翻页效果

引入 #import <QuartzCore/QuartzCore.h>

公有方法实现

[UIView beginAnimations:@"animationID" context:nil];

[UIView setAnimationDuration:1.0f];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

[UIView setAnimationRepeatAutoreverses:NO];

[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:subview2 cache:YES];

//最后启动动画

[UIView commitAnimations];

以下是私有方法实现

// CATransition *transition = [CATransition animation];

// transition.duration = 1.0f;

// transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

// transition.type = @"pageUnCurl";

// transition.subtype = kCATransitionFromRight;

// transition.delegate = subview2.layer;

// [subview2.layer addAnimation:transition forKey:nil];

函数讲解

//首先设置动画的相关参数

[UIView beginAnimations:@"Curl"context:nil];
[UIView setAnimationDuration:1.25];//时间
[UIViewsetAnimationCurve:UIViewAnimationCurveEaseInOut];//速度

//然后设置动画的动作和目标视图
[UIViewsetAnimationTransition:UIViewAnimationTransitionCurlUpforView:self.viewcache:YES];

参数UIViewAnimationTransitionCurlUp代表向上翻页，如果向下的话UIViewAnimationTransitionCurlDown.
forView那把当前的视图传进去。
