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 <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

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：
