解析爲目標C URL地址

我試圖獲取元數據的URL地址元頭，我使用此代碼解析爲目標C URL地址

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://www.youtube.com/watch?v=1cuMAeGOCng"]]; 
    [request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Safari/601.1.42" 
    forHTTPHeaderField:@"User-Agent"]; 

    self.session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 
    NSURLSessionTask *task = [self.session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) { 
     NSLog(@"%@",data); 
    }]; 
    [task resume];

是這樣吧？也返回的數據進行編碼，並不能如何解碼！任何線索？

它是正確轉換的NSData到的NSString 的NSLog（@ 「％@」，[[ALLOC的NSString] initWithData：數據編碼：NSUTF8StringEncoding]）; –

@MohammadAlavi是的，數據現在是可讀的，但獲取的信息是關於整個網站！ – OXXY

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: 
[NSURL URLWithString:@"https://www.youtube.com/watch?v=1cuMAeGOCng"]]; 
[request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Safari/601.1.42" 
forHTTPHeaderField:@"User-Agent"]; 

session = [NSURLSession sessionWithConfiguration: 
[NSURLSessionConfiguration defaultSessionConfiguration]]; 

NSURLSessionTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) 
          { 

    NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; 
     NSLog(@"Data = %@",text); 


          }]; 
    [task resume];
