MotionBlur
https://github.com/fastred/MotionBlur
MotionBlur allows you to add motion blur effect to your animations (currently only position's change). See the accompanying blog post 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).你可以看这篇博文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.
