Working on iOS Audio and Video Creation
The AV Foundation framework on the iOS SDK permits developers to play and record audio and video with simplicity. In addition the Media Player framework permits developers to play audio and video files.
Before executing the code you have to insert the AVFoundation.framework and MediaPlayer.framework frameworks to Xcode project. This can be achieved using following steps:
Step 1 – Find your target in Xcode project.
Step 2 – Right click on the target and select Add→Existing Frameworks.
Step 3 – Restrain the Command key and select AVFoundation.framework and MediaPlayer.framework from the list.
Step 4 – Choose Add.
Step 5 – Insert 2 buttons in ViewController.xib and make an action for playing audio and video in that order.
Step 6 – Change 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 7 – Change ViewController.m as follows:
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
-(void)viewDidLoad
{
[super viewDidLoad];
}
-(void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
-(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
