2 개의 절반으로 구성된 UIViewController가 있습니다 (실제로는 UIContainerViews에 있음). 1 1/2에는 PDF를 표시하는 데 사용되는 UIWebView가 있고 다른 절반에는 비디오를 스트리밍하는 데 사용되는 UIView가 포함되어 있습니다. 모달 전체 화면 iOS 8 이후 비디오가 mpmovieplayercontroller에서 재생되지 않습니다.
- (IBAction)pressedFullscreenButton:(id)sender
{
// pause the video view controller
self.videoViewController.videoPlayer pause];
// perform the segue - this is modal, full screen
[self performSegueWithIdentifier:@"FullscreenSegue" sender:self];
}
누르면 전체 화면 모드에서 모달있는 UIWebView를 제시하는있는 UIButton과 함께있는 UIWebView와 탐색 모음은있다 모달, 전체 화면으로 표시됩니다. 이 전체 화면보기 컨트롤러를 닫아서 분할 화면으로 돌아갈 때, 비디오에서 재생을 누르면 오디오가 재생되지만 비디오는 재생되지 않으며 그 이유를 알 수 없습니다. 고맙습니다.
이것을 얻으려면 내 선호하는 솔루션이 아닙니다. 기본적으로 비디오의 현재 시간을 가져 와서 중지하고, 현재 시간을 설정하고, 비디오를 재생하고,보기 컨트롤러가 나타날 때 일시 중지합니다.
그래서 내가 StandardVideoPlayer라는 클래스에 랩 가지고 MPMoviePlayerController 사용 : 여기 내 코드입니다
@implementation StandardVideoPlayer
-(id)initWithParentView:(UIView *)parent andAutoPlay:(BOOL)autoPlay andFullScreen:(BOOL)fullScreen andAnimated:(BOOL)animated
{
// Call superclass's initializer
self = [super init];
if(!self || !parent)
{
return nil;
}
else
{
if (!_moviePlayerController)
{
_moviePlayerController = [[MPMoviePlayerController alloc] init];
}
_moviePlayerController.controlStyle = MPMovieControlStyleDefault;
[_moviePlayerController.view setFrame:parent.frame];
[_moviePlayerController.view setCenter:parent.center];
_moviePlayerController.allowsAirPlay = YES;
_moviePlayerController.shouldAutoplay = autoPlay;
[_moviePlayerController setFullscreen:fullScreen animated:animated];
[parent addSubview: [self videoView]];
}
return self;
}
-(void)loadFromFile: (NSString*) filePath;
{
if (_moviePlayerController)
{
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
[_moviePlayerController setContentURL:fileUrl];
[_moviePlayerController prepareToPlay];
}
}
- (void)loadFromURL: (NSString*) urlString
{
if ([[ConnectionManager sharedInstance] canConnect])
{
if (_moviePlayerController)
{
NSURL *url = [NSURL URLWithString:urlString];
[_moviePlayerController setContentURL:url];
[_moviePlayerController prepareToPlay];
}
}
else
{
[[ConnectionManager sharedInstance] displayConnectionWarningWithText:@"Ok" andDelegate:nil];
}
}
-(void)loadFromHTML:(NSString *)html
{
// NSString *h = [NSString stringWithFormat:html, ]
}
-(void)play
{
if (_moviePlayerController)
{
[_moviePlayerController prepareToPlay];
[_moviePlayerController play];
}
}
-(void)stop
{
if (_moviePlayerController)
{
[_moviePlayerController stop];
}
}
-(void)pause
{
if (_moviePlayerController)
{
[_moviePlayerController pause];
}
}
// use this to get the view form the moviePlayerController......
-(UIView*)videoView
{
UIView *view = nil;
if (_moviePlayerController)
{
view = _moviePlayerController.view;
}
return view;
}
@end
와 다음 뷰 컨트롤러에 내가있다 :
@implementation VideoViewController
// lazy initialiser
- (StandardVideoPlayer*) videoPlayer

{
_videoPlayer = [[StandardVideoPlayer alloc] initWithParentView:self.view andAutoPlay:NO andFullScreen:NO andAnimated:YES];
