Real-time blur view, like in iOS 7. (deployable on iOS5, 6 and 7)
• • • Make sure you link to the Accelerate.framework • • •
Instantiate it and use it as any other view :)
//Creates a live blur view
UIERealTimeBlurView *blurView = [[UIERealTimeBlurView alloc] initWithFrame:CGRectMake(60, 110, 200, 200)];
[self.view addSubview:blurView];
You can add all the subviews you want to it...
UIImageView *speakerImage = [[UIImageView alloc] initWithFrame:CGRectMake(50, 50, 100, 100)];
speakerImage.image = [UIImage imageNamed:@"speaker"];
[blurView addSubview:speakerImage];
If you want to have a static rendering (useful if your view is presented modally) just set
blurView.renderStatic = YES;
You can set the tint color of the view via the tint property (still TODO: use iOS7 tintColor ;)) - The default one is clearColor
In UIERealTimeBlurView.h you can set the fps by tweaking the global var
extern const CGFloat UIERealTimeBlurViewFPS = 30.f;
If you use this component in your app, please add some credits :) The box blur algorithm is from this beautiful blog post: http://indieambitions.com/idevblogaday/perform-blur-vimage-accelerate-framework-tutorial
