iOS-音頻和視頻，iOS-音頻視頻
一、視頻

MPMoviePlayerController播放本地視頻資源

NSString *path = [[NSBundle mainBundle]pathForResource:@"root" ofType:@"mp4"];NSURL *url = [NSURL fileURLWithPath:path];_playcontroller = [[MPMoviePlayerController alloc]initWithContentURL:url];_playcontroller.view.frame = CGRectMake(0, 100, 320, 300);[_playcontroller play];[self.view addSubview:_playcontroller.view];

 MPMoviePlayerController播放網路資源（伺服器為自己搭建，地址不可使用）

NSURL *url = [NSURL URLWithString:@"http://localhost:8080/media/root.mp4"];_playcontroller.view.frame = CGRectMake(0, 100, 320, 300);
[_playcontroller play];[self.view addSubview:_playcontroller.view];

 可以加一個通知，在視頻播放完畢的時候發出通知，將視圖從介面上移除。

- (void)viewDidLoad{    [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(removeMedia) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];}-(void)removeMedia{    [_playcontroller.view removeFromSuperview];}

 MPMoviePlayerViewController播放視頻資源

NSURL *url = [NSURL URLWithString:@"http://localhost:8080/media/root.mp4"];MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc]initWithContentURL:url];[self presentViewController:player animated:YES completion:nil];

 ：

-(BOOL)shouldAutorotate{ return YES;}-(NSUInteger)supportedInterfaceOrientations{ return UIInterfaceOrientationMaskLandscape;}

 然後在實現下面代碼：

NSURL *url = [NSURL URLWithString:@"http://localhost:8080/media/root.mp4"];myMPMoviePlayerViewController *player = [[myMPMoviePlayerViewController alloc]initWithContentURL:url];[self presentViewController:player animated:YES completion:nil];

 為：

@interface ViewController : UIViewController{ //音頻播放器 AVAudioPlayer * _audioPalyer; IBOutlet UISlider *_slider; float currentProgress; NSTimer *_timer;}- (IBAction)playButton:(id)sender;- (IBAction)stopButton:(id)sender;@end

- (void)viewDidLoad{    [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.    _slider.value = 0.0;}- (IBAction)playButton:(id)sender{   _timer = [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(moveSlide) userInfo:nil repeats:YES];        NSString *path = [[NSBundle mainBundle]pathForResource:@"1" ofType:@"mp3"];    NSData *data = [NSData dataWithContentsOfFile:path];    _audioPalyer = [[AVAudioPlayer alloc]initWithData:data error:nil];    [_audioPalyer play];        _slider.maximumValue = _audioPalyer.duration;    [_slider addTarget:self action:@selector(changeSlide) forControlEvents:UIControlEventValueChanged];}-(void)changeSlide{    _audioPalyer.currentTime = _slider.value;}-(void)moveSlide{    _slider.value = _audioPalyer.currentTime;}- (IBAction)stopButton:(id)sender{    UIButton *button = (UIButton *)sender;       if (button.tag == 0)    {        [_audioPalyer pause];        [button setTitle:@"繼續播放" forState:UIControlStateNormal];        button.tag = 1;        [_timer invalidate];        _timer = nil;    }    else    {        [_audioPalyer play];        [button setTitle:@"暫停" forState:UIControlStateNormal];        button.tag = 0;        [_slider addTarget:self action:@selector(changeSlide) forControlEvents:UIControlEventValueChanged];    }}
