如何在UITableView中獲取視頻的文件路徑？ （tmp目錄）

Question

我在顯示一個UITableView的tmp目錄的內容，但不能得到每個單元的文件路徑。

當按下電池，我的應用程序應該發揮與MPMoviePlayer的文件，但並非如此。

這是我到目前爲止有：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 


NSString *tmpDirectory = NSTemporaryDirectory(); 
fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:tmpDirectory error:nil]; //nsarray 

NSString *movieURL = [fileList objectAtIndex:indexPath.row]; 

NSURL *url = [NSURL URLWithString:movieURL]; 

_moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; 

[self presentModalViewController:_moviePlayerViewController animated:YES]; 
} 

的NSLog給我視頻的名稱，而不是路徑。我覺得我正在從睡眠不足的角度思考這個問題。

Answer 1

當您使用此：

NSString *movieURL = [fileList objectAtIndex:indexPath.row]; 

它會在臨時目錄中只返回文件名， 所以用這個：

NSString *movieURL = [tmpDirectory stringByAppendingPathComponent:[fileList objectAtIndex:indexPath.row]]; 

NSURL*url = [NSURL fileURLWithPath:movieURL]; 

Answer 2

更改您的代碼，如：

NSString *tmpDirectory = NSTemporaryDirectory(); 
    NSLog(@"%@",tmpDirectory); 
    NSArray *fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:tmpDirectory error:nil]; //nsarray 

    NSString *movieURL = [fileList objectAtIndex:indexPath.row]; 
    NSString *path=[tmpDirectory stringByAppendingPathComponent:movieURL]; 

Answer 3

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 
    let tmpDirectory: String = NSTemporaryDirectory() 
    print("\(tmpDirectory)") 
    var fileList: [Any]? = try? FileManager.default.contentsOfDirectory(atPath: tmpDirectory) 
    //nsarray 
    let movieURL: String? = (fileList?[indexPath.row] as? String) 
    let path: String = URL(fileURLWithPath: tmpDirectory).appendingPathComponent(movieURL!).absoluteString 
    print(path) 
}
