我正在尝试在我的 ViewController 中播放视频。Mediaplayer.framework 和所有标题都在我的 Frameworks 文件夹中,包括 MediaPlayer.h 文件。但是当我把
#import "TutorialViewController.h"
#import <MediaPlayer/MediaPlayer.h>
@interface TutorialViewController ()
@end
@implementation TutorialViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
//---play movie---
[player play];
[super viewDidLoad];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
// Do any additional setup after loading the view.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
@end
在我的 .m 文件中,我收到一条错误消息,指出找不到“MediaPlayer/MediaPlayer.h”文件。这是什么意思,我该如何解决?
