uiblureffect

问题 I'm working on a map based iOS 11 application and want to make the status bar blurred exactly like it appears in the Apple maps. This is how it looks on the Maps app: Currently, I'm using UIVisualEffectView to replicate this effect. Here's my code: let blurEffect = UIBlurEffect(style: .regular) blurredStatusBar = UIVisualEffectView(effect: blurEffect) blurredStatusBar?.translatesAutoresizingMaskIntoConstraints = false view.addSubview(blurredStatusBar!) However, whatever UIBlurEffect I use, I

问题 I have a column: header with text, body with image, footer with text, all widgets have transparent backgrounds. I want to set the background using a blur of the main image but I keep reaching dead ends. In some situations this would be straight forward but in my scenario the image could be of any size and aspect ratio, and I need the effect to be wrapped with the column. Here are my two failed attempts: Method 1 I have a Stack with the image as the first item, then a BackdropFilter with

问题 I'm using a UIVisualEffectView to blur a section of the screen in SpriteKit like so: let blur:UIBlurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark) let UIEffectView:UIVisualEffectView = UIVisualEffectView(effect: blur) UIEffectView.frame = CGRectMake(0, 0, frame.width, frame.height * 0.15) self.view?.addSubview(UIEffectView) But it appears as a grey shaded area instead of a blur. Strangely, it blurs whilst the GameCenter notification shows at the start, saying "Welcome back, (player)" -

问题 Background Transparency with BLUR Is it possible to blur view without using background Image? I want to show the parent content on top of the background blur view in modal .

问题 I'm using a stock UISplitViewController with out-of-the-box Master and Detail view controllers. In a storyboard, I've added a UIImageView to the Detail controller set to effectively fill the view with a single image. In the Master controller, I've used the following to blur the background of that controller: // In viewDidLoad self.tableView.backgroundColor = [UIColor clearColor]; UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark]; UIVisualEffectView

问题 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

问题 I have a requirements of adding gradient over some portion (only in left and right side ) of UIImageView. I know, this can be done by using CAGradientLayer(). But I am confused with properties locations and colors. Below is my code. It is adding gradient at top and bottom. if let containerView = imageView.superView { let gradient = CAGradientLayer(layer: containerView.layer) gradient.frame = containerView.bounds gradient.colors = [UIColor.clear.cgColor, UIColor.blue.cgColor ,UIColor.blue
