大体思路:
在self.view 上放置一个label,label.text从数组中获得,当点击上下页按钮的时候,改变label.text,并且执行翻页效果动画.
效果如图:

_count = _arr.count - 1;
btn.enabled = no;
[self showalert:@"已经是最后一页咯,亲(づ￣ 3￣)づ"];
}
nslog(@"%ld", (long)_count);
}
#pragma catransition动画实现

* @param subtype 动画执行的起始位置,上下左右
* @param view 哪个view执行的动画

- (void) transitionwithtype:(nsstring *) type withsubtype:(nsstring *) subtype forview : (uiview *) view {
catransition *animation = [catransition animation];
animation.duration = 0.7f;
animation.type = type;

animation.subtype = subtype;
}
animation.timingfunction = uiviewanimationoptioncurveeaseinout;
[view.layer addanimation:animation forkey:@"animation"];

主要就是熟悉一下简单动画的实现了
本项目github地址:https://github.com/iosjason/pageblurdemo.git
2 添加启动页和手势控制的翻页效果实现,添加swipe手势后画面切换更生动.

动画效果和上一个是一种效果,具体代码请看我的gibhub,和上一个项目在一个地址里面,这个在 swipegesturepageblurdemo 分支中.
