This can be extremely annoying and a big vibe-killer that interrupts the natural flow of otherwise awesome music. Imagine playing your favorite song and having the record skip forward or backward seemingly randomly. ![]() One of these issues is the music on your record player skipping. Repeat these steps to establish outlet connections for the “Play” and “Stop” buttons named playButton and stopButton respectively.Ĭontinuing to use the Assistant Editor, establish Action connections from the three buttons to methods named recordAudio, playAudio and stopAudio.Ĭlose the Assistant Editor panel, select the ViewController.As with every good thing, specific issues can come up when playing vinyl records. Release the line and establish an outlet connection named recordButton. Ctrl-click on the Record button object and drag to a position just below the class declaration line in the Assistant Editor. Select the “Record” button object in the view canvas, display the Assistant Editor panel and verify that the editor is displaying the contents of the ViewController.swift file. With the scene view selected within the storyboard canvas, display the Auto Layout Resolve Auto Layout Issues menu and select the Reset to Suggested Constraints menu option listed in the All Views in View Controller section of the menu. Once placed in the view, modify the text on each button so that the user interface appears as illustrated in Figure 96-3: Select the Main.storyboard file and, once loaded, drag Button objects from the Object Library window (View -> Utilities -> Show Object Library) and position them on the View window. Once the usage key has been configured, the entry within the property list editor should match that shown in Figure 96-2: Once the key has been specified, set the corresponding value field to read as follows: The audio recorded by this app is stored securely and is not shared. Click on the key field for the new entry and locate and select the Privacy – Microphone Usage Description menu option as illustrated in Figure 96-1: Select the last entry in the list and click on the + button to add a new entry. To add this value, select the ist file in the project navigator panel to load it into the property list editor. The absence of this key will result in the app crashing at runtime. This text message must be specified within the ist file using the NSMicrophoneUsageDescription key. Included within the content of this dialog is a message from the app providing justification for using the microphone. When an app attempts to access the microphone, the operating system will display a warning dialog to the user seeking authorization for the app to proceed. The view controller of the example application will also implement the AVAudioRecorderDelegate and AVAudioPlayerDelegate protocols and a number of corresponding delegate methods in order to receive notification of events relating to playback and recording.Īccess to the microphone from within an iOS 10 app is considered to be a potential risk to the privacy of the user. Playback of the recorded audio file will be performed using the AVAudioPlayer class which was covered in detail in the chapter entitled Playing Audio on iOS 10 using AVAudioPlayer.Īudio recording and playback will be controlled by buttons in the user interface that are connected to action methods which, in turn, will make appropriate calls to the instance methods of the AVAudioRecorder and AVAudioPlayer objects respectively. It will do so by creating an instance of the AVAudioRecorder class and configuring it with a file to contain the audio and a range of settings dictating the quality and format of the audio. The goal of this chapter is to create an iOS 10 application that will record and playback audio. An Overview of the AVAudioRecorder Tutorial ![]()
