下載的視頻 - AFHTTPRequestOperation與NSURLSessionDownloadTask

我嘗試更新我的現有下載的模式，所以我已經取代我的舊代碼：下載的視頻 - AFHTTPRequestOperation與NSURLSessionDownloadTask

AFHTTPRequestOperation *downloadRequest = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 
[downloadRequest setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 
    NSData *data = [[NSData alloc] initWithData:responseObject]; 
    [data writeToFile:video2Save.localFilePath atomically:YES]; 

    video2Save.downloadComplete = YES; 
    [YEPersistentModelHelper saveData:_downloadVideos ToDiskWithIdentifier:persistentIdDownloadedVideos]; 

    NSLog(@"file downloading complete : %@", video2Save.localFilePath); 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"file downloading error : %@", [error localizedDescription]); 
}]; 
[downloadRequest start];*/

下列要求：

NSURLSessionDownloadTask *downloadTask = [_sessionManager downloadTaskWithRequest:request progress:&progress destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { 
    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil]; 
    return [documentsDirectoryURL URLByAppendingPathComponent:[NSString stringWithFormat:@"%@.mp4",video2Save.videoVersionId]]; 

} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { 
    NSLog(@"File downloaded to: %@", filePath); 
    video2Save.localFilePath = [[filePath filePathURL] absoluteString]; 
    video2Save.downloadComplete = YES; 
    [YEPersistentModelHelper saveData:_downloadVideos ToDiskWithIdentifier:persistentIdDownloadedVideos]; 


    NSFileManager *fileManager = [NSFileManager defaultManager]; 
    NSError *err = nil; 
    NSDictionary *att = [fileManager attributesOfItemAtPath:video2Save.localFilePath error:&err]; 
    NSLog(@"NSDictionary: %@", att); 

}]; 
[downloadTask resume];

而且它似乎工作正常。完成塊被執行&該文件存在於跟蹤目標。

問題是，我不再可以播放視頻！我用它拋出這個有用的錯誤的MPMoviePlayerController：

_itemFailedToPlayToEnd: { kind = 1; new = 2; old = 0; }

唯一的區別似乎是該文件的權限。第一個增加了一個「員工」組&每個人都可以閱讀，而第二個只允許訪問「我」。但即使我在取景器中更改它，我也無法播放它...

有沒有人有想法？

保存位置的文件路徑使用沒有absoluteString

video2Save.localFilePath = [[文件路徑filePathURL] absoluteString];

不叫absoluteString甚至玩..只是使用路徑這樣例如調用視頻

NSURL *FilePathURL = [NSURL fileURLWithPath:[docDir stringByAppendingPathComponent:fileToCheck]]; 
    [[myvideoCalss :[FilePathURL path]]

哎，我認爲這可能觸發此有用的錯誤;） – niggeulimann
