Replace the volume popup with a more subtle way to display the volume when the user changes it with the volume rocker.
# Why and how
The iOS default popover showing the volume status that appears when the user clicks the volume rocker is a big obtrusive glossy view that covers the content shown. This library offers a way to show a more subtle indicator.
To make sure that the popover is not shown there are two conditions that need to be satisfied:
- An `AVAudioSession` needs to be active
- An `MPVolumeView` needs to be in the current view's hierarchy, and its alpha needs to be greater than 0
Once a `SubtleVolume` is added to your view, an audio session is automatically started, and the view's alpha is set to `0.0001` in the hidden state.
# Getting Started
Create an instance of `SubtleVolume` with one of its convenience initializers, and set its position (you can either set the frame or let autolayout handle it):
```swift
let volume = SubtleVolume(style: .plain)
volume.frame = CGRect(x: 0, y: 10, width: UIScreen.main.bounds.width, height: 4) // or wherever you like
```
Set the barTintColor property:
```swift
volume.barTintColor = .red
```
Set the animation type if needed (no animation will result in the indicator being always visible):
```swift
volume.animation = .slideDown
```
Add the view to your hierarchy:
```swift
view.addSubview(volume)
```
To change the volume programmatically:
```swift
try? volume.setVolumeLevel(0.5)
```
Or use the convenience methods:
```swift
try? volume.decreaseVolume(by: 0.2, animated: true)
try? volume.increaseVolume(by: 0.2, animated: true)
```
### Accessory image
You can provide an accessory image that will be shown to the bar's left. See the delegate method:
```swift
func subtleVolume(_ subtleVolume: SubtleVolume, accessoryFor value: Double) -> UIImage? {
return value > 0 ? #imageLiteral(resourceName: "volume-on.pdf") : #imageLiteral(resourceName: "volume-off.pdf")
}
```
### iPhone X(S/R) support
Want to be fancy and show the volume bar in the notch area? Check out the demo project. The main gist is this:
```swift
class ViewController: UIViewController {
let volume = SubtleVolume(style: .rounded)
var statusBarVisible = true
// ...
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if view.safeAreaInsets.top > 0 {
volume.padding = CGSize(width: 2, height: 8)
volume.frame = CGRect(x: 16, y: 8, width: 60, height: 20)
} else {
// older phones here
}
}
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation {
return .slide
}
override var prefersStatusBarHidden: Bool {
return !statusBarVisible
}
}
extension ViewController: SubtleVolumeDelegate {
func subtleVolume(_ subtleVolume: SubtleVolume, didChange value: Double) {
if !subtleVolume.isAnimating && view.safeAreaInsets.top > 0 {
statusBarVisible = true
UIView.animate(withDuration: 0.1) {
self.setNeedsStatusBarAppearanceUpdate()
}
}
}
func subtleVolume(_ subtleVolume: SubtleVolume, willChange value: Double) {
if !subtleVolume.isAnimating && view.safeAreaInsets.top > 0 {
statusBarVisible = false
UIView.animate(withDuration: 0.1) {
self.setNeedsStatusBarAppearanceUpdate()
}
}
}
}
```
# Handle the background state
Once your app goes in background, you'll need to resume the session when it becomes active:
```swift
NotificationCenter.default.addObserver(volume, selector: #selector(SubtleVolume.resume), name: NSNotification.Name.UIApplicationDidBecomeActive, object: nil)
```
SubtleVolume automatically removes the observer on deinit.
