我没有用GPUImge  使用了  FXBlurView which works
great on iOS5+

只有两个文件

https://github.com/nicklockwood/FXBlurView

CocoaPods:

-> FXBlurView (1.3.1)

   UIView subclass that replicates the iOS 7 realtime background blur effect, but works on iOS 5 and above.

   pod ‘FXBlurView‘, ‘~> 1.3.1‘

   - Homepage: http://github.com/nicklockwood/FXBlurView

   - Source:   https://github.com/nicklockwood/FXBlurView.git

   - Versions: 1.3.1, 1.3, 1.2, 1.1, 1.0 [master repo]

I added it by using:

FXBlurView *blurView = [[FXBlurView alloc] initWithFrame:CGRectMake(50, 50, 150, 150)];

[self.blurView setDynamic:YES];

[self.view addSubview:self.blurView];
