IOS音频和视频(Audio & Video)
简介
音频和视频在**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)。
我赢职场IOS音频和视频教程的学习：
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
