Simple usage of Audio and Video:

When using audio, You need to import # import <AVFoundation/AVFoundation. h>

@ Interface ViewController ()

{

 

AVPlayer * player;

}

@ End

@ Implementation ViewController

-(Void) viewDidLoad {

[Super viewDidLoad];

Note: AVPlayer must define a global variable. If it is not defined as a global variable, the variable is released with parentheses.

NSURL * url = [NSURL URLWithString: @ "http://bcs.duapp.com/chenwei520/media/music.mp3"];

Player = [[AVPlayer alloc] initWithURL: url];

[Player play]; start playing

[Player stop]; stop playing

[Player pause]; pause playing

}

When using videos, you need to import # import <MediaPlayer/MediaPlayer. h>

Note: MPMoviePlayerController also needs to define global variables. If it is not defined as a global variable, it will be released out of brackets.

@ Interface ViewController ()

{

MPMoviePlayerController * moviePlayer;

}

@ End

@ Implementation ViewController

-(Void) viewDidLoad {

[Super viewDidLoad];

NSString * mp4 = @ "http://bcs.duapp.com/chenwei520/media/mobile_vedio.mp4 ";

NSURL * url = [NSURL URLWithString: mp4];

MoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: url];

MoviePlayer. view. frame = self. view. bounds;

MoviePlayer. view. backgroundColor = [UIColor grayColor];

[MoviePlayer play];

[Self. view addSubview: moviePlayer. view];

}
