iOS 简单动画主要分为三种（这是我的理解）：
第一种：改变位置，大小等
//开始动画 [UIView beginAnimations:nil context:nil]; //设定动画持续时间 [UIView setAnimationDuration:2]; //动画的内容 frame.origin.x += 150; [img setFrame:frame]; //动画结束 [UIView commitAnimations];
第二种：使用UIViewAnimationTransition
[UIView beginAnimations:@"animation" context:nil]; [UIView setAnimationDuration:0.6f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop)]; [UIView setAnimationRepeatAutoreverses:NO]; [self.view addSubview:self.currentView]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view cache:YES]; [UIView commitAnimations];
UIViewAnimationTransition动画主要分为两种，
一种是掀开动画（就像翻日历），分别是 UIViewAnimationTransitionCurlUp ， UIViewAnimationTransitionCurlDown .
另一种是翻转动画（一般地图和列表切换会使用这种），分别是UIViewAnimationTransitionCurlUp, UIViewAnimationTransitionCurlDown .
就是上图的第一排4个按钮展现的动画
第三种：使用CATransition
CATransition *transition = [CATransition animation];
transition.duration = 0.4;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[fromView.layer addAnimation:transition forKey:nil];
CATransition动画分为4种，
1、kCATransitionFade;
2、kCATransitionPush;
3、kCATransitionReveal;
4、kCATransitionMoveIn;
后三种又可以选择4个方向，kCATransitionFromLeft 、kCATransitionFromBottom 、kCATransitionFromRight 、kCATransitionFromTop
就是上图的第2排4个按钮展现的动画
从iOS4.0以后，apple又提供了5个方法：
+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion NS_AVAILABLE_IOS(4_0); + (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion NS_AVAILABLE_IOS(4_0); // delay = 0.0, options = 0 + (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations NS_AVAILABLE_IOS(4_0); // delay = 0.0, options = 0, completion = NULL + (void)transitionWithView:(UIView *)view duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion NS_AVAILABLE_IOS(4_0); + (void)transitionFromView:(UIView *)fromView toView:(UIView *)toView duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options completion:(void (^)(BOOL finished))completion NS_AVAILABLE_IOS(4_0); // toView added to fromView.superview, fromView removed from its superview
例如：改变大小位置
[UIView animateWithDuration:0.6 animations:^{
self.currentView.frame = CGRectMake(30, 30, 200, 300);
}];
或者翻转切换视图
[UIView transitionFromView:self.mapviewContainer toView:self.listContainer duration:0.75 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished){
}];
下面8个是私有api，如果应用要上appstore，请勿使用。
就是上图的下面8个按钮展现的动画
