iOS開發總結（A0）- UIView Animation

標籤：

運用uiview的幾個animation方面可以使動畫變的更加簡單

1. 如果是view properties 的變化，使用以下方法

+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion; + (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion; + (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations;+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay usingSpringWithDamping:(CGFloat)dampingRatio initialSpringVelocity:(CGFloat)velocity options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion;

可以用作animation的properties有：frame，bounds，center，alpha, transform(setTransform),bkgcolor

如果options中有repeat 選項，那麼該如何停止動畫呢？

可用[self.layer removeAllAnimations];停止動畫

更多控制，設定 CAMediaTiming中properties（可參考http://www.cnblogs.com/gaoxiao228/archive/2013/01/28/2880285.html）

 

2. 如果是view 的hierachy 變化，使用以下方法：

+ (void)transitionWithView:(UIView *)view duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion ;+ (void)transitionFromView:(UIView *)fromView toView:(UIView *)toView duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options completion:(void (^)(BOOL finished))completion; // toView added to fromView.superview, fromView removed from its superview
