Png. we are going to additionally desire a few MP3 sounds for this recipe. obtain 3 sounds for the piano notes and one other 3 for the drums; after all, we can't have any sound for the remainder be aware. position the images that have been downloaded into your pictures. xcassets folder. for those who like, it's also possible to upload an analogous images with assorted resolutions to be used in numerous answer units (iPad and iPhone). sooner than you begin, we'll simply have to upload a framework referred to as AVFoundation. this can let our app to play sounds. to do that, simply click the undertaking navigator, then click construct levels. After this, extend the hyperlink binary with Libraries part, then click the plus button. pick out AVFoundation and press upload. how you can do it... As ordinary, we are going to commence with the versions. First, let's create a notice protocol, as we all know that during destiny we will have multiple form of word and we must always be ready for it. So, create a brand new dossier known as NoteProtocol. rapid and placed the next code:import origin import UIKit enum NoteStep { case NOTE_C, NOTE_D, NOTE_E } protocol NoteProtocol { var sound:String? { get set } var image:UIImage? { get set } var step: NoteStep { get set } var location:CGPoint { get set } func play() } the next move is to create an implementation of this protocol. Create a dossier referred to as MusicalNote. fast and upload the next content material in it:import starting place import UIKit import AVFoundation classification MusicalNote: NoteProtocol{ lazy inner most var _player = AVAudioPlayer() inner most var _sound:String? var sound:String? { get { go back _sound } set(newSound){ self. _sound = newSound } } deepest var _image:UIImage? var image:UIImage? { get{ go back _image} set(newImage){ self. _image = newImage } } deepest var _step:NoteStep var step: NoteStep { get{ go back _step } set(newStep){ self. _step = newStep } } inner most var _location:CGPoint var location:CGPoint { get { go back _location } set(newLocation){ self. _location = newLocation } } func play(){ if enable mySound = _sound { var urlSound = NSURL(fileURLWithPath: NSBundle. mainBundle(). pathForResource(mySound, ofType: "mp3")! ) self. _player = AVAudioPlayer(contentsOfURL: urlSound, errors: nil) self. _player. prepareToPlay() self. _player. play() } } init(_ step:NoteStep = . NOTE_C){ self. _location = CGPointZero self. _step = step } } Now that we have got applied our observe type, see to it that this notice isn't really piano-specific or drum-specific; we in simple terms have to construct it another way in accordance with the observe style and step. So, now we have to outline a manufacturing facility of notes. With a similar good judgment we had utilized ahead of, we now have to create a protocol of a observe. the one process that we are going to outline is createNote, and it must recognize the observe step (C, D, or E) and its place at the employees. it is time to create a brand new dossier referred to as AbstractNoteFactory. quick and kind the subsequent code: protocol AbstractNoteFactory { func createNote(noteStep:NoteStep, order:Int) -> NoteProtocol } when we have the definition of a notice manufacturing unit, we will begin developing our personal factories. Let's commence with the best one: SilenceFactory; this manufacturing unit will create just one form of word, regardless of its step.
