iOS動畫彙總

iOS 簡單動畫主要分爲三種（這是我的理解）：

第一種：改變位置，大小等

//開始動畫
[UIView beginAnimations:nil context:nil];
//設定動畫持續時間
[UIView setAnimationDuration:2];
//動畫的內容
frame.origin.x += 150;
[img setFrame:frame];
//動畫結束
[UIView commitAnimations];

第二種：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動畫主要分爲兩種，

一種是掀開動畫（就像翻日曆），分別是 UIViewAnimationTransitionCurlUp ， UIViewAnimationTransitionCurlDown .

另一種是翻轉動畫（一般地圖和列表切換會使用這種），分別是UIViewAnimationTransitionCurlUp,    UIViewAnimationTransitionCurlDown .

就是上圖的第一排4個按鈕展現的動畫

第三種：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動畫分爲4種，

1、kCATransitionFade;

2、kCATransitionPush;

3、kCATransitionReveal;

4、kCATransitionMoveIn;

後三種又可以選擇4個方向，kCATransitionFromLeft 、kCATransitionFromBottom 、kCATransitionFromRight 、kCATransitionFromTop

就是上圖的第2排4個按鈕展現的動畫

從iOS4.0以後，apple又提供了5個方法：

+ (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：改變大小位置

[UIView animateWithDuration:0.6 animations:^{
        self.currentView.frame = CGRectMake(30, 30, 200, 300);
    }];

或者翻轉切換視圖

[UIView transitionFromView:self.mapviewContainer toView:self.listContainer duration:0.75 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished){

    }];

下面8個是私有api，如果應用要上appstore，請勿使用。
就是上圖的下面8個按鈕展現的動畫
