iOS音频和视频(Audio & Video)

IOS音频和视频(Audio & Video)

简介

音频和视频在最新的设备中颇为常见。

将iosAVFoundation.framework和MediaPlayer.framework添加到Xcode项目中，可以让IOS支持音频和视频(Audio & Video)。

实例步骤

1、创建一个简单的View based application

2、选择项目文件、选择目标，然后添加AVFoundation.framework和MediaPlayer.framework

3、在ViewController.xib中添加两个按钮，创建一个用于分别播放音频和视频的动作（action）

4、更新ViewController.h,如下所示

#import

#import

#import

@interface ViewController : UIViewController

{

AVAudioPlayer *audioPlayer;

MPMoviePlayerViewController *moviePlayer;

}

-(IBAction)playAudio:(id)sender;

-(IBAction)playVideo:(id)sender;

@end

5、更新ViewController.m，如下所示

#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

注意项

需要添加音频和视频文件，以确保获得预期的输出
