iOS - Audio & Video

Advertisements


Introduction

Audio and video is quite common in latest devices. It is supported in iOS with the help of AVFoundation.framework and MediaPlayer.framework respectively.

Steps Involved

1. Create a simple View based application.

2. Select your project file, select targets, and then we should add AVFoundation.framework and MediaPlayer.framework.

3. Add two buttons in ViewController.xib and create an action for playing audio and video respectively.

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

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

Now when we run the application we'll get the following output.
