iOS音(yīn)頻和(hé)視(shì)頻(Audio & Video)

IOS音(yīn)頻和(hé)視(shì)頻(Audio & Video)

簡介

音(yīn)頻和(hé)視(shì)頻在最新的設備中頗爲常見。

将iosAVFoundation.framework和(hé)MediaPlayer.framework添加到(dào)Xcode項目中，可以讓IOS支持音(yīn)頻和(hé)視(shì)頻(Audio & Video)。

實例步驟

1、創建一個簡單的View based application

2、選擇項目文(wén)件、選擇目标，然後添加AVFoundation.framework和(hé)MediaPlayer.framework

3、在ViewController.xib中添加兩個按鈕，創建一個用(yòng)于分别播放(fàng)音(yīn)頻和(hé)視(shì)頻的動作(zuò)（action）

4、更新ViewController.h,如下(xià)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(xià)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

注意項

需要添加音(yīn)頻和(hé)視(shì)頻文(wén)件，以确保獲得預期的輸出
