利用iOS开发实现翻转扑克牌动画的方法
前言
本文主要给大家介绍的关于利用iOS开发实现翻转扑克牌动画的方法,分享出来供大家参考学习,下面话不多说,来一起看看详细的介绍吧。
动画效果
实现原理
实现原理就是创建三个扑克牌pockerView , 先在扑克牌上添加一个imageview,作为牌的背面。然后实现翻转动画,在翻转的时候将imageview移除,添加另一个imageview作为正面。
核心代码:
方法一: 翻转动画,内部实现还是方法二
+ (void)transitionWithView:(UIView *)view duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^ __nullable)(void))animations completion:(void (^ __nullable)(BOOL finished))completion NS_AVAILABLE_IOS(4_0);
方法二 :UIView动画
[UIView beginAnimations:@"aa" context:nil]; [UIView setAnimationDuration:_duration]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [view.imgview1 removeFromSuperview]; [view addSubview:view.imgview2]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:view cache:NO]; [UIView commitAnimations];
