Question

我下载了一个文件：

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:episode.enclosure_url]];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *fileExtension = [episode.enclosure_url pathExtension];
NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:[episode.enclosure_urlAlphanumericOnly stringByAppendingString:[NSString stringWithFormat:@".%@", fileExtension]]];

AFDownloadRequestOperation *operation = [[AFDownloadRequestOperation alloc] initWithRequest:request targetPath:path shouldResume:YES];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

                    // COMPLETION BLOCK
                    NSLog(@"Successfully downloaded file to %@", path);

                    downloadInfo.filePath = path;
                    downloadInfo.isComplete = @YES;

                    // save context
                    NSError *error;
                    BOOL success = [self.workerContext save:&error];
                    if (!success || error) {
                        NSLog(@"%@", error.localizedDescription);
                    }
…

成功完成块触发，记录：

Successfully downloaded file to /Users/myName/Library/Application Support/iPhone Simulator/7.1-64/Applications/D629F52C-E299-42C7-BF7E-DF8D096529C7/Documents/httppodcastdownloadnprorganonnprpodcastspodcast13308789280npr308789280mp3.mp3

然后我检查文件的存在：

if ([[NSFileManager defaultManager] fileExistsAtPath:[localUrl path]]) {
    …

找不到该文件。我也没有在Finder中看到任何新文件。

为什么AFDownloadRequestOperation表示下载成功，但文件似乎不存在？或者，具有恢复功能的下载方式是什么？感谢

找不到用AFDownloadRequestOperation成功下载的文件
