How do you use Visual Effect Views with Blur and Vibrancy in Interface Builder? I've dragged this item out into the View, then dragged a UILabel onto the last view in the hierarchy - the vibrant effect's contentView I assume. This results in a blurred view overtop but there is no label visible. Anywhere else I place the label in the hierarchy it does become visible but it's just solid black text. Finally figured it out. In a UIViewController change the view's background to blue Drag a Visual Effect Views with Blur and Vibrancy object into the view, so it's added as a subview In the first

So I'm using the new UIViewPropertyAnimator and UIVisualEffectView to achieve the same thing as the Spotlight search when you scrolling down on the home screen and it blurs the background. I'm using the fractionComplete property to set the procent of how much to blur when panning a UIView. animator = UIViewPropertyAnimator(duration: 1, curve: .linear) { self.blurEffectView.effect = nil } And the amount of blurriness is changed with a value between 0.0 - 1.0. animator?.fractionComplete = blurValue But when I cancel the pan gesture I want the blur to animate back from where it is to no blur (e.g

My app utilizes UIVisualEffectView to blur the background just like Control Center. But I discovered the iPad 2 (and Retina iPad) which can run iOS 8 isn't powerful enough to display that effect so it reverts to a gray color. I would like to be able to detect if the device the app is running on is powerful enough to display the blur effect, and if not I won't apply it, instead I'll change the background color to something that looks much better than that gray color. But I don't want to just check if the device is an iPad 2 or iPad 3rd gen (does it affect 4th as well?). Is there a better way to

I have some visual effect views with blur and vibrancy in one of my view controllers. I have labels working correctly with vibrancy, but every time i try to add a UIButton to the view, the text appears to be transparent, and the background of the button appears to have vibrancy. I am looking for the effect the "Edit" button has in notification center. I have attached some photos for reference. What I want: What is happening: If there is no way to accomplish this in IB, can it be done with code? I am using Swift. EDIT Now here is what happening, it appears with vibrancy, but the text is not

Title pretty much asks it all... I'm playing with the iOS8 Visual Effect View with Blur . It's over a UIImageView that shows a user choosable background photo. The view placed in the contentView itself is my own custom view, shows a sort of graph/calendar. Most of said calendar graph is transparent. The blur it applies to the photo behind it is really heavy. I'd like to let more of the detail leak through. But Apple only seems to give three canned values: typedef enum { UIBlurEffectStyleExtraLight, UIBlurEffectStyleLight, UIBlurEffectStyleDark } UIBlurEffectStyle; I've monkied around with

I am presenting a UIViewController that contains a UIVisualEffectView as follows: -(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath { [self performSegueWithIdentifier:@"segueBlur" sender:nil]; } -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if([segue.identifier isEqualToString:@"segueBlur"]) { ((UIViewController *)segue.destinationViewController).providesPresentationContextTransitionStyle = YES; ((UIViewController *)segue.destinationViewController).definesPresentationContext = YES; ((UIViewController *)segue
