Вопрос:
Я загрузил видео с URL-адреса, используя AFNetworking и установив пути к видео. Затем доступ к пути для воспроизведения видео. Но когда я нажимаю кнопку для воспроизведения видео, ничего не происходит.
Скачать видео:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"images"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:amp;error];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setValue:@"application/x-www-form-urlencoded"
forHTTPHeaderField:@"Content-Type"];
[manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"video/mpeg", nil];
[manager GET:@"http://center.net/projects/AR/video.mp4"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
[operation.responseData writeToFile:[dataPath stringByAppendingPathComponent:@"video.mp4"] atomically:YES];
NSLog(@"Successfully downloaded file to %@", [NSURL fileURLWithPath:dataPath]);
NSLog(@"THE RESPONSE: %@", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error1) {
NSLog(@"%@", error1);
}];
Воспроизведение видео:
path=[[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"];
mpviewController = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL fileURLWithPath:path]];
[mpviewController.view setFrame:CGRectMake(0, 0, 768, 1024)];
[self.view addSubview:mpviewController.view];
[self presentMoviePlayerViewControllerAnimated:mpviewController];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification object:mpviewController];
Ответ №1:
Ваш путь к видео выглядит следующим образом
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"images"];
NSString *videoPath=[dataPath stringByAppendingPathComponent:@"video.mp4"]; //CORRECT
где, как вы пытаетесь загрузить неправильный файл, как показано ниже
path=[[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"]; //WRONG
