MotionBlur

 

MotionBlur allows you to add motion blur effect to your animations (currently only position's change). See the  to learn how it's implemented.

MotionBlur允许你添加动态模糊特效(目前只支持位移变化).你可以看这篇来看看是怎么实现的.

 

Note how the text and icons on the menu get blurred when it slides in and out.

注意看,这个文字以及图片会在滑入或者滑出的时候变得模糊了.

 

Usage

First, import it with:

首先,导入头文件:

#import "UIView+MotionBlur.h"

then use it with:

然后这么用:

[yourView enableBlurWithAngle:M_PI_2 completion:^{    [UIView animateWithDuration:0.5                          delay:0 usingSpringWithDamping:0.8 initialSpringVelocity:0.3 options:UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionBeginFromCurrentState animations:^{ CGRect f = yourView.frame; f.origin = CGPointMake(0, 300); yourView.frame = f; } completion:^(BOOL finished) { [yourView disableBlur]; }]; }];

Snapshot and blur are computed before the animation, that's why the API is asynchronous. You should also see the example project and read comments in the header file:Classes/UIView+MotionBlur.h.

截图以及模糊会在动画执行前就计算好了.所以,这是这个API为什么是异步的.你可以查看头文件来了解详情.
