MPMoviePlayerController
用来播放视频,在iOS9之后被弃用(iOS9之后苹果推荐我们使用AVPlayer,AVPlayer相对复杂但灵活),由于APP往往要兼容iOS9之前的版本,所有MPMoviePlayerController还是很重要的。
在我的另一篇文章中分享了一个
基于MPMoviePlayerController
的播放器
,大家可以看看,目前还不完整。小伙伴们可以关注一下我的简书。谢谢
MPMoviePlayerController的简单使用 需要添加这个框架MediaPlayer.framework #import
#pragma mark - 本地 NSString* _moviePath=[[NSBundle mainBundle]pathForResource:@"popeye" ofType:@"mp4"]; self.player=[[MPMoviePlayerController alloc]initWithContentURL:[NSURL fileURLWithPath:_moviePath]]; [self.view addSubview:self.player.view]; self.player.view.frame=CGRectMake(0, 0, self.view.frame.size.width, CGRectGetWidth(self.view.frame)*(9.0/16.0)); self.player.movieSourceType = MPMovieSourceTypeFile;// 播放本地视频时需要这句 // self.player.controlStyle = MPMovieControlStyleNone;// 不需要进度条 self.player.shouldAutoplay = YES;// 是否自动播放(默认为YES) // self.player.scalingMode=MPMovieScalingModeAspectFill; [self.player prepareToPlay];//缓存 // [self.player play];//可以不加这句
#pragma mark - 网络 NSURL* url = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"]; _player = [[MPMoviePlayerController alloc] initWithContentURL:url]; [self.view addSubview:self.player.view]; self.player.view.frame=CGRectMake(0, 0, self.view.frame.size.width, CGRectGetWidth(self.view.frame)*(9.0/16.0)); [self.player prepareToPlay]; [self.player play];
#pragma mark - 直播
NSURL* url = [NSURL URLWithString:@"http://live.hkstv.hk.lxDNS.com/live/hks/playlist.m3u8"];
_player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[self.view addSubview:self.player.view];
self.player.view.frame=CGRectMake(0, 0, self.view.frame.size.width, CGRectGetWidth(self.view.frame)*(9.0/16.0));
self.player.controlStyle=MPMovieSourceTypeStreaming;//直播
[self.player prepareToPlay];
// [self.player play];
MPMoviePlayerController提供了很多通知,这里我就简单的监听2个。我们可以通过监听到的信息做相应的处理。
#pragma mark - Notification
//监听视频播放结束
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(endPlay) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
//监听当前视频播放状态
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(loadStateDidChange:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
#pragma mark - Notification function
-(void)endPlay
{
NSLog(@"播放结束");
}
-(void)loadStateDidChange:(NSNotification*)sender
{
switch (self.player.loadState) {
case MPMovieLoadStatePlayable:
{
NSLog(@"加载完成,可以播放");
}
break;
case MPMovieLoadStatePlaythroughOK:
{
NSLog(@"缓冲完成,可以连续播放");
}
break;
case MPMovieLoadStateStalled:
{
NSLog(@"缓冲中");
}
break;
case MPMovieLoadStateUnknown:
{
NSLog(@"未知状态");
}
break;
default:
break;
}
}
#pragma mark - dealloc
- (void)dealloc
{
[[NSNotificationCenter defaultCenter]removeObserver:self];
}
