今天总结一下UIView动画就是 UiView动画是基于高层API封装进行封装的,对UIView的属性进行修改时候所产生的动画.
基本动画下面两种方法是最常用的两种.
+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations
animations 修改View属性的Block 下面是支持修改的属性
@property frame@property bounds@property center@property transform@property alpha@property backgroundColor@property contentStretch
+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
completion 动画完成blockBOOL finished 表示动画是否完成
继续+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
delay 延迟执行时间options 动画效果枚举 ,下面是全部枚举的说明
动画效果相关UIViewAnimationOptionLayoutSubviews //提交动画的时候布局子控件，表示子控件将和父控件一同动画。UIViewAnimationOptionAllowUserInteraction //动画时允许用户交流，比如触摸UIViewAnimationOptionBeginFromCurrentState //从当前状态开始动画UIViewAnimationOptionRepeat //动画无限重复UIViewAnimationOptionAutoreverse //执行动画回路,前提是设置动画无限重复UIViewAnimationOptionOverrideInheritedDuration //忽略外层动画嵌套的执行时间UIViewAnimationOptionOverrideInheritedCurve //忽略外层动画嵌套的时间变化曲线UIViewAnimationOptionAllowAnimatedContent //通过改变属性和重绘实现动画效果，如果key没有提交动画将使用快照UIViewAnimationOptionShowHideTransitionViews //用显隐的方式替代添加移除图层的动画效果UIViewAnimationOptionOverrideInheritedOptions //忽略嵌套继承的选项时间函数曲线相关
UIViewAnimationOptionCurveEaseInOut //时间曲线函数，由慢到快UIViewAnimationOptionCurveEaseIn //时间曲线函数，由慢到特别快UIViewAnimationOptionCurveEaseOut //时间曲线函数，由快到慢UIViewAnimationOptionCurveLinear //时间曲线函数，匀速转场动画相关的
UIViewAnimationOptionTransitionNone //无转场动画UIViewAnimationOptionTransitionFlipFromLeft //转场从左翻转UIViewAnimationOptionTransitionFlipFromRight //转场从右翻转UIViewAnimationOptionTransitionCurlUp //上卷转场UIViewAnimationOptionTransitionCurlDown //下卷转场UIViewAnimationOptionTransitionCrossDissolve //转场交叉消失UIViewAnimationOptionTransitionFlipFromTop //转场从上翻转UIViewAnimationOptionTransitionFlipFromBottom //转场从下翻转弹簧动画
+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay usingSpringWithDamping:(CGFloat)dampingRatio initialSpringVelocity:(CGFloat)velocity options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
dampingRatio 弹簧的阻尼 如果为1动画则平稳减速动画没有振荡。 这里值为 0~1velocity 弹簧的速率。数值越小，动力越小，弹簧的拉伸幅度就越小。反之相反。比如：总共的动画运行距离是200 pt，你希望每秒 100pt 时，值为 0.5；
例子[UIView animateWithDuration:2 delay:2 usingSpringWithDamping:.5 initialSpringVelocity:.5 options:UIViewAnimationOptionRepeat animations:^{ view.center = self.view.center;} completion:^(BOOL finished) { }]; 
过渡动画 + (void)transitionWithView:(UIView *)view duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^ __nullable)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
view 参与转换的视图
例子UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];[self.view addSubview:view];view.center = self.view.center;view.backgroundColor = [UIColor redColor];UIView *view_1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];view_1.backgroundColor = [UIColor yellowColor];[UIView transitionWithView:view duration:3 options:UIViewAnimationOptionTransitionCurlUp animations:^{ [view addSubview:view_1]; } completion:^(BOOL finished) { }]; 
继续 + (void)transitionFromView:(UIView *)fromView toView:(UIView *)toView duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options completion:(void (^ __nullable)(BOOL finished))completion
fromView 一开始的视图toView 转换后的视图
例子UIView *baseView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];[self.view addSubview:baseView];baseView.center = self.view.center;UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];[baseView addSubview:view];view.backgroundColor = [UIColor redColor];UIView *view_1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];view_1.backgroundColor = [UIColor yellowColor];[UIView transitionFromView:view toView:view_1 duration:2 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) { }]; 
关键帧动画 + (void)animateKeyframesWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewKeyframeAnimationOptions)options animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion+ (void)addKeyframeWithRelativeStartTime:(double)frameStartTime relativeDuration:(double)frameDuration animations:(void (^)(void))animations
duration 总持续时间UIViewKeyframeAnimationOptions options 枚举 下面说明frameStartTime 相对开始时间frameDuration 相对持续时间
例子UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 50, 50)];view.backgroundColor = [UIColor orangeColor];[self.view addSubview:view];[UIView animateKeyframesWithDuration:3 delay:3 options:UIViewKeyframeAnimationOptionRepeat animations:^{ [UIView addKeyframeWithRelativeStartTime:0 relativeDuration:.3 animations:^{ view.frame = CGRectMake(20, 100, 100, 100); }]; [UIView addKeyframeWithRelativeStartTime:.3 relativeDuration:.6 animations:^{ view.frame = CGRectMake(60, 100, 80, 80); }]; [UIView addKeyframeWithRelativeStartTime:.6 relativeDuration:1 animations:^{ view.frame = CGRectMake(20, 20, 50, 50); }];} completion:^(BOOL finished) {}]; 
UIViewKeyframeAnimationOptions
UIViewKeyframeAnimationOptionLayoutSubviews //提交动画的时候布局子控件，表示子控件将和父控件一同动画。 UIViewKeyframeAnimationOptionAllowUserInteraction //动画时允许用户交流，比如触摸 UIViewKeyframeAnimationOptionBeginFromCurrentState //从当前状态开始动画 UIViewKeyframeAnimationOptionRepeat //动画无限重复 UIViewKeyframeAnimationOptionAutoreverse //执行动画回路,前提是设置动画无限重复 UIViewKeyframeAnimationOptionOverrideInheritedDuration //忽略外层动画嵌套的执行时间 UIViewKeyframeAnimationOptionOverrideInheritedOptions //忽略嵌套继承的选项关键帧动画独有 UIViewKeyframeAnimationOptionCalculationModeLinear //选择使用一个简单的线性插值计算的时候关键帧之间的值。 UIViewKeyframeAnimationOptionCalculationModeDiscrete //选择不插入关键帧之间的值,而是直接跳到每个新的关键帧的值。 UIViewKeyframeAnimationOptionCalculationModePaced //选择计算中间帧数值算法使用一个简单的节奏。这个选项的结果在一个均匀的动画。 UIViewKeyframeAnimationOptionCalculationModeCubic //选择计算中间帧使用默认卡特莫尔罗花键,通过关键帧的值。你不能调整该算法的参数。 这个动画好像会更圆滑一些.. UIViewKeyframeAnimationOptionCalculationModeCubicPaced //选择计算中间帧使用立方计划而忽略的时间属性动画。相反,时间参数计算隐式地给动画一个恒定的速度。剩下两个操作
+ (void)performSystemAnimation:(UISystemAnimation)animation onViews:(NSArray<UIView *> *)views options:(UIViewAnimationOptions)options animations:(void (^ __nullable)(void))parallelAnimations completion:(void (^ __nullable)(BOOL finished))completion+ (void)performWithoutAnimation:(void (NS_NOESCAPE ^)(void))actionsWithoutAnimation
1.删除视图上的子视图 animation这个枚举只有一个删除值...views操作的view 这会让那个视图变模糊、收缩和褪色, 之后再给它发送 removeFromSuperview 方法。2.在动画block中不执行动画的代码.
例子 UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 50, 50)]; view.backgroundColor = [UIColor orangeColor]; UIView *view_1 = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 20, 20)]; [view addSubview:view_1]; view_1.backgroundColor = [UIColor redColor]; [self.view addSubview:view]; [UIView animateKeyframesWithDuration:3 delay:3 options:UIViewKeyframeAnimationOptionRepeat|UIViewKeyframeAnimationOptionAutoreverse animations:^{ view.frame = CGRectMake(100, 100, 50, 50); [UIView performWithoutAnimation:^{ view.backgroundColor = [UIColor blueColor]; }]; } completion:^(BOOL finished) { }]; [UIView performSystemAnimation:UISystemAnimationDelete onViews:@[view_1] options:0 animations:^{ view_1.alpha = 0; } completion:^(BOOL finished) { }]; 
结束 就先写到这里吧 如果有用的话请点个喜欢..
