Motivation and Context

Description

Background color for iOS 16 is not changing. This fix solves the issue

This code should be merged to a new branch named swift-3. @efremidze Please create a new branch and I will create the PR again.

This should not be merged in master as of now, since Xcode 8 is still in beta mode.

This commit also makes the pod spec infer the version from the Xcode project thus reducing duplication.

I meddled with the xcodeproj a little to make sure the version is not duplicated around and is set in all the places it should be.

Issue Description

Environment

• iOS Version: [INSERT iOS VERSION HERE]
• Device(s): [INSERT DEVICE(S) HERE]

Hello,

I'm using VisualEffectView to find a custom UIVisualEffectView. When I read ReadMe, iOS 8.0 + is actually crashing when iOS 8.x is run.

private let blurEffect = (NSClassFromString("_UICustomBlurEffect") as! UIBlurEffect.Type).init()

fatal error: unexpectedly found nil while unwrapping an Optional value

it's probably an iOS9+ API

`let effect = VisualEffectView()//VisualEffectView(frame: CGRect(x: 0, y: 0, width: 600, height: 600)) effect.translatesAutoresizingMaskIntoConstraints = false effect.colorTint = .red effect.colorTintAlpha = 0.2 effect.blurRadius = 10 effect.scale = 1

    view.addSubview(effect)
    effect.heightAnchor.constraint(equalTo: view.heightAnchor, multiplier: 0).isActive = true
    effect.widthAnchor.constraint(equalTo: view.widthAnchor, multiplier: 0).isActive = true

`

Motivation and Context

Fixes an issue from #32 Some additional work may be needed to prevent us having to wrap calls to colorTintAlpha with if colorTint != nil conditions but that's another topic.

Description

func _value<T>(forKey key: Key) -> T? now returns an optional.

Hello, I wanted to try out the latest version (4.1.1) with the iOS 14 fix but now I've got some crashes on iOS 13.5.

func newVisualEffectView(tint: UIColor? = nil) -> VisualEffectView {
        let view = VisualEffectView(frame: self.view.frame)
        view.colorTint = tint
        view.colorTintAlpha = 0.92
        view.blurRadius = 7
        view.scale = 1
        return view
}

This raises a runtime error when tint is nil:

func _setValue<T>(_ value: T, forKey key: Key) {
        blurEffect.setValue(value, forKeyPath: key.rawValue)
        if #available(iOS 14, *) {} else {
            self.effect = blurEffect // <- -[NSNull _backgroundColorIgnoringHighContrast]: unrecognized selector sent to instance 0x7fff8062d9d0
        }
}

So I've added a check to not set the colorTintAlpha if there was no tintColor:

func newVisualEffectView(tint: UIColor? = nil) -> VisualEffectView {
        let view = VisualEffectView(frame: self.view.frame)
        view.colorTint = tint
        if view.colorTint != nil {
            view.colorTintAlpha = 0.92
        }
        view.blurRadius = 7
        view.scale = 1
        return view
}

This raises another runtime error when trying to access the tintColor from the new condition:

func _value<T>(forKey key: Key) -> T {
        return blurEffect.value(forKeyPath: key.rawValue) as! T // <- Could not cast value of type 'NSNull' (0x7fff87a92380) to 'UIColor' (0x7fff897eb788).
}

Due to changes in iOS 14 private APIs, I've updated the library to use a workaround discovered by @unboxme. This PR replicates changes from Blurberry and fixes #23. The changes are backwards compatible and the framework API is unchanged.

Description

• Added Swift 5.0 Support

IOS 16 was recently updated, The same code shows the result, which is very different from what it was before iOS 16, Below is the 16 and 16 before the rendering
please help me to solve the problem

Changing colorTint = .clear not solves the problem. It seems like colorTint had effect on _UIVisualEffectSubview, but blue overlay is in _UIVisualEffectBackdropView.

I was expecting that will find a solution here, but now think that only I have this problem.

it is working if you add this

func setValue( value: T, forKey key: Key) { blurEffect.setValue(value, forKeyPath: key.rawValue) if #available(iOS 14, *) { } else { self.effect = blurEffect } }

Is there any way to apply Blur effect on Status Bar view.

Please note that This is not the Bug BUT in iPhone blue effect apply on whole screen area include status bar Real time and battery icon too.

Thanks in Advance.
