我还在学习UIAnimations,刚进入它,我偶然发现了一个我不确定如何解决的问题.我已经看到了你获得新的高分的游戏,并且它将新的高分增加到旧的高分并且他们使数字动画上下.它看起来非常酷,视觉上很有吸引力.
任何人都可以向我解释这是如何做到的？如果这个问题很容易解决,我很抱歉,就像我说我还在努力学习/完善动画一样.
提前致谢
解决方法
我从
post sergio suggested you look at中获取了代码,但注意到Anshu提到你想要一个上下移动动画而不是一个淡入/淡出动画,所以我改变了代码以适合你想要的.干得好：
// Add transition (must be called after myLabel has been displayed) CATransition *animation = [CATransition animation]; animation.duration = 1.0; //You can change this to any other duration animation.type = kCATransitionMoveIn; //I would assume this is what you want because you want to "animate up or down" animation.subtype = kCATransitionFromTop; //You can change this to kCATransitionFromBottom,kCATransitionFromLeft,or kCATransitionFromRight animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaSEOut]; [myLabel.layer addAnimation:animation forKey:@"changeTextTransition"]; // Change the text myLabel.text = newText;
希望这可以帮助！
