                  [UIColor greenColor],

                                  [UIColor purpleColor],  
                                  [UIColor redColor]];  
         
       NSUInteger colorCount = [rainbowColors count];  
       for(NSUInteger i=0; i<colorCount; i++) {  
           [UIView addKeyframeWithRelativeStartTime:i/(CGFloat)colorCount  
                                   relativeDuration:1/(CGFloat)colorCount  
                                         animations:^{  
                                             self.xx.backgroundColor = rainbowColors[i];  
                                         }];  
   }  
   };  
       [UIView animateKeyframesWithDuration:1 delay:0 options:UIViewKeyframeAnimationOptionCalculationModePaced animations:animationBlock completion:nil];
