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 <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、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

输出

运行该程序,得到的输出结果如下

当我们点击 play video(播放视频)显示如下:
