IOS 播放视频 MPMoviePlayerController

在unity游戏的开头播放视频 ， 根据需求 ， 最后决定用 MPMoviePlayerController 来实现播放， 实现如下： by Tin

需要在AppController.mm的 OpenEAGL_UnityCallback 修改下view的大小

UIView *mainView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
// mainView.backgroundColor = [UIColor grayColor];

[MyViewController Instance].view = mainView;

[UnityGetGLViewController().view addSubview: [MyViewController Instance].view];

需要在游戏中接收unity的命令

// ========================   播放开头动画  start ========================

void PlayMovieInIOS( char * path )
{
[[MyViewController Instance] PlayVideo:[NSString stringWithUTF8String:path]];

}

void exPlayVideo( char * url )
{
[[MyViewController Instance] PlayVideo:[NSString stringWithUTF8String:url]];
}

void exReleaseVideo()
{
[[MyViewController Instance] ReleaseVideo];
}

MovieViewController *  mv ;

-(void) PlayVideo:(NSString *)  path
{
if ( mv != nil) {
[mv breakMovie] ;
[mv release];
mv= nil ;
}

mv = [[ MovieViewController alloc] init];
[self.view addSubview:mv.view];
[mv playMovie:path];
}

-(void) ReleaseVideo
{
if ( mv != nil) {
[mv breakMovie] ;
[mv release];
mv= nil ;
}

UnitySendMessage("_IOSDoor","ReleaseVideoOver", "");
}

// ========================   播放开头动画  end ========================

接下来是播放视频

MPMoviePlayerController *movie ;

/**
@method 播放电影
*/
-(void)playMovie:(NSString *)fileName{

NSURL *url = [NSURL fileURLWithPath: fileName ];
//视频播放对象
movie = [[MPMoviePlayerController alloc] initWithContentURL:url];
movie.controlStyle = MPMovieControlStyleNone;
[movie.view setFrame:self.view.bounds];
movie.initialPlaybackTime = -1;
[self.view addSubview:movie.view];
// 注册一个播放结束的通知
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:movie];

[movie play];
}

#pragma mark -------------------视频播放结束委托--------------------

-(void)  breakMovie
{
if (movie == nil) {
return ;
}

//销毁播放通知
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:movie];
[movie.view removeFromSuperview];
// 释放视频对象
[movie release];
movie = nil ;
}

/*
@method 当视频播放完毕释放对象
*/
-(void)myMovieFinishedCallback:(NSNotification*)notify
{

NSNumber *reason =
[notify.userInfo
valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
if (reason != nil){
NSInteger reasonAsInteger = [reason integerValue];
switch (reasonAsInteger){
case MPMovieFinishReasonPlaybackEnded:{
/* The movie ended normally */
break; }
case MPMovieFinishReasonPlaybackError:{
/* An error happened and the movie ended */
break;
}
case MPMovieFinishReasonUserExited:{
/* The user exited the player */
break;
}
}
NSLog(@"Finish Reason = %ld", (long)reasonAsInteger);
}

/* 取消视频自动销毁  由break mv 执行
//视频播放对象
MPMoviePlayerController* theMovie = [notify object];
//销毁播放通知
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
[theMovie.view removeFromSuperview];
// 释放视频对象
[theMovie release];
movie = nil ;
NSLog(@"---------PlayVideoOver 11");
*/

UnitySendMessage("_IOSDoor","PlayVideoOver", "");
NSLog(@"---------PlayVideoOver 22");
}
