iOS - Audio and Video
Audio and video is quite common in the latest devices. It is supported in iOS with the help of AVFoundation.framework and MediaPlayer.framework respectively.
Steps Involved
Step 1 − Create a simple View based apppcation.
Step 2 − Select your project file, select targets, and then we should add AVFoundation.framework and MediaPlayer.framework.
Step 3 − Add two buttons in ViewController.xib and create an action for playing audio and video respectively.
Step 4 − Update ViewController.h as follows −
#import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> #import <MediaPlayer/MediaPlayer.h> @interface ViewController : UIViewController { AVAudioPlayer *audioPlayer; MPMoviePlayerViewController *moviePlayer; } -(IBAction)playAudio:(id)sender; -(IBAction)playVideo:(id)sender; @end
Step 5 − Update ViewController.m as follows −
#import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } -(IBAction)playAudio:(id)sender { NSString *path = [[NSBundle mainBundle] pathForResource:@"audioTest" ofType:@"mp3"]; audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL: [NSURL fileURLWithPath:path] error:NULL]; [audioPlayer play]; } -(IBAction)playVideo:(id)sender { NSString *path = [[NSBundle mainBundle]pathForResource: @"videoTest" ofType:@"mov"]; moviePlayer = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL fileURLWithPath:path]]; [self presentModalViewController:moviePlayer animated:NO]; } @end
Note
We need to add audio and video files for ensuring that we get the expected output.
Output
When we run the apppcation, we ll get the following output −
When we cpck on play video, we will get an output as shown below −
When we cpck play audio, you will hear the audio.
