  • Playing Audio on an iPhone using AVAudioPlayer - Techotopia
    the numberofLoops property Creating the iPhone Audio Example Application The remainder of this chapter will work through the creation of a simple iPhone iOS 5 application which plays an audio file The user interface of the application will consist of play and stop buttons to control playback and a slider to adjust the playback volume level Begin by launching Xcode and creating a new iPhone iOS Single View Application named audio with a matching class prefix Adding the AVFoundation Framework Since the iOS 5 AVAudioPlayer class is part of the AV Foundation framework it will be necessary to add the framework to the project This can be achieved by selecting the product target entry from the project navigator panel the top item named audio and clicking on the Build Phases tab in the main panel In the Link Binary with Libraries section click on the button select the AVFoundation framework entry from the resulting panel and click on the Add button Adding an Audio File to the Project Resources In order to experience audio playback it will be necessary to add an audio file to the project resources For this purpose any supported audio format file will be suitable Having identified a suitable audio file drag and drop it into the Supporting Files category of the project navigator panel of the main Xcode window For the purposes of this tutorial we will be using an MP3 file named Kalimba mp3 Creating Actions and Outlets The application is going to require action methods for the play and stop buttons in addition to the volume control Since we will need to be able to read the current value of the volume slider control it will also be necessary to declare a corresponding outlet We also need to declare a reference to an AVAudioPlayer audioPlayer object and specify that the view controller class implements the AVAudioPlayerDelegate protocol Select the audioViewController h file and modify it to import the AVFoundation AVFoundation h file and declare these references and actions import UIKit UIKit h import AVFoundation AVFoundation h interface audioViewController UIViewController AVAudioPlayerDelegate AVAudioPlayer audioPlayer UISlider volumeControl property strong nonatomic IBOutlet UISlider volumeControl IBAction playAudio IBAction stopAudio IBAction adjustVolume end Implementing the Action Methods The next step in our iPhone audio player tutorial is to implement the action methods for the two buttons and the slider Select the audioViewController m file and add these methods as outlined in the following code fragment note also the addition of the synthesize directive for the volumeControl import audioViewController h implementation audioViewController synthesize volumeControl void playAudio audioPlayer play void stopAudio audioPlayer stop void adjustVolume if audioPlayer nil audioPlayer volume volumeControl value Creating Initializing the AVAudioPlayer Object Now that we have an audio file to play and appropriate action methods written the next step is to create an AVAudioPlayer instance and initialize it with a reference to the audio file Since we only need to initialize the object once when the application launches a good place to write this code is

    to Twitter accounts though this will likely be extended to other platforms such as Facebook in future iOS releases Using the Accounts framework code can be written to access create and validate Twitter accounts on iOS 5 based devices The iOS 5 operating system running on iPhone and iPad devices is able to store multiple Twitter accounts which are accessible both from the device Settings application in addition to using the Accounts Framework within application code To manually view and configure Twitter accounts on a device select the Settings application and choose the Twitter option Any pre configured Twitter accounts will be listed together with a button providing the option to add a new Twitter account and switches providing control over which applications may be granted permission to access those Twitter accounts Figure 54 1 When using the TWRequest class to construct Twitter API requests it will be necessary to use the Accounts framework to identify and request permission to use Twitter accounts in an application When using the TWTweetComposeViewController however the account handling is performed automatically by the class The TWTweetComposeViewController Class As previously discussed the TWTweetComposeViewController class presents the user with a screen that can be used to send a Twitter message Figure 54 2 provides an illustration of the class in action within an iPhone application Figure 54 2 In order to use the TWTweetComposeViewController class a number of steps should be performed in sequence Firstly the application may optionally check to verify whether a Twitter message can be sent using the device This essentially equates to checking if a Twitter account has been configured on the device and is achieved using the canSendTweet class method as follows if TWTweetComposeViewController canSendTweet Device is able to send a Twitter message This method call is optional and in the event that a Twitter account has yet to be set up the composer will simply take to the user to the device s Settings application where a Twitter account may be configured The next step is to create an instance of the TWTweetComposeViewController class and supply an optional completion handler to be called when the composer screen is either cancelled by the user or used to send a message Next a range of methods may be called on the instance to initialize the object with the content of the message including the initial text of the message an image attachment and a URL setInitialText Sets the initial text of the Twitter message on the TWTweetComposeViewController instance addImage Adds image files as attachments to the message The class automatically handles URL shortening and resizing of the image for Twitter image hosting compatibility addURL Adds a URL to the Twitter message The method automatically handles the URL shortening Each of the above methods returns a Boolean result indicating whether the addition of content was successful A return value indicating failure typically means either that the Twitter 140 character limit has been exceeded keep in mind that URLs and images in the message
