VolumeBar is a Swift volume indicator that doesn't obstruct content on screen. A basic implementation is just one line of code, but it can be heavily customized via several appearance and presentation properties.

• Customizable appearance
• Orientation change support
• Hides system volume HUD automatically
• Simple API

Current Swift compatibility breakdown:

A basic implementation of VolumeBar is just one line of code.

VolumeBar.sharedInstance.start()

By default, adding VolumeBar to your app will cause background audio to pause when your app is opened. To prevent this, add the following line of code wherever you call the start method:

try! AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)

Calling the start method begins observing changes in the system volume. After calling start, VolumeBar will show automatically whenever your app is active and the volume changes. This is appropriate for most use cases. To stop observing changes and use the system volume HUD again, call stop:

VolumeBar.sharedInstance.stop()

Please see the documentation and check out the sample app (VolumeBarSample) for more details.

Customize tint color, bar tint color, and track tint color:

VolumeBar.sharedInstance.tintColor = UIColor.white
VolumeBar.sharedInstance.backgroundColor = UIColor.black.withAlphaComponent(0.5)
VolumeBar.sharedInstance.trackTintColor = UIColor.clear

Customize layout properties:

VolumeBar.sharedInstance.barHeight = 5
VolumeBar.sharedInstance.segmentCount = 8
VolumeBar.sharedInstance.interitemSpacing = 5

If start has been called, VolumeBar will automatically show when the system volume changes. You can also manually show and hide VolumeBar.

VolumeBar.sharedInstance.show()
VolumeBar.sharedInstance.hide()

Change the animation style:

VolumeBar.sharedInstance.animationStyle = .fade // default is .slide
VolumeBar.sharedInstance.animationDuration = 0.5
VolumeBar.sharedInstance.minimumVisibleDuration = 2.0

VolumeBar needs to know when the status bar is hidden or changes style. These properties should be updated in the viewWillAppear method of each view controller.

VolumeBar.sharedInstance.statusBarHidden = false
VolumeBar.sharedInstance.statusBarStyle = .lightContent
