Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ gem install cocoapods

To integrate Jukebox into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'Jukebox'

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate Jukebox into your Xcode project using Carthage, specify it in your Cartfile:

github "teodorpatras/Jukebox"

Run carthage update to build the framework and drag the built Jukebox.framework into your Xcode project.

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate Jukebox into your project manually.

Supported OS & SDK versions

• iOS 8.0+
• Xcode 7+

Usage

Prerequisites

• In order to support background mode, append the following to your Info.plist:

<key>UIBackgroundModes</key>
<array>
    <string>audio</string>
</array>

• If you want to stream from http:// URLs, append the following to your Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
        <true/>
</dict>

Getting started

1) Create an instance of Jukebox:

// configure jukebox
jukebox = Jukebox(delegate: self, items: [
    JukeboxItem(URL: NSURL(string: "http://www.noiseaddicts.com/samples_1w72b820/2514.mp3")!),
    JukeboxItem(URL: NSURL(string: "http://www.noiseaddicts.com/samples_1w72b820/2958.mp3")!)
    ])

2) Play and enjoy:

jukebox?.play()

Handling remote events

In order to handle remote events, you should do the following:

• First, you need to call for receiving remote events:

UIApplication.sharedApplication().beginReceivingRemoteControlEvents()

• Secondly, override remoteControlReceivedWithEvent(event:):

override func remoteControlReceived(with event: UIEvent?) {
    if event?.type == .remoteControl {
        switch event!.subtype {
        case .remoteControlPlay :
            jukebox.play()
        case .remoteControlPause :
            jukebox.pause()
        case .remoteControlNextTrack :
            jukebox.playNext()
        case .remoteControlPreviousTrack:
            jukebox.playPrevious()
        case .remoteControlTogglePlayPause:
            if jukebox.state == .playing {
               jukebox.pause()
            } else {
                jukebox.play()
            }
        default:
            break
        }
    }
}

Public properties

Delegation

Jukebox defines a delegate protocol which you can use if you want to be announced when about custom events:

public protocol JukeboxDelegate: class {
    func jukeboxStateDidChange(_ state : Jukebox)
    func jukeboxPlaybackProgressDidChange(_ jukebox : Jukebox)
    func jukeboxDidLoadItem(_ jukebox : Jukebox, item : JukeboxItem)
    func jukeboxDidUpdateMetadata(_ jukebox : Jukebox, forItem: JukeboxItem)
}
